摘要：

The programmes of the European Commission for the certification of reference materials are presented: the Standards, Measurement and Testing Programme (formerly ''BCR Programme'') funds research and development aiming at improved ability to measure and at improved comparability of measurements; reference materials result from many of its projects; the Institute for Reference Materials and Measurements (formerly ''CBNM'') prepares some of these, stores nearly all of them, will distribute them from 1995 on and certifies some additional ones. The principles adopted for the certification of ''BCR'' reference materials are explained. The procedure for a typical matrix reference material is that a group of laboratories first refines their methods (e.g. by intercomparisons and technical discussion) until they achieve agreement of results to within random experimental error and then analyses the reference material; certified value and uncertainty are calculated on the basis of their results. Recent achievements and projects in progress are listed.
