EN 13110:2012+A1:2017 (E) 5 European foreword This document (EN 13110:2012+A1:2017) 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of an identical text or by endorsement, at the latest by July 2017, and conflicting national standards shall be withdrawn at the latest by July 2017. This document includes Amendment 1 approved by CEN on 03 January 2017. This document supersedes !EN 13110:2012". The start and finish of text introduced or altered by amendment is indicated in the text by tags ! ". Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13110:2002. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). This standard has been submitted for reference into the RID and/or in the technical annexes of ADR (see [9] and [8]). The main technical changes to this revision include the addition of: — reference to the latest welding standards; — the introduction of radioscopy as a permitted alternative to radiographic examination of welds; — simplification of the marking requirements by reference to EN 14894; and — environmental considerations recorded in Annex B. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 13110:2012+A1:2017 (E) 6 Introduction This European Standard 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. This Technical Specification should be read in conjunction with this European Standard." It is recommended that manufacturers 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 European Standard that the execution of its provisions is entrusted to appropriately qualified and experienced people. All pressures are gauged unless otherwise stated. NOTE This European Standard 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 [11].
