OIML logo

The OIML (International Organization of Legal Metrology) is one inter-government organisation created in 1955 with the aim of coordinating and harmonizing at international level the administrative and technical regulations applying to measurements and measuring instruments passed by the different countries. The OIML comprises 59 Member States and some 54 corresponding members. The OIML has been recognized as an international standardization organization by the World Trade Organization (WTO).

The purpose of this harmonization is to facilitate trade between countries not only for the measuring instruments but also for all the operations involving measurements. To achieve that, the OIML is developing international recommendations.

The OIML is operating through a permanent Secretariat based in Paris and called International Bureau of Legal Metrology (BIML). This Bureau centralises works carried out by the technical secretariats located in the Member countries and also coordinates all OIML activities.

The official languages of the OIML are French and English.

The BIML publishes a specialist review: "Le Bulletin de l'Organisation Internationale de Métrologie Légale".
