22、ld 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of an identical text or by endorsement, at the latest by September 2013, and conflicting national standards shall be withdrawn at the latest by September 2013. Attention is drawn to the possibi

23、lity 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 14678-1:2006+A1:2009. This document has been prepared under a mandate given to CEN by the E

24、uropean Commission and the European Free Trade Association, and supports essential requirements of EU Directive. For relationship with EU Directive, see informative Annex ZA, which is an integral part of this document. Differences between this document and EN 14678-1:2006+A1:2009 include: The additi

According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,

28、 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, Switzerland, Turkey and the U

29、nited Kingdom. BS EN 14678-1:2013EN 14678-1:2013 (E) 5 Introduction This document is a type C standard as stated in EN ISO 12100:2010. When provisions of this type C standard differ from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the

30、provisions of the other standards. This European Standard calls for the use of substances and procedures that may be injurious to health if adequate precautions are not taken. It refers only to technical suitability and does not absolve the user from legal obligations relating to health and safety a

31、t any stage. Protection of the environment is a key political issue in Europe and elsewhere. Protection of the environment is taken in a very broad sense. What is meant is the total life cycle aspects of, e.g. a product on the environment, including expenditure of energy and during all phases from m

32、ining of raw materials, fabrication, packaging, distribution, use, scrapping, recycling of materials, etc. NOTE Annex D indicates which clauses in this European Standard address environmental issues. Clauses addressing environmental issues are restricted to a general guidance. Limiting values can be

33、 specified in national laws. It is recommended that companies using this European Standard develop an environmental management policy. For guidance see ISO 14000 series 15, 16 and 17. It has been assumed in the drafting of this European Standard that the execution of its provisions is entrusted to a

34、ppropriately qualified and experienced people. All pressures are gauge unless otherwise specified. The PED, Directive 97/23/EC 20, applies to any assembly with a component defined as category II or higher in this Directive: Article 1, 3.6 of the PED excludes equipment classified as no higher than ca

35、tegory I under article 9 if it is covered by Directive 94/9/EC (ATEX). The category I limit is defined in Annex II Table 6 of the PED. It applies to piping for liquids whose vapour pressure at the maximum allowable temperature is greater than 0,5 bar (50 kPa) above DN 100 or, in the case of maximum

36、allowable pressures greater than 10 bar (1 kPa), is above the product of DN and PS of 1 000. Because the maximum allowable pressure (PS) in this document is 25 bar (2 500 kPa) and the DN of the intended piping is less than 40, the product of DN and PS of 1 000 in Table 6 of the PED is not reached. T

37、he category I limit for vessels is defined in Annex II Table 1 of the PED. It also applies to vessels for liquids whose vapour pressure at the maximum allowable temperature is greater than 0,5 bar (50 kPa) above volumes (V) of 1 l up to a pressure of 200 bar or, in the case of the product of V and P

38、S of 50. Because the maximum allowable pressure (PS) in this document is 25 bar (2 500 kPa) and if the V of the intended vessel is less than 2 l, the product of V and PS of 50 in Table 1 of the PED is not reached. BS EN 14678-1:2013EN 14678-1:2013 (E) 6 1 Scope This European Standard covers the requ

39、irements for the design, manufacture, testing and marking of LPG dispensers for automotive LPG filling stations with a maximum allowable pressure of 25 bar (2 500 kPa), where the piping has a maximum DN 40 and any vessel fitted has a volume less than 2 l. This European Standard covers the requiremen

40、ts for the LPG parts in multi-fuel dispensers. This European Standard does not cover dispensers with integral pumps. This European Standard may also be used for piping greater than DN 40 and/or vessels greater than 2 l, but then the PED 20 should also be consulted. This European Standard does not in

41、clude any requirement for metering performance. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
