European foreword

This document (prEN 13760:2020) has been prepared by Technical Committee CEN/TC 286 “LPG

equipment and accessories”, the secretariat of which is held by NSAI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 13760:2003.

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 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 DN

and PS with a limit of 1 000.

— Because the design pressure (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.
