BSI | 2019 | 20 |
This European Standard specifies requirements for four types of rubber-covered spiral wire reinforced hydraulic hoses and hose assemblies of nominal bore from 6 to 51: Types 4SP, 4SH, R12 and R13. They are all 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 for types 4SP and 4SH and ?40 °C to +120 °C for types R12 and R13; – water based fluids at temperatures ranging from ?40 °C to 70 °C; – water fluids at temperatures ranging from 0 °C to 70 °C. This European 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 are not be operated outside the limits of this standard. NOTE 3 Requirements for hydraulic hoses for underground mining are standardised in a separate standard.
