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.

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].
