Summary: This standard specifies the requirements for steel or fabric reinforced hydraulic rubber hoses and hose assemblies of 10 types, 4 grades and 7 types with a nominal inner diameter of 5 to 102. All specifications and each type have a single maximum working pressure. Among them, AS, AC, BS and BC type hoses are suitable for ISO 6743-4 requirements, and the temperature is -40�桫+100�� HH, HL, HM, HR and HV oil-based hydraulic fluid; CS, CC, and DC hoses are suitable for HH, HL, HM, HR and HV oil-based hydraulic fluids with a temperature of -40�桫+120��. This standard does not include requirements for joints, but only for hoses and their assemblies. The maximum working pressure of the hose assembly is determined by the lowest value of the maximum working pressure of each component.

1 Scope

This standard specifies 10 types, 4 grades and 7 types of steel wire or fabric reinforced hydraulic rubber with a nominal inner diameter of 5 to 102 Requirements for hoses and hose assemblies. All specifications and each type have a single maximum working pressure, of which AS, AC, BS and BC type hoses are suitable Used for HH, HL, HM, HR and HV oil-based hydraulic fluids that meet the requirements of ISO 6743-4 and the temperature is -40℃~100℃; CS, CC, and DC hoses are suitable for HH, HL, HM, HR and HV oil-based hydraulic fluids with a temperature of -40°C to 120°C. This standard does not include requirements for joints, and is limited to requirements for hoses and their assemblies. The maximum working pressure of the hose assembly is determined by each component The minimum value of the maximum working pressure is determined. Note. The user is responsible for consulting the hose manufacturer to determine the compatibility of the hose with the fluid used.
