ILAC has published a brochure to promote the value of accreditation of Reference Material Producers (RMPs) to ensure the quality of Reference Materials. Accreditation is a means of determining the technical competence of RMPs to produce specific RMs. It provides formal recognition to competent RMPs, thus providing a ready means for RMs users to identify and select the most suitable RMs that meet their needs.
