Monitoring the work of the test laboratory by participating in the proficiency testing program in the field of the laser performance measurements

Monitoring the validity result is critical requirement of international standard ISO/IEC 17025:2017 for test and calibration laboratories to provide objective evidence their technical competence. Applying interlaboratory comparison, using alternative instrumentation that has been calibrated, functional checks measuring testing equipment, other methods monitoring results not enough have confidence in quality results. Modern standards field require applying forms assessing characteristics used method. Particularly, it concerns participation comparisons.
 One tools could be comparing laboratory with are obtained by laboratories, e.g. proficiency testing. This paper presents a program laser performance measurements was organized International provider IFM Quality Services PTY Ltd. 2021. The purpose demonstrate SE “Ukrmetrteststandard” performance, reveal correlation previous years different tasks assess possible causes outliers. Twenty-two had accredited 17025 participated were evaluated Z-score as criterion.
 Potential risks small number participants outliers assessed.
