Accurate counting of biological entities underpins many fields such as health, safety, environment, biotechnology and food. For example, accurate measurement of the number of biological entities is of great importance in areas such as viral load monitoring of patients, the number of circulating tumor cells, detection of genetically modified organisms, food allergens and pathogens. Among biological entities, DNA copy number or cell number are commonly used quantities. However, the lack of a reference method and/or material for the determination of these quantities is a major challenge in this field. Therefore, this poses a significant problem in ensuring traceability in the measurement of biological molecules and entities. To address this problem, the Bio-SITrace project aims to achieve a high degree of traceability in biological measurements using two key techniques: the application of purified calibration materials and the use of counting techniques.

When the electrical signal is digitized with data converters, the effective value, peak value and harmonic components of the signal can be calculated from the digital data obtained. Advances in precision whole circuit fabrication technology have given data converters a step up in sampling rate and accuracy. However, the established AC voltage metrology, which only determines the RMS value of the signal, cannot meet the needs of digital metrology. The aim of this project is to establish direct traceability to a quantum voltage standard based on the Josephson effect for AC voltages, so that testing of data converters can be performed in line with the needs of digital metrology.
TÜBİTAK UME is in this project:

The acoustic properties of technical products such as refrigerators, washing machines, vacuum cleaners, etc. are given in terms of sound power. Since there is no standard and procedure for the direct measurement of sound power, the experimental determination of the sound power levels of the products is made through sound pressure level measurements. Sound power can be calculated from sound pressure data measured by limiting only certain parameters in the test setup. There is more than one standard for the determination of sound power. The lack of harmonization between these standards results in both different calculated sound power values and uncertainties in sound power measurements in single digits greater than one dB. As a consequence, it becomes impossible to resolve the contradictions between the legal requirements defined for noise protection and measurement results. The aim of this EMRP-JRP research project is to ensure the traceability of the sound power unit size, Watt, and to eliminate the problem of discrepancies in different sound power results.
There are 5 work packages (WPs) in this project.
- The primary reference standard in work package IP1 involves the development and validation experiments of a sound power source on its foundation using a vibrating plate.
- IP2 includes research and measurements to be carried out for the dissemination of the sound power unit through an appropriate transfer standard to be determined.

- IP4 includes activities on the widespread impact and added value of the JRP.
- IP5 is the project management work package.

Apart from this, it has been involved in all other work packages in order to perform research and measurements. As a result of this project, a primary level reference sound power source will be manufactured and installed at UME and each of the other participating institutes. By using primary level sound sources, the sound power unit will be disseminated to secondary level laboratories and industry through the transfer standard and thus the traceability of the sound power unit will be ensured through the developed reference standard.

