28、pean 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 national standard, either by publication of an identica

29、l text or by endorsement, at the latest by June 2015 and conflicting national standards shall be withdrawn at the latest by June 2015.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 rights. CEN and/or CENELEC shall not be held responsibl

30、e 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 has been submitted for reference into: the RID 11;

31、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-compliances with the clauses of this European Standard. T

32、he 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 checklist, Annex D. According to the CEN-CENELEC In

33、ternal 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,

34、 Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. EN 14140:2014 + AC:2015 (E) DIN EN 14140:2017-01 5 Introduction This European Standard calls for the use of substances

35、 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 this European Standard that the execut

36、ion 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 related to diameter, when compared with

37、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 Reference should also be made to EN 1439 and

38、 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 Europe and elsewhere around the world. P

39、rotection 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 f

40、abrication, 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 an environmental management policy. F

41、or 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 properties, dimensions and pressures. A

42、ll 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. EN 14140:2014 + AC:2015 (E) DIN EN 14140:2017-01 6 1 Scope This European Standard specifies the

43、 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 alternative design and cons

44、truction 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 of the cylinders with

45、 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.
