|A system for issuing, registering and using OIML Certificates of Conformity|
The OIML Certificate System for Measuring Instruments was introduced in 1991 to facilitate administrative procedures and lower the costs associated with the international trade of measuring instruments subject to legal requirements.
In 2003 the OIML introduced the OIML Mutual Acceptance Arrangement (“OIML MAA”) as a tool to increase the level of mutual confidence provided by the OIML Basic Certificate System. The OIML MAA was implemented in January 2005, and its purpose is to establish a worldwide multilateral arrangement which offers a wider scope than bilateral or regional arrangements.
Today the OIML Certificate System remains a voluntary system for issuing, registering and using OIML Certificates of Conformity and associated OIML Type Evaluation Reports for types of measuring instruments based on the requirements of OIML Recommendations. It comprises two schemes: one for Basic Certificates and one for MAA Certificates.
Benefits of the OIML Certificate System
The OIML Certificate System aims to facilitate, accelerate, and harmonize the work of national and regional bodies that approve types of measuring instruments subject to legal control.
The various stakeholders may benefit from the OIML Certificate System:
Who issues OIML Certificates?
OIML Basic Certificates are issued by Issuing Authorities appointed by OIML Member States after completing all the tests, evaluations and examinations specified in the relevant OIML Recommendation and after it is demonstrated that the type complies with the requirements of the Recommendation.
Issuing Authorities that comply with the requirements of the MAA (called Issuing Participants), may issue MAA Certificates.
Registration of Certificates
The Issuing Authorities send a copy of the Certificates to the BIML for registration, for which the BIML invoices a registration fee of 350 € for the budget period 2013-2016. Depending on each Issuing Authority’s policy, the Issuing Authority either pays this fee to the BIML, or the manufacturer pays the BIML directly. The list of registered Certificates is published on the OIML website.
Other information on the System, particularly concerning the rules and conditions for the application, issue, and use of OIML Certificates, may be found in OIML Publication B 3 OIML Certificate System for Measuring Instruments and in OIML Publication B 10 Framework for a Mutual Acceptance Arrangement on OIML Type Evaluations.