With this project, the construction and development of advanced industrial magnetic sensors and the calibration and testing of the final product will be carried out within the scope of metrology study. The project aims to develop measurement techniques for the construction, development and testing of advanced magnetic sensors, expand the traceable calibration range of advanced magnetic sensors to meet current and future needs, develop metrological instruments for the traceable characterization and industrial testing of spin torque sensor materials and devices, develop procedures for the validation of micromagnetic simulation instruments to be used in sensor development, and develop metrology for the characterization of future advanced magnetic and spintronic sensor concepts.
In this project, TÜBİTAK UME is investigating the internal magnetic structure of thin magnetic films used for AMR sensors using the magnetooptical system.
The use of DC power transmission lines at medium and high power levels is increasing worldwide. Various measurements on the DC side of the transmission system have been performed for a long time. However, the metrological infrastructure on which these measurements are based cannot fully meet the needs. The technological developments that have emerged with the advancement of the metrological infrastructure are not reliable enough to determine the power losses of the converters in the transmission lines, to monitor the line voltage, to control the power quality and to ensure the accuracy of billing transactions. For this reason, in 2010, 7 European Metrology Institutes, including TÜBİTAK UME, a university and an industrial organization came together and started a research project supported by the European Union within the scope of Article 169 in order to overcome the deficiencies mentioned above. With this project, not only the traceability of all HVDC systems with a voltage level of 1000 kV will be ensured, but also the devices that will allow various calibrations and measurements to be taken even in HVDC centers in the field. In Europe, DC high voltage traceability is provided with very good accuracy up to 300 kV and with less accuracy up to 400 kV. Above 400 kV there is no traceability. For 800 kV HVDC systems there is a very significant traceability problem.
TUBITAK UME is actively involved in many aspects of this project, especially the design, construction and characterization of the 1000 kV DC high voltage divider, and is partnering with the most important goal of this work. This purpose; As the High Voltage Laboratories of the National Metrology Institutes operating in Europe, the calibration of HVDC stations under maximum voltage is provided in the field (on-site), in the manufacturer's factory or in laboratory environments. In addition, with the system created, the need for ripple and harmonic measurements, which are very important in studies on the power quality of HVDC stations, will be met.
The use of renewable energy sources such as biofuels is encouraged for energy efficiency. However, the analysis of biofuels also needs to be reliable and comparable in the long term. This EMRP (European Metrology Research Projects) Project aims to determine the chemical and physical properties of biofuels with the participation of eight metrology institutes and three university laboratories and to prepare the ground for the production of certified reference materials.
The main objective of this project is to assure the quality of alternative EMC test methods that are mandatory and not based on any standard for large/complex or high electrical power demand devices/systems in industrial environments and also for small sized devices. This project will first focus on the characterization and development of alternative EMC methods that are currently used in industry and are not based on any standard, and then a strong link will be established between these alternative methods and the standard methods applied in laboratories. In addition, the design of new alternative test methods in line with the needs of the industry will also be realized in the project. The total number of work packages of the 10-partner project, which includes metrology institutes and universities from Turkey, France, the Netherlands, Spain, Slovenia, Slovenia, Czech Republic, Sweden and Switzerland, is 7 and the total project duration is 3 years.
Approximately % 40 of the total workforce in the project consortium will be provided by TÜBİTAK UME. TUBITAK UME takes an active role in all work packages and tasks of the project in the test areas of transmission propagation, transmission immunity, radiation propagation and radiation immunity. In addition, as the coordinator, TUBITAK UME will be responsible for all the impact and management of the project to the industry. This is of great importance for our institute to become a center of excellence in the field of EMC.
The JRP SIB58 Angles - Angle Metrology Project is funded by the European Metrology Research Program (EMRP) and will run from September 2013-2016. The project consists of 16 consortium partners, including advanced national metrology institutes, manufacturers and research institutions working in the field of angle metrology: TUBITAK UME (Turkey), CEM (Spain), CMI (Czech Republic), INRIM (Italy), IPQ (Portugal), LNE (France), MG (Poland), MIKES (Finland), PTB (Germany), SMD (Belgium), AIST (Japan), FAGOR (Spain), KRISS (Korea), MWO (Germany) and HZB (Germany).
Angle metrology is a key technology for high value-added science and industry in which Europe can compete globally. Examples of applications of angle metrology include precision shape measurements of optical surfaces (radiation guiding optics in accelerator and free electron laser centers, reference optics used in interferometers); precision manufacturing engineering (geometry of moving mechanisms, measurement of linearity, planarity and parallelism parameters); industrial applications (automotive, robotics, automation, aerospace); scientific applications (gravitational acceleration measurements, angular stability of x-ray optical accents). For the new angle measurement devices and standards recently developed, there are significant challenges in the above-mentioned application areas. For this reason, characterization and calibration of autocollimators, which are angle measuring devices, for advanced applications with sub-nanometer form precision, development of new types of self-calibrating smart angle encoders, angle encoders and small angle generators, and angle production at the nrad level with angle encoders and small angle generators, traceability to the SI angle unit radians must be guaranteed.
The project will be led by Assoc. Prof. Tanfer YANDAYAN from TUBITAK UME. The project is expected to advance angle metrology beyond the current technology with scientific and applied studies to develop prototype devices that are traceable to the SI angle unit radians and can operate with an extended uncertainty of 0.01" (50 nrad). With this study, it is aimed to make SI traceable angle measurements in industrial applications and to guarantee the traceable application of angle measuring devices in scientific studies. Detailed information (www.anglemetrology.com) can be obtained from the project website.
EMRP is co-funded by EMRP participating countries in EURAMET and the European Union.
TÜBİTAK UME currently produces various certified reference materials. When this project with a budget of EUR 3 million is completed, the existing certified reference material (SRM) production infrastructure of our institution will be further strengthened and will continue to contribute to the national economy.
Taral Projects
The project is a TUBITAK supported bilateral research project with foreign partners. It aims to develop an international standard measurement system for gene methylation measurements in collaboration with metrology institutes in Turkey and South Korea. Gene measurements have started to be used in early diagnosis of cancer.
With this project, certified reference material (SRM), low and high level calibrators and controls will be produced and certified for amino acid and organic acid analysis in plasma and urine samples for newborn screening and routine analysis.

The SRM, calibrators, controls and deuterium isotope standards to be turned into products will be the first domestic products to be produced in this field in our country, and will both meet the needs of hospitals in our country and provide foreign currency inflow to our country through exports to abroad.
The scope of the project is the design and robust production of 0.1S class current and 0.1 class voltage transformers and combi sensors for the first time in our country. With the project, it is aimed to improve existing products, to produce innovative products, to prevent waste and losses in the production process with the new production technique and to reduce costs, and to avoid the need for additional laboratory space, personnel or systems with the functional laboratory devices to be designed.
In this project, classroom design models will be developed that offer more suitable learning environments for hearing impaired students.
Project Scope:

Evaluating the effects of classroom designs on speech intelligibility in combinations of ringing time and signal-to-noise ratio and developing design recommendations based on the subjective scores obtained
Within the scope of this project, it is aimed to develop a robust magnetometer that can measure DC field magnitudes from extremely low magnetic field magnitudes such as 10-⁹ Tesla to the level of the Earth's magnetic field (0.5 × 10-⁴ T), can be used in all kinds of satellite missions (700 km, 27,000 km and 50,000 km orbiting satellites), and has passed temperature, radiation, vibration and vacuum tests.
The targeted magnetometer is based on the principle known in the literature as Fluxgate. The most critical component that determines the sensitivity and noise level of such magnetometers is the sensing core. The production of these cores, which have a soft magnetic and glassy structure, requires a high level of intellectual knowledge and experience. These cores, which can only be supplied by two companies in the world, are critical components that are sometimes not even quoted due to their strategic application areas.
The scientist who produces the highest quality cores in this field is Dr. Peter Svec from Slovakia. Dr. Svec is a well-known name in his field, having authored over 200 scientific papers and received numerous citations. Researchers developing fluxgate magnetometers often work with Dr. Svec for the supply of cores.
Within the scope of the bilateral cooperation with Dr. Svec and his team, the project aims to transfer knowledge on the core production process and to develop production capacity with national facilities. At the end of the project, it is planned to bring the most suitable magnetometer design for satellite and other applications to the domestic industry and to encourage its use. Thus, it is aimed to pioneer the participation of Turkey in the global magnetic sensor market, which is worth 2 billion dollars.

