25、:2014EN 14893:2014 (E) 5 Foreword This document (EN 14893:2014) has been prepared by Technical Committee CEN/TC 286 “LPG 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

26、l text or by endorsement, at the latest by November 2014 and conflicting national standards shall be withdrawn at the latest by November 2014.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 of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held re

27、sponsible 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 an environmental checklist, Annex H. This document has been prepared under a mandate given to CEN by the Euro

28、pean 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 regulations take precedence over any clause of this European Standard. It is emphasized that RID/ADR/ADN are being re

29、vised 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 national standards organizations of the following countries are bound to implement this European Standard: Austria,

30、 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, Slovakia, Slovenia, Spain, Sweden, S

31、witzerland, Turkey and the United Kingdom. BS EN 14893:2014EN 14893:2014 (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

32、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 environment in this document is understood in a very broad sense. The phrase is used, for example, in relation to th

33、e 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, distribution, use, scrapping, recycling of materials, etc. Annex H comprises an environmental checklist which highli

34、ghts 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 14000 series, 6, 7 and 8. Provisions need to be restricted to a general guidance. Limit values are specified in nat

35、ional 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 gauge unless otherwise stated. NOTE This European Standard requires measurement of material properties, dim

36、ensions 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 16.
