Procedure for a State to become an Associate State of the CGPM

The CGPM has created the category of Associate State to provide those States not yet Member States of the BIPM with the means to establish links to the world's measurement system, and so facilitate recognition of the traceability of their measurements to the SI.


Overview of the procedure for a State wishing to become an Associate State of the CGPM:

  • After being motivated to participate in the activities of the BIPM contact should be made with the Director of International Liaison and Communication Department (Mr Andy Henson) or the BIPM Director (Dr M.J.T. Milton) who can provide detailed advice on the rights and obligations and the process to become an Associate.

  • Having decided to proceed, a State must make the formal national decision to become an Associate State of the CGPM in accordance with its own constitutional requirements.

  • The letter of application of a State wishing to become an Associate State of the CGPM must be sent to the BIPM Director by the Government of the state (usually the ministry in charge of the national metrology system/National Metrology Institute) through its ministry in charge of Foreign Affairs/Embassy in Paris**.

  • The payment of the first annual subscription (per calendar year) must be made directly to the BIPM.

The status of Associate State implies the intention to accede to the Metre Convention and become a Member State at an appropriate time in the future.

As the purpose of a State becoming an Associate is to be able to participate in the CIPM Mutual Recognition Arrangement (CIPM MRA), the above procedure is normally followed by the signature of the CIPM MRA by the Director of the National Metrology Institute of the new Associate. According to the CIPM MRA, signature also requires the prior approval of the same body that has the authority to approve the application to become an Associate.



* In exceptional circumstances it may be possible for an Economy to become an Associate of the CGPM, subject to special procedures under Resolution 3 (1999), Resolution 6 (2007) and Resolution 5 (2011).

** Not all States have an Embassy in Paris, and such States make arrangements to deal with the French Ministry for Europe and Foreign Affairs through, for example, their Embassy in Belgium.
