European foreword
This document (EN 13110:2022) 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 June 2023, and conflicting national standards shall be
withdrawn at the latest by June 2023.
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 13110:2012+A1:2017.
EN 13110:2022 includes the following significant technical changes with respect to
EN 13110:2012+A1:2017:
— revision to 5.7 Neck design; and
— revision to 5.9 Valve protection.
This document has been submitted for reference in:
— the RID [10]; and/or
— the technical annexes of the ADR [9].
NOTE These regulations take precedence over any clause of this document. It is emphasized that RID/ADR are
being revised regularly at intervals of two years which might lead to temporary non-compliances with the clauses
of this document.
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,

Introduction
This document calls for the use of substances and procedures that can 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. For CEN/TC 286 this is
covered in CEN/TS 16765 [2] and this Technical Specification is to be read in conjunction with this
document. The Technical Specification provides guidance on the environmental aspects to be considered
regarding equipment and accessories produced for the LPG industry and the following is addressed:
a) design;
b) manufacture;
c) packaging;
d) use and operation; and
e) disposal.
Users are advised to develop an environmental management policy. For guidance see ISO 14000 series.
Provisions need to be restricted to a general guidance. Limit values are specified in national laws.
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 gauged unless otherwise stated.
In this document 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 (1
5 5 2
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 might be
beneficial to refer to the leaflet “measurement uncertainty leaflet” SP INFO 2000 27 [12].

European foreword
This document (prEN 13110:2021) has been prepared by Technical Committee CEN/TC 286 “Liquefied
petroleum gas equipment and accessories”, the secretariat of which is held by NSAI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 13110:2012+A1:2017.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association.
This document has been submitted for reference in:
⎼ the RID [9]; and/or
⎼ the technical annexes of the ADR [8].
NOTE These regulations take precedence over any clause of this document. It is emphasized that RID/ADR are
being revised regularly at intervals of two years which might lead to temporary non-compliances with the clauses
of this document.
The main technical change to this revision includes the following:

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. For CEN/TC 286 this is
covered in CEN/TS 16765 and this Technical Specification should be read in conjunction with this
document. The Technical Specification provides guidance on the environmental aspects to be considered
regarding equipment and accessories produced for the LPG industry and the following is addressed:
a) design;
b) manufacture;
c) packaging;
d) use and operation; and
e) disposal.
Users are advised to develop an environmental management policy. For guidance see ISO 14000 series.
Provisions need to be restricted to a general guidance. Limit values are specified in national laws.
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 gauged unless otherwise stated.
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 might be
beneficial to refer to the leaflet “measurement uncertainty leaflet” SP INFO 2000 27 [11].
