Proficiency testing is an external method for assuring a laboratory’s accuracy in the performance of a specific test method. Participation in proficiency tests provides you with an objective and independent comparison of your quality and performance in the laboratory routine. The regular participation in proficiency tests is mandatory for testing laboratories with an accreditation according to ISO/IEC 17025.
Through regular participation in proficiency tests you will receive:
a performance evaluation in a specific test by comparison with reference values and to other participant laboratories.
the possibility to make test methods comparisons.
a proof of efficiency towards customers and certification bodies.
- Estimation of measurement uncertainty:
a plausibility proof of your measurement uncertainty estimation.
a cost saving through early detection of problems and corrective measures.
