Abstract
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.
