This standard specifies the requirements for six types of steel wire braided reinforced hoses and hose assemblies with a nominal inner diameter of 5 to 51, among which R2ATS type has one more specification with a nominal inner diameter of 63. It is suitable for HFC, HFAE, HFAS and HFB water-based hydraulic fluids defined in GB/T 7631.2 within the temperature range of -40℃~+60℃, or suitable for GB/T 7631.2 within the temperature range of -40℃~+100℃ Specified HH, HL, HM, HR and HV oil-based hydraulic fluids. This standard does not include requirements for pipe joints, but is limited to requirements for the performance of hoses and hose assemblies.