To develop a femtosecond Yb-doped fiber frequency comb system compared to the Ti:Sa frequency comb and to use it in metrology applications.
They came out:
1. Design and construction of a portable small-scale Yb-doped fiber laser (YDFL).
The designed temperature-controlled Yb fiber laser (figure 1.1) has a repetition frequency of 100 MHz and an output power of 250 mW. The repetition frequency of the frequency unlocked laser varied less than 0.8Hz in the 10000 s time interval. The repetition frequency stability was measured to vary between 2×10-10 - 6×10-10 in the time range of 1 s and 2000 s with ambient.
2. Noise analysis of the irradiance of a Yb-doped fiber laser.
The spectrum of the laser intensity noise measured in the frequency range 3 Hz - 250 kHz and the RIN values corresponding to 1 Hz bandwidths are given in Figure 2.1. As can be seen from the figure, the noise is mainly active in the region below 1 kHz.
3. Analysis of the phase noise of the repetition frequency signal of a frequency-locked Yb-doped fiber laser.
The phase noise is -103 dBc/Hz at 1 kHz, decreases with increasing frequency and approaches the noise floor of the measurement system at 30 MHz. When we analyze the phase noise results (figure 3.1), the time shift of the pulses in the investigated time interval is calculated as 41 fs
4. The repetition frequency of the Yb-doped fiber laser is locked to the reference 10 MHz signal of the Cs atomic clock.
The block diagram of the experimental setup is shown in Figure 4a and the average time dependence of the laser stability is shown in Figure 4b. The pulses of the laser were detected with a photodetector to generate an RF signal and the frequency of this signal was locked to the 10 MHz signal of the Cs atomic clock using a phase locking electronic system. With this method, the stability of the free-running laser between 10-9 -10-10 was brought to the atomic clock stability (10-11 - 10-14).

Semiconductor nanoparticles with optical properties that depend on particle size are called quantum dots. Their size usually varies between 2 and 10 nanometers. In a quantum dot (example: CdS), the movement of electrons is limited and the energy levels are packed. As the particles get smaller, the forbidden energy range widens, and the size-dependent forbidden energy range leads to a wide range of applications. There are many application areas such as solar cells, LEDs, light sensors, lasers, medical imaging, optical marking. This project aims to synthesize nanoparticles with both magnetic and luminescent properties by attaching Fe3O4 molecules with superparamagnetic properties to CdS molecules with semiconductor properties. In order for quantum dot and superparamagnetic properties to be seen together, the final particle sizes will be smaller than 10 nm. This will pave the way for the use of these particles in drug delivery systems used in cancer therapy and in the image clarification process in MRI imaging systems.
In this project, TÜBİTAK UME takes an active role in the determination and scientific evaluation of the magnetic behavior of nanoparticles.

Externally Supported Projects
The project, which was entitled to receive support within the scope of the Eastern Marmara Development Agency (MARKA) Combating Covid-19 and Resilience Program and carried out by TÜBİTAK UME, was successfully completed in a short period of 3 months and SARS-CoV-2 RNA Reference Materials were produced.
The RNA reference materials produced will be used in method development studies to increase the accuracy of PCR-based tests performed in clinical laboratories and as internal quality control materials in SARS-CoV-2 PCR kits produced in our country. Since the quality control materials in existing kits are DNA-based, the conversion step of RNA to cDNA cannot be controlled. The use of RNA Reference Materials will increase the accuracy of PCR-based SARS-CoV-2 measurements in our country. With the infrastructure developed in TÜBİTAK UME laboratories and the technical experience gained, new RNA reference materials can be produced in a very short time in case the SARS-CoV-2 virus mutates or another virus emerges.

In this project, a similar system was developed for the Macedonian Institute of Metrology, installed on-site, provided the necessary training and BOM started to distribute national time using this system via the "time.bom.gov.mk" address.
Upon the request of Çanakkale Seramik A.Ş., a pulse high voltage recorder device with precise accuracy was built to be used in the routine tests carried out in the high voltage test laboratory of the company.
The aim of this project was to carry out technical studies on the restructuring of the Macedonian Bureau of Metrology (BoM), which was carried out between May 20-23, 2007 with the support of the Turkish Cooperation and Development Administration (TIKA).
With the 5-year contract signed between TÜBİTAK UME and OPET Petrolcülük A.Ş. on 20.05.2014, it was aimed to develop and establish a Company Marker system for OPET Petrolcülük A.Ş. Within the scope of the project, the production of Company Marker for gasoline and diesel types and control devices for field inspections were realized at TÜBİTAK UME, and a complete system was established with devices and remote monitoring software. Every stage of this system has been developed domestically with TÜBİTAK UME's own facilities and capabilities. TÜBİTAK UME continues to work equally with all companies in the fuel sector to produce the solutions they need. Within the scope of the project, TÜBİTAK UME produces Company Marker and delivers this marker to OPET authorities once every 2 months, provides technical support and calibration services for field inspection devices designed to be used in field inspections, and ensures that the results are monitored "online" by providing interactive access to the central database at TÜBİTAK UME by persons designated by OPET.

Customer Supported Completed Projects
Microcalorimetry is considered the primary level system for RF power measurements and is used by national metrology institutes to calibrate power sensors used for primary level power measurements. These systems are not commercially available, but are produced as part of projects by major metrology institutes such as NPL (UK), PTB (Germany), LNE (France), INRiM (Italy) and NIST (United States). Microcalorimeters are custom-designed by the institutes to meet their requirements, with different designs for each connector type and power sensor.
Within the scope of the N-Type Microcalorimeter Development Project for the Egyptian Institute of Metrology (NIS), the microcalorimeter system, which was completely realized by TÜBİTAK UME RF and Microwave Laboratory, was officially completed and delivered to the user on turnkey basis.
Within the scope of the project, the design, production and functional testing of an N-type (10 MHz-18 GHz) microcalorimeter was successfully finalized through RAMNT company, and the training was provided and made available to the Egyptian Metrology Institute.
With the completion of this project, the primary level microcalorimetry system was realized entirely using the capabilities of TÜBİTAK UME and Turkey and was made available to another country's metrology institute.
The extraction, processing and utilization of boron mines, which are an important natural resource for our country, by transforming them into high value-added products are among our national priorities. The ground form of colemanite, a boron ore, is produced by Eti Maden İşletmeleri and sold in line with certain quality standards.

