Agricultural tractors and machinery — Coding of remote hydraulic power services and controls
This document specifies the coding to be used to identify the couplings and controls for the remote hydraulic power services of agricultural tractors, machinery, and implements.
Tracteurs et matériels agricoles — Codage des commandes et services hydrauliques à distance
La présente Norme internationale prescrit les codes à utiliser pour identifier les couplages et les commandes destinés aux services hydrauliques à distance des tracteurs, machines ou instruments agricoles. L'identification des couplages et des commandes sera utile aux fabricants d'instruments agricoles pour leur permettre d'identifier les tuyaux souples des intruments par le symbole du vérin rentré ou sorti approprié. Cela les aidera à assurer un fonctionnement correct de l'instrument lorsque celui-ci est relié au tracteur.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
