The article discusses certified reference materials and proficiency testing. Reference materials are materials for which one or more property values are sufficiently homogeneous and well established to be used for the assessment of a measurement method or the calibration of an apparatus. A certified reference material is a reference material accompanied by a certificate for which one or more property values are certified by a procedure, which is based on corresponding results of several independent technically renowned methods. Proficiency testing serves for the determination of the laboratory performance and competence in the field of testing through interlaboratory comparisons. Interlaboratory comparison is the organization, performance, and evaluation of tests on identical samples through two or more laboratories.
