GB/T 39313-2020 Rubber hoses and hose assemblies—Compact wire-braid-reinforced hydraulic types for oil-based or water-based fluids—Specification

Scope: This standard specifies the requirements for five types of dense steel wire braided reinforced hose and hose assemblies, with a nominal inner diameter ranging from 5 to 31.5. These hoses are suitable for --- oil-based hydraulic fluids HH, HL, HM, HR and HV defined in ISO6743 4, with a temperature range of -40 °C ~ +100 °C; --- water-based hydraulic fluids defined in ISO6743 4 HFC, For HFAE, HFAS and HFB, the temperature range is 0°C~+60°C; ---water, the temperature range is 0°C~+60°C. This standard does not include requirements for hose joints, but is limited to requirements for hoses and hose assemblies. Note: It is the user's responsibility to consult the hose manufacturer to determine the compatibility of the hose with the fluid being used.