UME Supported Projects
Conductivity is a measure of the ability of a solid, liquid or gaseous substance to conduct electric current. In solutions, conductivity is provided by positively or negatively charged ions and this type of conductivity is called electrolytic conductivity. Electrolytic conductivity measurements and control are of great importance both in research studies applied in fields such as chemistry, medicine, food and environment in industrial processes and in determining the compliance of a product with legal requirements. Conductivity measuring devices are used in all these measurements. Certified reference conductivity solutions (SRM) are used for the calibration of these devices used in all public, private and university laboratories in Turkey and these materials are supplied from abroad. Therefore, it is planned to produce and certify these solutions within the country. In this way, it is aimed to keep the foreign currency spent in previous years in our country by obtaining reference solutions from foreign sources domestically.
Today, ultraviolet radiation is used in applications ranging from medical therapy to phototherapy. The Optics Laboratory has been providing calibration services in the ultraviolet region for many years only in the far ultraviolet region (UVA, 315 nm - 400 nm wavelength range) for the measurement devices (radiometers/spectroradiometers) and total/lobal Radiation Level Sensitivity of radiation sources. When the applications received in recent years are analyzed, it is seen that there is a demand for calibrations of measuring instruments or radiation sources used in the mid ultraviolet region (UVB, covering the wavelength range 280 nm - 315 nm).
It is also aimed to reduce the calibration time (UV-A and UV-B radiometers/irradiation sources) with the computer-controlled measurement system.
Therefore, this project aims to build a reference UV-B Radiometer and calibration infrastructure to provide radiation level calibration services in the UV-B region.
In order to contribute to new studies on the scale of ITS-20XX and to keep up with the innovations, this project aims to characterize the new fixed points defined in ITS-90, which are not defined in ITS-90 but are foreseen to be studied within the scope of scientific studies and EMPIR projects.
Investigation of the temperature/humidity dependence of very high value reference resistance standards
With the establishment of the dynamic force calibration system, TÜBİTAK UME will be able to respond to the need for traceable force measurements in this context in our country.
In TUBITAK UME Pressure Laboratory, cross-float method is used in the calibration of piston pressure standards. However, this method is being improved by using various methods in the field of pressure metrology due to operator dependency and long calibration time. In this way, operator dependency is reduced, calibration time is shortened and the reliability of the measurement is increased.
With this planned project, it is aimed to increase the reliability and efficiency of measurements made in the pressure field and to reduce operator-related errors by improving the automation of piston pressure standards and cross-float method.
The aim of the project is to extend the frequency range of the reference AC high voltage measurement system in TÜBİTAK UME high voltage laboratory. While the frequency range of the current AC high voltage measurement system is 45-60 Hz, this project will provide a reference measurement system infrastructure with a frequency range of 40-300 Hz. In addition, very low frequency (VLF) AC high voltage measurements, which are becoming widespread today, are also among the objectives. In this project, the frequency range of the EDF AC high voltage measurement system is defined as 0.01-0.1 Hz.
With this project, it is aimed to make an LED-based collection sphere source with adjustable optical emission spectrum, which will be a reference device for metrological spectral determination of the optical properties of optical imaging cameras and new generation information/display screens (LED, OLED, etc.) used in today's technologies. By this means, the lack of calibration service of the laboratory in this direction will be eliminated and at the same time, the existing service scopes (Luminance, Color Temperature and Color coordinates) will be expanded. The optical emission source to be designed within the scope of the current project and the knowledge to be gained will be useful and guiding for the EMPIR SRT s11 - "Future photometry based on LED technology" project, which we have been accepted as a project partner in the 2018 calls.
Today, the rapid development of wireless communication technologies and the discovery of many application areas have made high frequency systems a part of our lives. 3G, 4G, 4.5G and in the near future 5G mobile phones, Internet of Things (IoT) applications, Machine to Machine M2M (Machine to Machine M2M) in production facilities and autonomous cars that do not require a pilot are technologies that use high frequencies that have recently entered or are entering our lives.
While 5G technology in Mobi+C21l phones envisages the use of 60 GHz - 80 GHz carrier frequencies in highly populated living centers, autonomous cars envisage a magnetic field control at 100 GHz frequencies covering the entire vehicle instead of a multi-sensor system. In M2M communication, which is rapidly increasing with Industry 4.0, it is mentioned in many sources that 110 GHz will be widely used in the medical and automobile radar and transportation vehicles sector in the next 10 years [1, 2, 3].
The rapid increase in the number of RF communication devices and the frequencies they use increases the need for RF power and S-parameter (reflection and transmission coefficients) measurements and traceability requirements. The increase in the communication frequency up to 110 GHz makes it mandatory to perform these measurements at least at 110 GHz.
Today, advanced metrology institutes such as PTB-Germany, NPL-UK, METAS-Switzerland and LNE-France are developing their infrastructure to meet this need and have solved measurement and traceability problems up to 110 GHz.
Institutes such as NPL and PTB have solved measurement and traceability problems at frequencies up to 110 GHz, and have largely extended the frequency band up to 300 GHz and are working to go even higher. Similarly, in the last two years, the scope of the major projects opened within the scope of EMPIR in the microwave field is for frequencies above 110 GHz, and it does not seem possible for TÜBİTAK UME RF and Microwave Laboratory to take part as an important partner in these new projects with its existing infrastructure.
TÜBİTAK UME's Time Frequency Laboratory has a 170 GHz frequency measurement structure and the Voltage Laboratory has an RF system operating at 75 GHz - 90 GHz in Josehson's Junction system, The Temperature Laboratory has a 20 GHz S parameter measurement system and the newly established Quantum Metrology Laboratory has 110 GHz power and S parameter test systems. In addition, the power and S parameter measurement systems in the infrastructure of the RF and Microwave Laboratory, which was established in 1996, have a frequency range of 100 kHz - 50 GHz.
This project has been prepared in order to make the RF and Microwave Laboratory, which provides services within the scope of RF power and S-parameters both to the industry of our country, which produces RF-based production, and to TÜBİTAK UME laboratories (Time and Frequency Laboratory, Temperature Laboratory, Voltage Laboratory, Quantum Metrology Laboratory), which create national standards with RF systems, ready for calibration and measurement services at frequencies up to 110 GHz, which will be requested in a few years, and to meet the demands for material characterization up to 170 GHz.
TÜBİTAK UME Power and Energy Laboratory operates in AC Power and Energy measurements, AC High Current Ratio and Phase measurements and AC High Voltage Ratio and Phase measurements. AC Power and Energy measurements and AC High Current Ratio and Phase measurements are traceable to national standards. The traceability of AC high voltage ratio and phase measurements is ensured at a secondary level with the calibration of the multi-ratio voltage transformer used as reference by PTB.
In this project, it is aimed to develop reference devices used in AC high voltage ratio and phase measurements. For this purpose, a high accuracy reference voltage transformer will be designed and manufactured.
In order to ensure the traceability of both newly manufactured and existing reference voltage transformers in the laboratory to national standards, a primary level measurement system using the "Current Comparative Capacitance Ratio Measurement" method, which only a few metrology institutes abroad have, will be established.
Nowadays, in many measurement and control processes, it has become necessary to be able to measure time-varying parameters. For this purpose, the main objective of this project is to make dynamic pressure measurements traceable to SI (International System of Units) units in our country by using the device and method to be developed with this project.
Since 2003, EMC tests of military devices produced by companies such as TÜBİTAK SAGE, ASELSAN, ROKETSAN, HAVELSAN with national facilities have been carried out by our laboratory and more than 2000 certificates have been issued. As a result of this intensive use, some of our test devices/systems started to malfunction frequently, and the repair time of these test devices/systems took very long periods of time due to reasons such as the long supply of spare parts or the unavailability of spare parts. Due to the aforementioned reasons, EMC testing in our laboratory has been seriously disrupted and even stopped from time to time. In addition, our test equipment/systems, which were purchased according to the test requirements of 15 years ago, can no longer fully meet the requirements of the new EMC standards such as harmonic level, modulation types, etc. with the revision of military and civil EMC test standards.
UME EMC laboratory also performs the calibration of many measurement devices used in EMC tests and electromagnetic field measurements. Since the devices used in EMC tests are also used in the calibration of customer devices, our customers who apply for calibration are given advanced dates, which interrupts the work of our customers who perform EMC tests.
In the field of EMC, Reverberation Chambers have been used in recent years, especially for high electric field test applications, and it is thought that many military and civilian products will be tested in Reverberation Chambers in the coming years. Due to the intensive use of the test systems/devices in our laboratory, there is not enough research and study on this field. In addition, Time Domain measurements, which have been touted as the measurement technology of the future in the EMC world for the last few years, which are thought to enable on-site measurements by taking into account ambient noise, which are very fast and at low costs compared to the prices of traditional EMC test systems, cannot be started due to lack of infrastructure, and limited tasks are taken in EMPIR calls opened in this field.
It is aimed to establish a PVTt system with very good uncertainty in UME gas flow measurement and to provide traceability to the entire flow range.
The main objective of this study is to produce phantoms, which are used as reference materials for quality control and performance testing of ultrasonic imaging devices. In addition, a measurement system for determining acoustic parameters will be developed within the scope of this project.

