What is BS EN 856 - Rubber hose assemblies about?
BS EN 856 is an International Standard that focuses on rubber hoses and hose assemblies.
BS EN 856 gives the best specifications for rubber-covered spiral wire reinforced hydraulic type.
BS EN 856 specifies requirements for four types of rubber-covered spiral wire reinforced hydraulic hoses and hose assemblies of the nominal bore from 6 to 51: Types 4SP, 4SH, R12 and R13. They are all suitable for use with:
- Hydraulic fluids by ISO 6743-4 except 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
Note: BS EN 856 does not include requirements for end fittings. It is limited to the performance of hoses and hose assemblies.
Who is BS EN 856 - Rubber hose assemblies for?
BS EN 856 on rubber hoses and hose assemblies is useful for:
- Rubber and plastic hoses manufacturers and suppliers   
- PVC hose pipe manufacturers and suppliers   
- Entities dealing with plastic hose assembly and hoses    
- Test providers for plastic and rubber hoses                                                               
Why should you use BS EN 856 - Rubber hose assemblies?
Rubber hoses are designed for specific fluid, temperature, and pressure ranges and are provided with various specifications.
BS EN 856 provides you specifications for rubber-covered spiral wire reinforced hydraulic type of hoses assemblies that help you to check whether they will withstand the differential pressure encountered in service resulting from reduced pressure within the hose or hose assembly.
The test methodologies given in BS EN 856 enable you to verify the characteristics of four types of rubber-covered spiral wire reinforced hydraulic hoses and hose assemblies of the nominal bore. This contributes to manufacturing and maintaining the high quality and efficient functioning of rubber, plastic hose, and hoses assemblies.
