This European Standard specifies requirements for two typres of wire braid reinforced compact hoses and hose assemblies of nominal bore form 6 to 25.
They are suitable for use with:
- hydraulic fluids in accordance with ISO 6743-4 with the exception of HFD R, HFD S and HFD T at temperatures ranging from -40℃ to +100℃；
- water based fluids at temperatures ranging from -40℃ to +70 ℃;
The standard dose not include requirements for end fittings. It is limited to the performance of hoses and hose assemblies.
Note 1: The hoses are not suitable for use with castor oil based nor ester based fluids.
Note 2: Hoses and hose assemblies should not be operated outside the limits of this standard.
Note 3: Requirements for hydraulic hoses for underground mining are standardised in separate standards.
Types of hoses
Two types of hoses are specified:
-Type 1SC- hoses with a single braid of wire reinforcement;
-Type 2SC- hoses with two braid of wire reinforcement.
Material and construction
Hoses shall consist of an oil and water resistant synthetic rubber lining, one or two layers of high tensile steel wire and an oil and weather resistant synthetic rubber cover.
Hose assemblies shall only be manufactured with those hose fittings whose functionality has been verified in all tests according to this standard.
Impulse test requirements
A.The impulse test shall be in accordance with ISO 6803. The test temperature shall be 100℃.
B.For type 1SC hose, when tested at impulse pressure equal to 125% of the maximum working pressure, the hose shall withstand a minimum of 150,000 impulse cycles.
C.For type 2SC, when tested at impulse pressure equal to 133% of the maximum working pressure, the hose shall withstand a minimum of 200,000 impulse cycles.
There shall be no leakage or other malfunction before reaching the specified number of cycles.
This test shall be considered a destructive test and test piece shall be thrown away.
