The OIML has drawn up systems to facilitate cooperation between its Members, notably concerning the recognition of Test Reports between them.
The OIML Certificate System for Measuring Instruments, established in 1991, allows designated bodies (OIML Issuing Authorities) to issue OIML Certificates of Conformity to attest the conformity of types of measuring instruments which are examined and tested according to the requirements of certain OIML Recommendations. For that purpose, those OIML Recommendations that are applicable within the System define detailed testing and examination procedures and report formats.
An additional tool to this System was implemented in 2005 to increase confidence in test and examination results. The OIML Mutual Acceptance Arrangement (MAA) allows a participant in a Declaration of Mutual Confidence (DoMC) to accept and utilize test and examination results issued by the other participants. This mutual confidence is based on an evaluation of the testing laboratories according to the requirements of ISO/IEC 17025 General requirements for the competence of testing and calibration laboratories.
Existing cooperation has increased thanks to the implementation of the OIML MAA. Under the MAA, the evaluation of the competence of the testing laboratories shall be demonstrated by one of the following means:
The 2006 MoU between ILAC and the OIML (signed on 12 November 2006) covers shared interpretations of common technical issues (e.g. assessments according to ISO/IEC 17025) and shared use of technical and metrological experts (validated by the OIML) and lead assessors (validated by National Accreditation Bodies, ILAC MRA signatories).
Extension to the IAF
Under the OIML MAA, the evaluation of the competence of OIML Issuing Authorities is only required in terms of a self-declaration. The requirements to be applied here are those of ISO/IEC Guide 65:1996 General requirements for bodies operating product certification systems.
To this end, the BIML has drawn up a Guide for the application of ISO/IEC Guide 65 to legal metrology (OIML D 29:2008). It should be noted that ISO/IEC Guide 65 has been superseded by ISO/IEC 17065:2012 Conformity assessment — Requirements for bodies certifying products, processes and services. The scope and structure have been fundamentally modified to be consistent with those of ISO/IEC 17021, the aim being to draw up a standard which can easily be used by accreditation bodies to assess certification bodies. OIML TC 3/SC 5 Conformity assessment now has a project (p5) to revise OIML D 29:2008.
Cooperation between the IAF and the OIML has been developed, similar to that between ILAC and the OIML and includes shared interpretation of appropriate ISO/IEC standards and development of OIML training for assessors of national accreditation bodies, signatories of the IAF Product MLA, who will be responsible for accrediting, in the field of legal metrology, product certification bodies, inspection bodies and bodies providing audit and certification of management systems.
The 2007 MoU, including its extension to include the IAF, was signed by Mr. Daniel Pierre (ILAC Chair), Mr. Thomas Facklam (IAF Chair) and Mr. Alan Johnston (CIML President) on 28 October 2007 during the ILAC/IAF General Assembly held in Sydney (see photo).

2010 Renewal of the MoU
The 2010 MoU replaces the one from 2007 and has been slightly revised. A note was added to clarify when “legal metrology” is considered to be included in the scope of accreditation.
The new MoU was signed on 28 October 2010 during the ILAC/IAF Joint General Assembly in Shanghai (see photo).

2014 Renewal of the MoU
On 16 October 2014 at the IAF-ILAC Joint General Assembly, held in Vancouver, Canada, a renewed MoU was signed by Mr. Peter Unger (ILAC Chair), Mr. Randy Dougherty (IAF Chair) and Mr. Peter Mason (CIML President). Compared to the 2010 version of the MoU, the amendments to the text are of an editorial nature. References to standards have been updated and the review period has been extended from three to five years.
