How do I participate in inter-laboratory comparisons?

ALGERAC as an associate member of EA and a full member of ILAC complies with harmonizing its policies and practices to maintain mutual recognition status.

One of the means that ALGERAC imposes on test/analysis and calibration laboratories, and if relevant, on inspection bodies, is to participate in inter-laboratory comparisons and proficiency tests, in order to demonstrate the validity and reliability of their results.

Consult GEN 05 (ALGERAC Policy on Inter-Laboratory Comparisons / Proficiency Testing).
