European foreword
This document (EN 13760:2021) has been prepared by Technical Committee CEN/TC 286 “Liquefied
petroleum gas equipment and accessories”, the secretariat of which is held by NSAI.
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 2022, and conflicting national standards shall be
withdrawn at the latest by May 2022.
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 13760:2003.
This document includes the following significant technical changes with respect to EN 13760:2003:
— Updated normative references;
— Revised definitions;
— Revised test procedures;
— Removal of re-testing step from each test procedure;
— Addition of oxygen ageing test;
— Revised critical dimensions of Figure B.2;
— Revised Annex ZA.
This document has been prepared under a standardization request given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of
EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
document.
This document does not deal with the essential safety requirements of the DIRECTIVE 2014/68/EU of the
European Parliament and of the Council of 15 May 2014 on the harmonization of the laws of the Member
States relating to the making available on the market of pressure equipment.
This document addresses the essential health and safety requirements of DIRECTIVE 2014/34/EU OF
THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 26 February 2014 on the harmonization of the
laws of the Member States relating to equipment and protective systems intended for use in potentially
explosive atmospheres.
In the Pressure Equipment Directive (PED) the nozzle is classified as a “pressure accessory”. It is intended
to be connected to a hose, which is classified as “piping”.
— The category 1 limit is defined in Annex 2 Table 6 of the PED and is a function of the product of
nominal size (DN) and maximum allowable pressure (PS) with a limit of 1 000.
— Because PS in this document is 2 500 kPa and the DN of the intended hose is less than 40, the figure
of 1 000 in Table 6 is not reached.
