GB/T 10544-2022Rubber hoses and hose assemblies - Rubber-covered spiral-wire-reinforced hydraulic types for oil-based or water-based fluids - Specification (English PDF)

foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1.Structure and Drafting Rules of Standardization Documents"

drafted.

This document replaces GB/T 10544-2013 "Rubber hoses and hose assemblies for oil-based or water-based fluids with wire wound reinforcement

Compared with GB/T 10544-2013, except for structural adjustment and editorial changes, the main technical changes

as follows.

--- The upper limit temperature of water-based fluids in the range is expanded from 60°C to 70°C (see Chapter 1, Chapter 1 of the.2013 edition);

--- For R15 type, a specification with a nominal inner diameter of 51 is added (see Table 1);

---In the pulse performance test, the "optional pulse test" has been incorporated into the "water-based fluid resistance test" as an option. The temperature of the water-based fluid

Raised from 60°C to 70°C (see 7.4, 7.4 of the.2013 edition);

--- Increased wear resistance test requirements (see 7.8);

--- The immersion temperature of the water resistance test is increased to 70 °C, and the volume change rate of the inner lining and outer covering of the hose is respectively required (see

7.9.3, 7.8.3 of the.2013 edition);

--- Increased the test frequency requirements (see Chapter 8).

This document is equivalent to ISO 3862.2020 "Rubber hoses and hose assemblies suitable for oil-based or water-based fluids, wire wound reinforcement

Specification for Rubber Covered Hydraulic Types.

1 Scope

This document specifies five types of wire wound reinforced hydraulic hoses and hose assemblies with a nominal inner diameter of 6.3mm~51mm.

Require.

This document applies to hoses and hose assemblies using the following media.

---HH, HL, HM, HR and HV oil-based hydraulic fluids defined by ISO 6743-4, of which 4SP and 4SH types are applicable to the temperature range

The temperature range is -40 degrees C~100 degrees C, and the applicable temperature range of R12, R13 and R15 type is -40 degrees C~120 degrees C;

---HFC, HFAE, HFAS and HFB type water-based hydraulics with a temperature range of -40°C to 70°C as defined by ISO 6743-4

fluid;

--- Water with a temperature range of 0°C to 70°C.

This document does not cover requirements for joints. Only for hose and assembly requirements.

NOTE. It is the user's responsibility to consult the hose manufacturer to confirm the compatibility of the hose with the fluid being used.
