Proficiency Testing (PT) & Measurement Audit (MA)
Proficiency Testing (PT)
Proficiency Testing (PT) is an evaluation of participant performance against pre-established criteria by means of interlaboratory comparisons according to ISO/IEC 17043:2010. Interlaboratory Comparisons involves organization, performance and evaluation of measurements or tests on the same or similar items by two or more laboratories in accordance with predetermined conditions.
Measurement Audit (MA)
Measurement audit involves a well characterised and calibrated artefact usually sent to only one laboratory where their results are compared to a reference value which is normally supplied by a national metrology institute.
Proficiency Testing and Measurement Audit is organised by NMIM. Note that participation in a Proficiency Testing and Measurement Audit would satisfy ISO 17025 General Requirements for Competence of Testing and Calibration Laboratories, clause 5.9.
