The purpose of this standard is to ensure interchangeability of vehicles and implements. The minimum requirements on the performance and the components of the hydraulic system as well as the kind, the size and the location of the connecting elements between the vehicle and the implement are specified in this standard. This standard does not deal with airport equipment. This standard does not cover applications, where the implements need a continuous hydraulic oil flow exceeding 45 l/min.
