General information

The Asia Pacific Metrology Programme (APMP) is a grouping of national metrology institutes (NMIs) from the Asia-Pacific region engaged in improving regional metrological capability through the sharing of expertise and exchange of technical services among Member laboratories. APMP is also a Regional Metrology Organization (RMO) recognized by the International Committee for Weights and Measures (CIPM) for the purpose of worldwide mutual recognition of measurement standards and of calibration and measurement certificates.


APMP's mission is to promote and support a measurement infrastructure in the Asia-Pacific region that facilitates international trade, improves industrial efficiency and competitiveness, ensures equity in the marketplace, and enhances the quality of life and the environment.


APMP's vision is to become an inclusive, representative and transparent regional metrology organization providing leadership for meeting the measurement challenges of the region.


APMP has been operating in the Asia-Pacific since its inception as a Commonwealth Science Council initiative in 1977. Eligible membership was broadened outside the Commonwealth in 1980 when the present title (APMP) was established. As such, it is the oldest continually operating metrological grouping in the world.

APMP grew out of a need by participating members to develop their metrological capability. It was based on a true collaborative spirit of mutual assistance and sharing of expertise and information, and this remains one of the major strengths of APMP to this day.

In early years, the emphasis of APMP was on training and calibration assistance aimed at raising the level of metrology and expertise in primary standards laboratories within the region. This was achieved on a collaborative basis, usually working bilaterally between members. More recently, as rapid technological development and industrial growth have placed increased demands on metrological services, and there is growing recognition of the importance of metrology to international trade through conformance testing and quality systems, the emphasis in APMP has shifted towards gaining international recognition and credibility for its members.


APMP operates under the framework of APMP Memorandum of Understanding (MoU). The first version of MoU came into effect on 30 Sep 1997, finalized following discussions at the 12th APMP Committee Meeting in Philippines in Oct 1996. The latest version of MoU was revised and adopted by the 35th General Assembly in Sydney, Australia in December 2009.


At the 14th Committee Meeting held in Malaysia in Sep 1998, APMP was re-arranged with the Committee Meeting re-named as General Assembly, an Executive Committee established to support Chairperson, and Technical Committees established for each quantity.

At present, under the framework of MoU, APMP operates under the supervision of the Executive Committee, the managing body, headed by a Chairperson and assisted by a Secretariat as the coordinating body. APMP has 12 Technical committees (TCs) responsible for coordinating technical activities for each field covered by the CIPM's Consultative Committees, and 1 Developing Economies' Committee (DEC) responsible for initiating and coordinating work programs to address the needs of APMP member Developing Economy NMIs (DENs). APMP also established 5 Focus Groups (for Clean Water, Climate Change and Clean Air, Energy Efficiency, Food Safety, and Medical Metrology) to promote liaison with and provide measurement support to stakeholders in identified priority fields.


APMP has 45 full members (27 economies) and 14 associate members (13 economies). There are:

- 21 Member States of the BIPM and 9 Associates of the CGPM

- 30 Signatories of the CIPM MRA
