Scope - QUASIMEME

WEPAL/QUASIMEME is accredited for the organisation of Inter laboratory Studies by the Dutch Accreditation Council RvA since April 26, 2000. WEPAL’s registration number is R002. The accreditation is based on the ISO/IEC-requirements (General requirements for proficiency testing, ISO/IEC 17043:2010). The scope of accreditation can be found on the website of RvA.

The accreditation covers the quality system of the organisation as well as the determinand groups printed in bold in the first column in the table below. Within these determinand groups only the determinands printed in bold in the second column meet the criteria for accreditation. These criteria are based on information about the homogeneity and stability of the samples. This information is available when sufficient participants have reported results for a determinand in the past 3 years. Determinands which are not reported regularly in sufficient numbers to have a statistical evaluation are not (yet) included in the scope of the accreditation.
