APLAC is a regional cooperation among accreditation bodies in the Asia Pacific region.  Initially these accreditation bodies accredited testing and calibration laboratories.  Increasingly, however, they now also accredit inspection bodies, reference material producers, and other related services.

Part of APLAC’s role is to provide a forum for the exchange of information among its members on accreditation and related issues, with the aim of continual improvement of accreditation services offered in the region.  Through the APLAC Mutual Recognition Arrangement (MRA) APLAC facilitates the acceptance by governments and industry in each economy of reports and certificates from facilities accredited by signatories to the MRA.  APLAC is an ILAC-recognised region and most signatories to the APLAC MRA are also Members of ILAC (signatories to the global ILAC Arrangement).

APLAC undertakes various activities to support its member accreditation bodies, including

As a Specialist Regional Body (SRB) recognised by the Asia Pacific Economic Cooperation (APEC) Sub-Committee on Standards and Conformance (SCSC), APLAC supports the trade facilitation and related activities of APEC.
