Proficiency testing - how much and how often?


Factors affecting PT strategyAn accredited laboratory needs to define in which PT schemes it should enrol  and how often it should participate. The EURACHEM Proficiency Testing Working Group has produced an information leaflet to help laboratories select the right balance of areas of work and participation frequency. The leaflet is currently available in English; further translations are in hand and will be published when available.



Please consult the PT Working Group Chair if you would like to prepare a translation in your own language.
