Proficiency Testing and other Comparisons for Laboratories

Interlaboratory comparison (ILC) and proficiency testing (PT) represent significant elements in the integrated evaluation of the technical competence of laboratories.
SNAS considers the participation of laboratories in ILC and PT projects as an important means of verification of the fulfilment of accreditation criteria of accredited laboratories.

In connection with ILC and PT SNAS has issued several documents, such as PL-23 and MSA-L/08 to check activities in this field.

SNAS requires laboratories to take an active part in ILC and PT projects organised in Slovakia or on an international level by EA, or by other accreditation systems in compliance with the applicable EA regulations.

In cases where proficiency testing is impractical, SNAS has accepted rules for ensuring the acceptable level of measurement traceability as declared in MSA-L/08.
