International Organization of Legal Metrology

The International Organization of Legal Metrology (French: Organisation Internationale de Métrologie Légale - OIML), is an intergovernmental organisation that was created in 1955 to promote the global harmonisation of the legal metrology procedures that underpin and facilitate international trade. Such harmonisation ensures that certification of measuring devices in one country is compatible with certification in another, thereby facilitating trade in the measuring devices and in products that rely on the measuring devices.
