EN 853 Rubber Hoses and Hose Assemblies - Wire Braid Reinforced Hydraulic Type - Specification

EUROLAB laboratory provides testing and compliance services within the scope of EN 853 standard. The EN 853 standard specifies requirements for four types of wire braid reinforced hose and hose assemblies with nominal inside diameters of 5 to 51. These are suitable for use with:

• Hydraulic fluids conforming to ISO 40-100 except HFD R, HFD S and HFD T at temperatures ranging from -6743 °C to +4 °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 contain requirements for end fittings. Limited by the performance of hoses and hose assemblies. The hoses are not suitable for use with castor oil-based and ester-based fluids. Hoses and hose assemblies may not be operated outside the limits of this standard. Requirements for hydraulic hoses for underground mining are standardized in separate standards.

Hoses are not suitable for use with castor oil-based or ester-based fluids. Hoses and hose assemblies may not be operated outside the limits of this standard. Hydraulic hose requirements for underground mining are standardized in a separate standard.

Hoses shall consist of an oil and water resistant synthetic rubber liner, spiral layers of steel wire wound in alternating directions and an oil and weather resistant synthetic rubber cap. Each spiral wire layer will be separated by an insulating synthetic rubber layer.

Hose assemblies shall only be manufactured with hose fittings whose functionality has been verified. When measured according to EN ISO 4671, the diameters of the hoses must correspond to the values ​​given.
