EN 856:2015+AC:2019:
— EN 853, EN 854, EN 856 and EN 857 have been aligned;
— updated normative references;
— Table 7 added;
— former Annex A deleted;
— former Annex C deleted.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,

Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and the United
Kingdom.
1 Scope
This document specifies requirements for four types of rubber-covered spiral wire reinforced hydraulic
hoses and hose assemblies of nominal bore from 6 to 51: Types 4SP, 4SH, R13 and R15. They are suitable
for use with:
— hydraulic fluids covered in ISO 6743-4 with the exception of all flame retardant HFD fluids at
temperatures ranging from −40 °C to +100 °C for types 4SP and 4SH and −40 °C to +120 °C for
types R13 and R15;
— water-based fluids at temperatures ranging from −40 °C to 70 °C;
— water fluids at temperatures ranging from 0 °C to 70 °C.
The hoses are not suitable for use with castor oil based nor ester-based fluids.
This document does not include requirements for end fittings. It is limited to the performance of hoses
and hose assemblies.
NOTE Requirements for hydraulic hoses for underground mining are covered in a different document.

4 Types of hose
Four types of hose are specified, distinguished by their construction and maximum working pressure:
1) Type 4SP – a 4-steel wire spiral medium pressure hose;
2) Type 4SH – a 4-steel wire spiral extra high pressure hose;
3) Type R13 – a multiple steel wire spiral heavy duty high temperature hose – high pressure rating
4) Type R15 – a multiple steel wire spiral heavy duty high temperature hose – high pressure rating.
Hoses and hose assemblies are not be operated outside the limits of this document.
5 Materials and construction
5.1 Hoses
Hoses shall consist of an oil and water resistant synthetic rubber lining, spiral plies of steel wire wrapped
in alternating directions, and an oil and weather resistant synthetic rubber cover. Each spiral wire ply
shall be separated by an insulating layer of synthetic rubber.
5.2 Hose assemblies
Hose assemblies shall only be manufactured with those hose fittings whose functionality as a defined
hose and fitting combination has been verified in accordance with 7.1, 7.3, 7.4 and 7.5 of this document.
The manufacturer’s instructions shall be followed for the preparation and fabrication of hose assemblies.
6 Dimensions
6.1 Diameters and concentricity
The diameters of the hoses shall be measured in accordance with EN ISO 4671 and as such shall conform
to the values in Table 1.