- National and international publications
- Participating in research on different measurement capabilities with original "Blackbody Cavity" designs in the future
As a result of the scientific and technological revolution and due to the ease of life they provide, electrical devices and communication tools that have gained a permanent place in our lives have harmful effects as well as benefits. All these devices are sources of electromagnetic pollution and this pollution has become a part of our lives. Our country first met electromagnetic pollution with high voltage lines. In the 1990s, the process continued with the granting of broadcasting permission to private radios and televisions. With the introduction of cell phones, the establishment of base stations began to attract people's attention as electromagnetic field pollution reached a more risky level.
Electromagnetic fields cannot be perceived by sensory organs, but can only be evaluated by measurement. The measurement results are evaluated according to international (ICNRP - International Commission on Non-Iozing Radiation Protection [1,2]) or national limits that are considered to be harmless to human health.
The Ministry of Environment has also issued a circular to regulate electromagnetic pollution in our country and to specify limit values. This circular (the "Regulation on the Determination, Control and Supervision of Exposure Limit Values of Electromagnetic Field Intensity Arising from Electronic Communication Devices According to International Standards" published in the Official Gazette dated April 21, 2011 and numbered 27912 [3]) provides information on the limit values of electromagnetic field pollution of the environment and a single device.
NRPB (National Radiological Protection Board) [1,2], a scientific organization of the British Government, uses highly sensitive systems and measurement methods to determine the electromagnetic pollution level emitted by a single device. Due to the circular issued in Turkey, there is a need to accurately measure the level of electromagnetic pollution emitted by a single device. This study is proposed to establish the NRPB system or a similar system.
With this project, a comparison system that can perform capacitance comparison in the range of 1 pF - 100 nF and AC resistance comparison in the range of 10 kΩ - 2 MΩ up to a frequency of 10 kHz will be produced.
The frequency stability and accuracy values achieved by atomic frequency standards in the last fifty years have made them indispensable devices for the establishment of SI units and universal physical constants, communication, navigation and timekeeping systems. For example, the frequency stability and accuracy of the atomic frequency standard installed in communication satellites determine the uncertainty in position determination, while the frequency standard used in communication systems must be synchronized and syntonized.
In the proposed project, 1 "Pulse Optically Pump (POP) Based Rb Atomic Clock" and low energy
1 "Rb Atomic Frequency Standard" laboratory prototype, which is small in volume and compatible with satellite positioning systems, will be realized. In addition, in the proposed project, an Er-doped mode-locked fiber laser operating at 1550 nm wavelength with low phase noise, an external
"Photonics Based Rb Atomic Clock" scientific research will be realized with the use of cavity diode lasers, dielectric resonator and Sagnac interferometers.
Diabetes is a metabolic disorder caused by hereditary and environmental factors, resulting in excessively high blood glucose levels (hyperglycemia). According to data from the World Diabetes Foundation, the number of diabetes patients worldwide is estimated to reach 438 million in 2030. There are currently 5 million diabetics in Turkey. This number has been found to increase by 6 percent every year. Hemoglobin A1c measurement (HbA1c) is a blood test used both to diagnose diabetes and to measure the effectiveness of diabetes treatment. It has become increasingly used in diabetes treatment as it provides information about the past blood glucose profile.
In our country, both public and private clinical laboratories diagnosing diabetes procure certified reference materials for HbA1c measurements from abroad. For this reason, this proposed project aims to produce certified reference materials to be used in HbA1c determination, taking into account the country's priorities.
It is very important that the national time scale used in critical applications operates without interruption, reliably and traceably. UME Time and Frequency Laboratory has 5 high performance tube Cs atomic clocks for the creation of the national time scale, but the national time scale is obtained using only one atomic clock. The other atomic clocks are kept in the system for backup purposes in case of any risk scenarios. With this structure, the system carries some risks such as reduced reliability and interruption of traceability.
With this project, it is planned to create a more accurate weighted time scale with better stability and reliability than individual Cs atomic clocks by taking the weighted average of 5 existing Cs clocks. At the end of the project, a real-time national time scale and algorithm is targeted.

