Dear Calibration Laboratory Authorities,

Inter-Laboratory Comparisons (ILC) and Proficiency Tests (PT) are important tools to assess the technical competence of calibration and/or testing laboratories. This is also specifically stated in the TS EN ISO/IEC 17025 standard and the TÜRKAK document. It is a requirement of the TS EN ISO/IEC 17025 standard and TURKAK that accredited laboratories or laboratories applying for accreditation participate in LAKs related to the measurement quantities within their scope of accreditation and have achieved successful results.

It is planned to organize a LAK taking into account the need for time interval measurement comparison of calibration laboratories that are accredited and/or planning to be accredited in the country.

This comparison includes measurements of the delay of three cables (average: 30 ns, 90 ns and 140 ns).
 
Regarding your participation www.ume.tubitak.gov.tr After filling out our "Interlaboratory Comparison / Competence Application Form", which you can access from the "Our Services" heading at 15/09/2022 ume@tubitak.gov.tr We kindly ask you to send it to the address.

NOTE: The technical protocol and measurement dates of the comparison will be determined and sent to the applicants after the number of participants is determined.
