28、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of an identical text or by endorsement, at the latest by November 2014 and conflicting national standards shall be withdrawn at the latest by November 2014. Attention is drawn to the possibility that some

29、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 14893:2006. The major changes in this revision include: an update of the terminology; and the addition of

30、an environmental checklist, Annex H. 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 12; and the technical annexes of the ADR 13. NOTE These regulati

31、ons take precedence over any clause of this European Standard. It is emphasized 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. According to the CEN-CENELEC Internal Regulations, the nation

32、al 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, Lithu

33、ania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. DIN EN 14893:2014-09EN 14893:2014 (E) 6 Introduction This European Standard calls for the use of substances and procedures that may be injurious to

34、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 around the world. Protection of the env

35、ironment in this document is understood in a very broad sense. The phrase is used, for example, in relation to the total life-cycle environmental aspects of a product, including expenditure of energy, and during all phases of its existence, from mining of raw materials to fabrication, packaging, dis

36、tribution, use, scrapping, recycling of materials, etc. Annex H 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. For guidance, see EN ISO 14

37、000 series, 6, 7 and 8. 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 pressure

38、s are gauge 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 “measuremen

39、t uncertainty leaflet” SP INFO 2000 27 16. DIN EN 14893:2014-09EN 14893:2014 (E) 7 1 Scope This European Standard specifies the minimum requirements for the material, design, construction, workmanship, equipping, inspection and testing at manufacture of transportable, refillable welded steel pressur
