An OIML Issuing Authority is a certification body in an OIML Member State that has been approved to issue OIML certificates and OIML type evaluation reports

An organization that wishes to become an OIML Issuing Authority needs to demonstrate compliance with the requirements of ISO/IEC 17065 (and OIML D 32).

To be an OIML Issuing Authority for measuring instrument categories that are in Scheme A, the organization needs to demonstrate compliance through accreditation or peer assessment. For measuring instrument categories that are in Scheme B, a ‘self-declaration’ (with supporting evidence) is sufficient for demonstrating compliance.

An application form to become an OIML Issuing Authority is available to download here.

A summary of OIML Issuing Authorities and their scopes can be found here.

Note: A six-year transition period from 1 January 2018 is provided whereby a self-declaration, with supporting evidence, can be used to demonstrate compliance with ISO/IEC 17065 under Scheme A.

Test Laboratories

Ruler

OIML Issuing Authorities need to designate a Test Laboratory(ies) that will be responsible for performing certain or all tests on a type of measuring instrument. The scope of the Test Laboratory(ies) must cover the intended scope of the OIML Issuing Authority.

Test Laboratories need to demonstrate compliance with the requirements of ISO/IEC 17025 (and OIML D 30), with compliance demonstrated through accreditation or peer assessment under Scheme A and ‘self-declaration’ under Scheme B.

A Test Laboratory can be an internal Test Laboratory of the OIML Issuing Authority, a third-party Test Laboratory, or a Manufacturer Test Laboratory (MTL).

An application form to include a Test Laboratory is available to download from here.

Declaration

Ruler

Once approved, the OIML Issuing Authority signs a Declaration stating that it will abide by the rules of the OIML-CS. The scope of the OIML Issuing Authority and its associated Test Laboratory(ies) will be detailed in the Declaration.

Utilizer status

Ruler

Where an organization becomes an OIML Issuing Authority under Scheme A, the OIML Member State must designate at least one Utilizer for that category of measuring instrument. The Utilizer(s) may be a different organization(s) than the OIML Issuing Authority. The requirement to designate at least one Utilizer shall not apply when the OIML Member State does not regulate that particular category of measuring instrument in their country. Information on becoming a Utilizer under the OIML-CS can be found here.

Requirements for peer and accreditation assessments

Ruler

For peer assessments of OIML Issuing Authorities and Test Laboratories, an approved Management System Expert (team leader) and Legal Metrology expert(s) from the OIML-ILAC-IAF list of approved experts must be used.
