Info for manufacturers

Existing OIML Certificate Systems

Manufacturers that wish to apply for an OIML Basic Certificate or an OIML MAA Certificate under the existing systems must select a suitable Issuing Authority or Issuing Participant respectively. Information on the Issuing Authorities can be found here and information on the Issuing Participants can be found here.

OIML-CS Certificates

However, from 1 January 2018 no new certificates under the Basic System and the MAA can be issued. Instead, manufacturers will need to apply to an OIML Issuing Authority under the OIML-CS for an OIML-CS Certificate and associated OIML type evaluation report.

Two types of OIML-CS Certificate will be available: Scheme A and Scheme B.

Under Scheme A, OIML Issuing Authorities will have to demonstrate their competence on the basis of accreditation or peer assessment. Utilizers and Associates signing the declaration commit themselves, in principle, to accept and utilize OIML type evaluation reports, when associated with an OIML Certificate (under Scheme A) issued by an OIML Issuing Authority, as the basis for issuing a national or regional type approval. If a Scheme A certificate is not accepted then the Utilizer or Associate must provide a written justification (N.B. this is not required if test results from a Manufacturer Test Laboratory (MTL) are used).

Under Scheme B, OIML Issuing Authorities can demonstrate their competence on the basis of a ‘self-declaration’. In this instance, Utilizers and Associates can choose to voluntarily accept and utilize OIML type evaluation reports, when associated with an OIML Certificate (under Scheme B) issued by an OIML Issuing Authority, as the basis for issuing a national or regional type approval. Any acceptance of Scheme B certificates may be detailed by the Utilizer/Associate in the declaration.

OIML Issuing Authorities, Utilizers and Associates

Information will be provided here on the organizations that have been approved to be an OIML Issuing Authority (including their scope), and on the Utilizers and Associates under the OIML-CS that will accept and utilize OIML type evaluation reports when associated with an OIML Certificate issued by an OIML Issuing Authority.
