Interlaboratory comparisons supporting accreditation

National and international mutual recognition arrangements, standards or quality systems set the requirements for the reliability of measurement results. Acquiring accreditation is the way for analytical laboratories to demonstrate their technical competence to their customers.

The international measurement evaluation programme (IMEP®) of IRMM enables assessing in how far laboratory accreditation is equivalent across the Member States. IRMM organises these interlaboratory comparisons in close collaboration with the European co-operation for Accreditation (EA) and the Directorates-General for Enterprise and for Taxation and Customs Union.

Contrary to most other external quality assessment schemes, participating laboratories in IMEP® can compare their measurement results with independent and traceable reference values obtained by measurements applying the principles of metrology. This also helps chemical laboratories to improve the quality of their measurements.
