International Scenario of Legal Metrology
The International Organization of Legal Metrology (OIML)
The International Organization of Legal Metrology is an intergovernmental treaty organization which:
- Develops model regulations, standards and related documents for use by legal metrology authorities and industries.
- It provides mutual recognition systems that reduce trade barriers and costs in a global market.
- Represents the interests of the Legal Metrology community within international organizations and forums concerned with metrology, standardization, testing, certification, and accreditation.
- Promotes and facilitates the exchange of knowledge and competencies within the legal metrology community worldwide.
- Cooperates with other metrology bodies to raise awareness of the contribution that a sound legal metrology infrastructure can make to a modern economy.
“The mission of the OIML is to enable economies to put in place effective legal metrology infrastructures that are mutually compatible and internationally recognized, for all areas for which governments take responsibility, such as those which facilitate trade, establish mutual confidence and harmonize the level of consumer protection worldwide.” – OIML B 15:2011
The OIML issues several categories of publications:
- International Recommendations, which are intended as model regulations for a number of categories of measuring instruments, and which OIML Member States are morally obliged to implement as far as possible.
- International documents, which are informative and are intended for guidance purposes; and
- Other publications such as Vocabularies, Guides, Basic Publications, and Expert Reports.
In addition, the OIML has developed the following international systems:
- The OIML Basic Certificate System for Type Evaluation of Measuring Instruments, in which participants use harmonized methods to assess and certify the conformity of types of measuring instruments with the requirements of OIML recommendations, on a voluntary basis.
- The Framework for a Mutual Acceptance Arrangement on OIML Type Evaluations (MAA), in which participants declare that they intend to accept and utilize type evaluation reports from those participants that are entitled to issue OIML MAA Certificates.