In this project, it is planned to prepare and certify primary reference gas mixtures at various concentration ranges for component gases (methane, ethane, propane, i-butane, n-butane, i-pentane, n-pentane, hexane, hydrogen, helium, carbon dioxide and nitrogen) which have an important place in natural gas measurements. At the end of the project, approximately 15 primary gas mixtures will be prepared and reference material preparation and analysis services will be provided for these gases. In addition, this project i) to participate in the comparisons related to natural gas analyses included in the comparison list planned to be organized by BIPM GAWG between 2013-2023, ii) to ensure the traceability of private gas producers, distribution companies and private or public laboratories performing gas analysis through TÜBİTAK UME with the preparation of primary reference gas mixtures, which is the primary task of the Gas Metrology Laboratory, and iii) to meet the demands of other country national metrology institutes, which are newly established or to be established, regarding the preparation of primary gas mixtures or the establishment of the relevant infrastructure.
A primary level measurement system for electrolytic conductivity measurements will be installed.
With the system to be established, participation in international comparisons and projects will be realized and conductivity measurements will be harmonized with the SI units system. Traceability for these measurements will be provided through TÜBİTAK UME.
In the member countries of the Standards and Metrology Institute for Islamic Countries (SMIIC), species determination of meat and meat products is carried out in public and private laboratories. In these determinations, reference materials are used to ensure measurement quality and these materials are supplied from abroad. In this project, reference materials will be produced for the determination of pork species in meat and meat products.
Carbon dioxide and other gases released into the atmosphere as a result of the intensive use of conventional energy sources cause environmental pollution, global warming and climate change by creating a greenhouse effect. For this reason, in the project calls made by the European Union (EU) in recent years, it is seen that in addition to the research and development studies to be carried out in these fields, especially measurement methods and techniques are of great importance in terms of making future projections by modeling energy consumption and climate changes and taking measures in these issues. When the measurement techniques in these fields are examined, it is seen that optical measurement methods are of great importance, and studies on the research of optical properties such as radiation, reflection and polarization of instruments used in space observations, energy and climate changes are increasing rapidly. In parallel with the developments in the world, the need to develop the infrastructure for new needs arises in our country. For this reason, in this proposed project, it is planned to establish a monochromator-based high-resolution spectroradiometer system, to obtain the radiometric measurement unit of radiation sensitivity and to establish a traceability chain, as well as to improve the existing service quality in the field of optical radiometry and at the same time to conduct research on the aforementioned optical characterizations of instruments used in fields such as energy, health and environment.
In order to realize the protection of ground and surface waters and prevention of water pollution in line with sustainable development goals, it is of great importance to keep wastewater discharges under control in line with the water pollution regulations implemented by the countries. Pursuant to Directive 91/271/EEC of the European Union and Directive 2013/39/EU in force in relation to this Directive, certain limits have been introduced for the discharge of urban wastewater. In our country, with the directive published by the Ministry of Environment and Forestry in the Official Gazette dated 31.12.2004 and numbered 25687, limitations have been imposed on the pre-discharge wastewater values specific to various industrial industries in order to prevent and sustain the pollution of the groundwater and surface water resources of the country. As in other countries, wastewater matrix reference material, which is needed to ensure the reliability of the analyzes carried out for this purpose in our country, is produced by very few metrology institutes or similar organizations in the world. The aim of this project was to fill this gap in both national and international markets.
Scientific and technological advances in the last 50 years have led to major changes in measurement science. Newly discovered stable microscopic quantum processes and macroscopic quantum effects (AC Josephson voltage, Klitzing resistance, etc.) have made measurements with very high accuracy possible. As a result of these developments, the classical definitions of physical quantities and their units in the metric system have come into conflict with the modern scientific view. The need for change and development of the international metric system (SI) has emerged.
The watt balance experimental setup plays an important role in this process of change in the SI. The extremely high complexity of existing watt balances (NIST, NPL-NRC, METAS, BIPM, LNE, KRISS, MSL) not only limits the accuracy of Planck's constant measurements, but can also cause serious problems in the realization of the kilogram at national metrology institutes. Unlike conventional watt balances, the "oscillating magnet-stationary coil" experimental setup developed at UME has very low complexity. High accuracy, small size, low cost, easy operation and maintenance are important advantages of this experimental setup. The first stage goal of the UME watt balancing project is to reach NIST-1 watt balancing performance, and then it is aimed to achieve better results than the METAS 2012 results.
In this project, the preparation and certification of primary reference gas mixtures in all concentration ranges for carbon monoxide and carbon dioxide gases, which play an important role in air quality measurements, are planned. At the end of the project, these gas mixtures will be prepared and reference material preparation and analysis services for these gases will start to be provided. Also with this project; In the 2013 EMRP project "SRT-v04 Metrology for high-impact greenhouse gases", the activities in the work packages in which the Gas Metrology Laboratory is involved will be realized, With the preparation of primary reference gas mixtures, which is the primary task of the Gas Metrology Laboratory, the traceability of the calibration gases required by public and private organizations related to the measurements of air quality and the mixtures prepared by private gas producers will be ensured through TÜBİTAK UME, and finally, it will serve to meet the demands of the national metrology institutes of other countries regarding the preparation of primary gas mixtures or the establishment of the relevant infrastructure.
There is an increasing industrial demand for calibration of thermocouples at high temperatures (up to ~1500 °C). In order to add the 1300 °C / 1500 °C region to the thermocouple calibration capacity of our laboratory, the construction of a copper fixed point (1084 °C) and iron-carbon (1153 °C), cobalt-carbon (1324 °C) and palladium-carbon (1492 °C) eutectic points suitable for thermocouple measurements is planned. This work is also important for participation in the international benchmark on "High-temperature calibration of thermocouples" scheduled to start in 2013.
The subject of the project is the computer-controlled determination of the density of the lifting fluid using automatic alignment and reference density standard (sinker) for the calibration of the scale lines of hydrometers. The main element is the improvement of the laboratory primary level standard, eliminating the disadvantages of the current system and ensuring fast, efficient and highly accurate results.

