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.
