This European Standard specifies requirements for two types of wire braid reinforced compact hoses and hose assemblies of nominal bore from 6 to 25, types 1SC and 2SC. 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 °C to +100 °C; water based fluids at temperatures ranging from -40 °C to +70 °C; water at temperatures ranging from 0 °C to +70 °C. The standard does 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.