It is aimed to produce a reference material that certifies properties such as cold filter plugging point (CFPP), flash point, distillation, cetane index, density, kinematic viscosity and water content in diesel fuel type.
Sulfur compounds are present in the structure of almost all petrochemical products and the determination of total sulfur content is an important part of the quality control process in petrochemical laboratories. Sulfur emissions from fuel combustion are one of the leading sources of environmental pollution. Directive 2003/17/EC of the European Parliament and the European Council has lowered the upper limit of sulfur content in gasoline and diesel fuels to 10 mg/kg as of January 2005. Laboratories need to check the accuracy of their measurements for quality control purposes. Many certified reference materials (SRMs) for quality control are commercially available. Given the short shelf life and frequency of use of such SRMs, quick and easy availability of the material is important for petrochemical laboratories in Turkey.
In this project, the design and manufacturing of reference gas calorimeters in accordance with ISO 15971:2008 'Natural Gas - Properties of Measurement - Calorific Ratio and Wobbe Index' standard, solid and liquid reference calorimeters in accordance with TS 1740 2006 'Liquid Hydrocarbon Fuels - Determination of Heat of Combustion - Calorimeter Bomb Method' and ASTM D5865-2013 'Test Methods for Thermal Values of Coke and Coal' standards will be realized.
The construction of all three reference calorimeters is based on the same principle. While the combustion chambers of the solid and liquid calorimeters are made of stainless steel material and their interior parts need to be polished, the combustion chamber of the reference gas calorimeter is made of glass. With these reference calorimeters, the amount of heat energy generated by the combustion of solid, liquid and gaseous fuels can be measured at the international level.
Thanks to this project, the thermal values of certified reference materials with international traceability will be calculated precisely with the information obtained through experimental studies and the necessary certification procedures for the measurement of thermal values will be carried out with the calibration methods to be developed. In addition, it will pave the way for the scientific and technological studies we need on the calculation of thermal values.
pH measurements are one of the most widely applied measurement techniques. The accuracy of pH measurements applied in the health, environment, food and chemical sectors is also important for our daily lives. The requirement for accurate pH measurements is the calibration of the pH system. As a result of the calibration process, two performance parameters of the glass electrode are determined. Since the stability of the glass electrode is short-term, it needs to be calibrated frequently. Currently, the standard buffer solutions used in all these calibrations are imported from abroad and traceability is ensured from abroad. Another problem is the long lead time for these products (4-8 weeks).
Within the scope of the project, buffer solutions with different pH values (4, 7 and 10) will be prepared. In this way, traceability for pH measurements will be ensured through TÜBİTAK UME and the standard solutions required for pH measurements will be supplied domestically and dependence on foreign countries will be reduced.
Fuel markers recently produced by the chemistry group glow in the infrared region. The fuels themselves absorb very little infrared light and emit very little fluorescence in this region. These properties of the materials allow for a precise and simple measurement of the marker concentration in the fuel using fluorescence spectroscopy. For this reason, a fluorescence spectrometer operating in the infrared region was built within the scope of the project. The system is not a general purpose fluorescence spectrometer, but is specifically designed for marker measurements in order to be more compact and inexpensive.
Lasers, which are widely used in various sectors such as health, communication, space and defense, are divided into two groups as continuous and pulsed mode lasers according to their radiation pattern. In our country, continuous mode laser measurement needs can be met with the infrastructure established in the UME optics laboratory. However, due to the lack of the necessary infrastructure for pulsed mode laser measurements, the demands in this field cannot be met, and only the calibration needs of the Turkish Armed Forces at 1064 nm wavelength can be met with measurement systems that are traceable to international metrology laboratories. With this proposed project, it is aimed to establish the reference standards required for pulsed mode laser (Q-switched) measurements, which have a wide range of applications, traceable to UME primary level measurement standards, and to provide pulsed laser measurement services to institutions and organizations throughout the country domestically.
In order to minimize the possible effects of electromagnetic waves emitted by mobile phones during their use, many international standards have been established for mobile phones. In international standards, the Specific Absorption Rate (SAR) value is the main parameter for mobile phones and SAR limit levels are defined in international standards. The aim of this project is to perform SAR measurements of mobile phones at 300 MHz, 450 MHz, 900 MHz, 1800 MHz and 2450 MHz frequencies in accordance with IEEE 1528 and IEC 62209 international standards and to investigate the temperature effect during SAR measurements. Accreditation studies will be carried out for SAR measurements by preparing quality documentation.

