They are suitable for use with: hydraulic fluids in accordance with ISO 6743-4 with the exception of HRD R, HFD S and HFD at temperatures ranging from -40 C to 100 C; water-based fluids at temperatures ranging from -40 C to +70 C; water at temperature ranging from 0 C to +70 C. The European S

27、tandard 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 outside the limits of this standard. NOT
