This European Standard was approved by CEN on 13 March 2026.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this
European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references
concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN
member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by
translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management

identical text or by endorsement, at the latest by October 2026, and conflicting national standards shall
be withdrawn at the latest by October 2026.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 853:2015.
This document includes the following significant technical changes with respect to EN 853:2015:
— scope changed (nominal bore extended: 5 to 76);
— 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,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and the United
Kingdom.
1 Scope
This document specifies requirements for four types of wire braid reinforced hoses and hose assemblies
of nominal bore from 5 to 76: Types 1SN, 2SN, 1ST and 2ST. They are suitable for use with:
— hydraulic fluids in accordance with ISO 6743-4 with the exception of all flame retardant HFD fluids
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.
The hoses are not suitable for use with castor oil based and 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 other documents.

4 Types of hoses
Four types of hoses are specified, distinguished by their construction and maximum working pressure:
1) Type 1ST – hoses with a single braid of wire reinforcement;
2) Type 2ST – hoses with two braids of wire reinforcement;
3) Type 1SN – hoses with a single braid of wire reinforcement;
4) Type 2SN – hoses with two braids of wire reinforcement.
Types 1SN and 2SN shall be of the same reinforcement construction as types 1ST and 2ST, except that
they shall have thinner covers designed to assemble with fittings that do not require removal of the cover
or a portion of the cover.
For new designs of braided hoses in hydraulic fluid power applications, hose types 1SN and 2SN, specified
in this document, and 1SC and 2SC, specified in EN 857, shall be used. Hose types 1ST and 2ST shall not
be used for new designs in hydraulic fluid power applications.
Hoses and hose assemblies shall 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, one or two layers of high tensile
steel wire braid and an oil and weather resistant rubber cover. Each 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.
