American Association for Laboratory Accreditation

Reference Material Producer

Accreditation Program

The A2LA Accreditation Program for Reference Material Producers is designed for producers of reference materials and certified reference materials who wish to demonstrate their competence by formal compliance with a set of internationally-recognized criteria. The program also provides users of reference materials, such as testing and calibration laboratories, with increased confidence that the reference materials being relied upon are being produced in accordance with specified technical and management system requirements and are of appropriate quality. A2LA now requires that its accredited testing and calibration laboratories procure and use reference materials from a reference material producer accredited to ISO Guide 34:2009 by an APLAC-recognized accreditation body, such as A2LA.

A2LA has been accrediting reference material producers for over a decade as demonstrated by our first accreditation, granted in November 2000.

Accreditation Requirements

Reference Material Producers are assessed against the general criteria contained within ISO Guide 34:2009 General Requirements for the Competence of Reference Material Producers. ISO Guide 34 cross-references, as normative documents, ISO Guide 30:2015 Selected terms and definitions, ISO Guide 31:2015 Contents of certificates, labels and accompanying documentation, and ISO Guide 35:2006 Reference Materials - General and Statistical Principles for Certification; thus conformance to these requirements is also mandatory for reference material producers seeking A2LA accreditation.

Advisory Committee

A2LA has developed a Reference Material Producer Advisory Committee (RMPAC) to assist the Association by providing technical input on policy creation and decisions related to the Reference Material Producer accreditation program. If you wish to participate on the RMPAC, we invite you to contact Ashly Carter, A2LA Program Manager, at acarter@A2LA.org.
