governmental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated
to the member bodies for approval before their acceptance as International
Standards by the IS0 Council.

AVANr-PROPOS
L'ISO (Organisation internationale de normalisation) est une fédération mondiale
d'orga n ~ ismes nationaux de normalisation (comités membresde I'ISO). L'élaboration
des Normes internationales est confiée aux comités techniques de I'ISO. Chaque
comité membre intéressé par une étude a le droit de faire partie du comité technique
correspondant. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec I'ISO, participent également aux travaux.
Les projets de Normes internationales adoptés par les comités techniques sont
soumi ' aux comités membres pour approbation, avant leur acceptation comme
7.
Normes internationales par le Conseil de I'ISO.
La Ndrme internationale IS04399 a été élaborée par le comité technique
lSO/TC 131, Transmissions hydrauliques et pneumatiques, et a été soumise aux
comités membres en janvier 1976.
