Abstract
Certified reference materials are widely used for the calibration of measuring equipment and for the evaluation or validation of measurement procedures. The use of reference materials makes possible the transfer of the values of measured or assigned quantities between testing, analytical and measurement laboratories, both nationally and internationally. There is an increasing number of reference materials producers in other countries, and a demonstration of their scientific and technical competence is now more widely considered to be a basic requirement for ensuring the quality of reference materials. This article outlines recent activities by international bodies and their culmination in a scheme of accreditation of certifiers of reference materials which has been developed by the National Association of Testing Authorities, Australia (NATA).
