The use of reference materials and the participation in proficiency testing are required for all accredited laboratories per the international standard DIN EN ISO/IEC 17025 "General requirements for the competence of testing and calibration laboratories". 

But quality assurance is also a "must" for company laboratories that are not accredited. Only in this way can analytical accuracy be ensured and documented, and the slightest deviations identified at an early stage.

As an accredited proficiency testing provider, muva kempten GmbH has been conducting international proficiency tests competently and reliably for almost 30 years. We have been offering high-quality reference material for the internal control of laboratories for just as long. Of course, all such materials obtainable from us are tested prior for homogeneity and stability.
