European foreword
This document (EN 13953:2020) has been prepared by Technical Committee CEN/TC 286 “LPG
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 June 2021, and conflicting national standards shall be
withdrawn at the latest by June 2021.
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 13953:2015.
The major changes to this revision include:
— addition of water capacity range in the scope;
— addition of requirements for rubber material;
— change to the nominal set pressure;
— clarification to discharge capacity test;
— clarification to endurance test
This document has been submitted for reference in
— the RID and/or
— the technical annexes of the ADR
NOTE These regulations take precedence over any clause of this standard. It is emphasized that RID/ADR are
being revised regularly at intervals of two years which may lead to temporary non-compliances with the clauses of
this standard.”
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,

Introduction
This document calls for the use of substances and procedures that may be injurious to health and/or the
environment if adequate precautions are not taken. It refers only to technical suitability. It does not
absolve the user from their legal obligations at any stage.
Protection of the environment is a key political issue in Europe and elsewhere around the world.
Protection of the environment in this document is understood in a very broad sense. The phrase is used,
for example, in relation to the total life-cycle aspects of a product on the environment, including
expenditure of energy, and during all phases of its existence, from mining of raw materials, to fabrication,
packaging, distribution, use, scrapping, recycling of materials, etc.
It is essential that provisions be restricted to a general guidance. Limit values are specified in national
laws.
Protection of the environment is a key political issue in Europe and elsewhere, for CEN/TC 286 this is
covered in CEN/TS 16765 [2], LPG equipment and accessories – Environmental considerations for
CEN/TC 286 standards, and this Technical Specification should be read in conjunction with this standard.
It has been assumed in the drafting of this document that the execution of its provisions is entrusted to
appropriately qualified and experienced people.
All pressures are gauge pressures unless otherwise stated.
In this European Standard the unit bar is used, due to its universal use in the field of technical gases. It
should, however, be noted that bar is not an SI unit, and that the corresponding SI unit for pressure is Pa
5 5 2
(1 bar = 10 Pa = 10 N/m ).
NOTE This document requires measurement of material properties, dimensions and pressures. All such
measurements are subject to a degree of uncertainty due to tolerances in measuring equipment, etc. It may be
beneficial to refer to the leaflet “measurement uncertainty leaflet” SP INFO 2000 27 [3].
1 Scope
This document specifies the design, testing and marking requirements for spring loaded pressure relief
valves (PRV), for use in liquefied petroleum gas (LPG) cylinders of water capacity of 0,5 l up to and
including 150 l.
These PRVs can be either an integral part of a cylinder valve (see EN ISO 14245 [4] and EN ISO 15995
[5]) or a separate device.
