This European Standard was approved by CEN on 19 October 2025.

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
Centre has the same status as the official versions.

European foreword
This document (EN 1761:2025) has been prepared by Technical Committee CEN/TC 218 “Rubber and
plastics hoses and hose assemblies”, the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by May 2026, and conflicting national standards shall be
withdrawn at the latest by May 2026.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 1761:1999.
— modification of the Scope by introducing a note regarding on how to proceed with other
temperatures and working pressures;
— in Table 1 adoption of the Dimensions 80 mm and 125 mm;
— in Table 3 modification of the entries for “Proof pressure min.” and “Burst pressure min.”;
— introduction of a new Annex A for Test frequency for type tests and routine tests;
— add the option of using water as a test liquid in place of Liquid F for the Flammability Test in
Annex D.
This document is based on ISO 2929, BS 3492 and the German military standard VG 95955.
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 the requirements for two types of rubber hoses and rubber hose assemblies for
loading and discharge of liquid hydrocarbon fuels with a maximum working pressure of 10 bar
(1,0 MPa).
Both types of hose are designed for:
a) use with hydrocarbon fuels, having an aromatic hydrocarbon content not exceeding 50 % by
volume and containing oxygenated compounds up to 15 %;
b) operation within the temperature range of −30 °C to +70 °C, undamaged by climatic conditions of
−50 °C to 70 °C when stored in static conditions.
This document is not applicable to hoses and hose assemblies for LPG, aviation fuel systems, fuel station
systems and marine applications.

4 Types
Hoses shall be one of the following types:
a) type D: delivery hose;
b) type SD: suction and delivery hose, helix reinforced.
Both these types can be either:
1) electrically bonded, designated and marked “M” type; or
2) electrically conductive, using a conductive rubber layer, designated and marked “Ω” type.
5 Materials and construction
If mandrel built, particulate type, release agents shall not be used.
The hose shall be uniform in quality and free from porosity, airholes, foreign inclusions and other
defects.
The hose shall consist of the following:
a) a lining of synthetic rubber resistant to hydrocarbon fuels;
b) a reinforcement of layers of woven, braided or spirally wound textile material;
c) an embedded helix reinforcement (type SD only);
d) two or more low resistance electrical bonding wires (type “M” only);
e) an outer cover of synthetic rubber, resistant to abrasion, outdoor exposure and hydrocarbon fuels.
