25、semblies of nominal bore from 5 to 51. 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 rangi

26、ng 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 and ester based fluids. NOTE 2 Hoses and hose assemblies are not be operated out
