Resumen:
This European Standard specifies requirements for two types of wire braid reinforced compact hoses and hose assemblies of nominal bore from 6 to 25, types 1SC and 2SC. 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 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.
