Reference Materials Producers Accreditation Program

To view the listing of accredited Reference Materials Producers, please click here.

The A2LA Accreditation Program for Reference Material Producers is designed for producers of certified reference materials and reference materials who wish to demonstrate their competence by formal compliance with a set of internationally recognized criteria. The program will also provide users of reference material, 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.

In December 2007, A2LA expanded its Asia Pacific Laboratory Accreditation Cooperation Mutual Recognition Arrangement (APLAC MRA) Scope to include the Reference Material Producer Accreditation Program. This arrangement calls for the signatory Accreditation Bodies to operate to ISO/IEC 17011 and assess reference material producers to ISO Guide 34 in combination with ISO/IEC 17025.

The requirements for this program are listed in C307 - General Checklist: ISO Guide 34-2009 Reference Material Producer Accreditation Program and are based on those contained in ISO Guide 34:2009, "General requirements for the competence of reference material producers" ISO Guide 34 sets out the general requirements in accordance with which a reference material producer has to demonstrate that it operates, if it is to be recognized as competent to carry out the production of reference material. It is recognized that each reference material needs to be characterized mainly to the level of accuracy required for its intended purpose (i.e. appropriate measurement uncertainty.)

ISO Guide 34 cross references, as normative documents, ISO Guide 30:1992, "Terms and Definitions Used in Connection with Reference Materials", ISO Guide 31:2000, "Reference Materials - Contents of Certificates and Labels", and ISO Guide 35:2006 "Reference Materials - General and Statistical Principles for Certification); thus conformance to these requirements is also mandatory for the accreditation of reference material producers.

An Interim Application to the Standard

This section presents A2LA's official applications of the ISO Guide 34:2009 requirements. It is expected that reference material producers will implement the requirements of the standard in accordance with the applications listed here. Otherwise, areas of non-conformance will be identified by the assessor during the on-site assessment.