Gas mixture analysis, preparation of gas mixtures in desired ratios and impurity analysis of gases supplied from suppliers can be performed upon request.
In addition, measurements within the scope of the European project EMRP IND12 will also be made with this system.
Solid materials (crystals, semiconductors, superconductors, etc.) have made great contributions to the world of science. Systems such as sensors and devices that are created using these materials are used in many different fields for technological purposes. The mechanical, optical and thermal properties of solid materials are the main subjects of research. The speed of sound in a material, which is one of the mechanical properties, is related to the elastic constant of the material and is a property that defines the solid material. In this sense, the speed of sound or elastic constants must be determined with high accuracy. The determination of changes in the speed of sound and indirectly in the elastic constants with respect to external factors such as temperature, pressure, magnetic field, etc. acting on the material allows us to obtain information about the structure within the material, so the detection of changes in the speed of sound with respect to other variables is another important issue. In this project, the Pulse Echo Overlap (PEO) method is used to determine the absolute speed of sound and changes in the speed of sound within the material with high accuracy. When the project is completed, a measurement system capable of making absolute sound velocity measurements with 5/10000 accuracy will be established. In addition to this, with the same measurement system, an automatic system that can measure the speed of sound at desired temperatures starting from low temperatures up to room temperature will be formed. Thus, a new quantity will be added to the existing quantities that can be measured in the Acoustics Laboratory under the title of measuring the absolute speed of sound in solid materials. Thanks to the knowledge, experience and experience gained as a result of the project, the infrastructure will be prepared for the demands of the industry in this direction.

Thus, the traceability of reference thermocouples in the temperature range of 1084 °C to 1325 °C will be ensured with high accuracy.
With this project, it is aimed to expand the AC current measurement capability of TÜBİTAK UME from 20 A to 100 A (10 Hz - 100 kHz) to meet the traceability needs within the country. Within the scope of the project, the design, construction and characterization of three AC-DC current shunts with current values of 30 A, 50 A and 100 A will be carried out.
It is possible to connect the devices used in nanotechnology to the metrological traceability chain as the transfer standard of the meter length standard in nanometer scale by using the reflection and diffraction of light from optical gratings, which we can call periodically structured surfaces proportional to its wavelength. In this way, the accuracy and measurement unity of devices that are now frequently used in nanotechnology such as scanning probe microscopes, optical microscopes, scaterometer systems can be ensured.
The laser diffractometer system, which uses the principle of optical diffraction, ensures that the optical gratings used for this purpose are calibrated and therefore included in metrological traceability.

Highly stable laser wavelength standards are needed for length and displacement measurements. In dimensional metrology, dimension measurements are performed by laser interferometry. The wavelength stability and accuracy of the laser used in laser interferometry measurements determine the accuracy and uncertainty of the measurement. In the project, Zeeman Stabilized lasers operating at 633 and 543nm wavelengths will be developed. The developed laser measurement systems will be developed into devices with commercial features. The 633 and 543nm wavelength stable laser measurement systems to be realized as a result of the project will be used as a wavelength stable radiation source in the short gauge block interferometer developed for commercial purposes in the Time Frequency and Wavelength Standards Laboratory of TÜBİTAK National Metrology Institute.
Certified reference materials are the most important tools for the reliability of chemical measurement results. They are widely needed for quality control purposes, especially in samples where the matrix effect is intense. Hazelnut is an agricultural product that has great importance considering the export volume of our country, but it is an agricultural product that does not have certified reference material needed during its analysis. This project aims to overcome the lack of matrix certified reference material for hazelnuts, which we have a say in the world.
The properties of water intended for human consumption, which is of great importance for human health, are given in the "Regulation on Water Intended for Human Consumption" and "TS266/2005 Standard" and the highest values are specified for toxic elements that threaten our health.

Certified reference materials, which provide primary level metrological traceability in national marker measurements, are used in authorized reference laboratories.
Chloramphenicol is an antibiotic that continues to be widely used in veterinary medicine. However, due to the harmful effects of its metabolites (by-products formed during excretion from the body), the permissible amount of chloramphenicol in animal foods (meat / milk / honey) is protected by law. Chloramphenicol residue analysis in animal foods is frequently performed in our country and in the world. TÜBİTAK UME has completed the production of "Chloramphenicol Primary Calibrant-UMECRM1301" and certified it as of 22.03.2013.
