Measurement Audits


PTTn Measurement Audits are conducted by comparing laboratory results to values established by a reference laboratory, taking into account the measurement uncertainties assigned to the reference value and those reported by each participating laboratory. Performance is evaluated by the internationally accepted method of calculating En ratios.

Measurement Audits may be organised by PTTn upon request. Note that participation in a Measurement Audit would satisfy ISO 17025 General Requirements for Competence of Testing and Calibration Laboratories, clause 5.9.
