This standard specifies the requirements for 5 types of wire-wound reinforced hydraulic hoses and hose assemblies with inner diameters ranging from 6.3mm to 51mm. They are suitable for HH, HL, HM, HR and HV hydraulic fluids that meet the requirements of GB/T 7631.2. The applicable temperature range of 4SP and 4SH types is -40°C to +100°C, and the applicable temperature range of R12, R13 and R15 types is -40°C to + 120°C. This standard does not apply to castor oil-based or fat-based fluids. This standard does not include requirements for fittings, but is limited to performance requirements for hoses and hose assemblies.
