Proficiency testing

Proficiency tests prove the competence of calibration service providers

Instrument calibration is a standard element of ISO 9001 quality systems for industrial manufacturing plants. But performing calibrations at a regular frequency does not guarantee accurate measurements unless the calibration process is externally verified. Poor calibrations lead to inaccurate meters, which have consequences for product quality, energy efficiency, yield, and financial losses.

Proficiency tests are the globally recognized best practice for testing the competence of calibration service providers. They are a primary requirement for accreditation according to ISO 17025. Endress+Hauser runs a proficiency test program across all our calibration service centers worldwide. It examines the competence of our service centers and identifies shortcomings for corrective action. The result is a high level of confidence in calibrations.
