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 1The hoses are not suitable for use with castor oil based nor ester based fluids.NOTE 2Hoses and hose assemblies are not be operated outside the limits of this standard.NOTE 3Requirements for hydraulic hoses for underground mining are standardised in a separate standard.
