International Organization of Legal Metrology (OIML)

The International Organization of Legal Metrology (OIML) was set up by an intergovernmental convention signed in Paris in October 1955.

Its main purpose is to harmonize and coordinate the administrative and technical regulations governing measurements and measuring instruments in the various countries, drawing on the network of metrological services in its member states. The aims of this action are to facilitate free trade between countries in measuring instruments and in all products and services involving measurements, and to ensure a certain level of quality in measuring instruments manufactured throughout the world.

In this spirit, its member states have made a moral commitment to apply the instructions they have jointly drawn up on the construction, control and use of measuring instruments used in commerce, industry and laboratories, as well as those concerning health, environmental protection, etc.
