23、 57 Bibliography 59 BS EN 14140:2014EN 14140:2014 (E) 4 Foreword This document (EN 14140:2014) 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 nati
24、onal standard, either by publication of an identical text or by endorsement, at the latest by June 2015 and conflicting national standards shall be withdrawn at the latest by June 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent righ
25、ts. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 14140:2003+A1:2006. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. This European Standard
26、has been submitted for reference into: the RID 11; and the technical annexes of the ADR 12. NOTE These regulations take precedence over any clause of this European Standard. It is emphasised that RID/ADR/ADN are being revised regularly at intervals of two years which may lead to temporary non-compli
27、ances with the clauses of this European Standard. The major changes to this revision include: restructure of standard; the addition of requirements for hot air balloon cylinders; an update on the terminology; the addition of requirements for over-moulded cylinders; the addition of the environmental
28、checklist, Annex D. 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 Ma

BS EN 14140:2014EN 14140:2014 (E) 5 Introduction This European Stan
30、dard 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. It has been assumed in the drafting of th
31、is European Standard that the execution of its provisions is entrusted to appropriately qualified and experienced people. This European Standard permits the use of new and higher strength steels and has the potential for cylinders to have a wall thickness thinner than the minimum wall thickness rela
32、ted to diameter, when compared with cylinders in accordance with EN 1442. These changes in technology are justified by requiring a series of performance tests, including impact testing, to demonstrate the adequacy of the calculated pressure thickness for service and transport considerations Referenc
33、e should also be made to EN 1439 and EN 1440, which requires the cylinder manufacturer to perform additional tests to determine the rejection limits for in-service damage and to include these limits in the documentation for the cylinder. Protection of the environment is a key political issue in Euro
34、pe 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
35、, from mining of raw materials, to fabrication, packaging, distribution, use, scrapping, recycling of materials, etc. Annex D comprises an environmental checklist which highlights the clauses of this European Standard that address environmental aspects. It is recommended that manufacturers develop a
36、n environmental management policy. For guidance see EN ISO 14000 series, 6, 7 and 8. Provisions need to be restricted to a general guidance. Limit values are specified in national laws. All pressures are gauged unless otherwise stated. NOTE This European Standard requires measurement of material pro
37、perties, 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 14. BS EN 14140:2014EN 14140:2014 (E) 6 1 Scope This European S
38、tandard specifies the minimum requirements for the design, construction and testing during manufacture of transportable refillable welded steel Liquefied Petroleum Gas (LPG) cylinders, of water capacity from 0,5 l up to and including 150 l, exposed to temperatures of -20 C to +65 C. It allows altern
39、ative design and construction methods to those required in EN 1442, including coated cylinders, over-moulded cylinders and cylinders for hot air balloons. This European Standard applies only to pressure receptacles with a circular cross-section. This European Standard does not include the equipping
40、of the cylinders with valves and other service equipment. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
