OIML

The Organisation Internationale de Métrologie Légale (OIML) is a world wide, intergovernmental organization whose main task is that of harmonizing the metrological regulations and controls applied by the national metrological services, or related organizations, of its Member States.

The two main categories of OIML publications are :

International Documents (OIML D), of an informative nature, to help and improve the work of the metrological services.

International Recommendations (OIML R), which are model regulations generally establishing the metrological characteristics required of the measuring instruments concerned and specifying methods and equipment for checking their conformity; the OIML Member States shall implement these Recommendations as far as possible,

On prepackaging two recommendations exist:
- OIML R79, Labeling requirements for prepackaged products (1997)
- OIML R87, quantity of product in prepackages (2004)

These recommendations can be downloaded for free at the OIML website.
