Interlaboratory comparisons

IRMM operates an International Measurement Evaluation Programme (IMEP), a Regular European Interlaboratory Measurement Evaluation Programme (REIMEP) for nuclear measurements, an Interlaboratory Measurement Evaluation Programme for Nuclear Signatures in the environment (NUSIMEP), and organises proficiency tests and validation studies.

Many of the interlaboratory comparisons are open to all laboratories that wish to participate but some are restricted to e.g. national reference laboratories or in the case of nuclear measurements to those that are licenced to keep/import radioactive samples. Proficiency test are normally carried out only on request of another Commission department or agency. Some comparisons are run to certify reference materials and validation studies are organised regularly to validate analysis methods.

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.

Various aspects of the interlaboratory comparison can from time to time be subcontracted.  When subcontracting occurs, it is placed with a competent subcontractor and the interlaboratory comparison provider is responsible for this work.
