Defines requirements for ten classes, four grades and seven types of wireor textile-reinforced hydraulic hoses and hose assemblies of nominal sizes ranging from 5 to 102.

This International Standard specifies requirements for ten classes, four grades and seven types of wire- or textile-reinforced hydraulic hoses and hose assemblies of nominal sizes ranging from 5 to 102. Each class has a single maximum working pressure for all sizes. Such hoses are suitable for use with hydraulic fluids HH, HL, HM, HR and HV as defined in ISO6743‑4 at temperatures ranging from –40°C to +100°C for typesAS, AC, BS and BC and –40°C to +120°C for typesCS, CC and DC. This International Standard does not include requirements for the connection ends. It is limited to the performance of hoses and hose assemblies. The hose assembly maximum working pressure is governed by the lowest maximum working pressure of the components. NOTE It is the responsibility of the user, in consultation with the hose manufacturer, to establish the compatibility of the hose with the fluid to be used.
