DIN EN 14678-3:2013-03 EN 14678-3:2013 (E) 4 Introduction This European Standard calls for the use of substances and

23、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 at any stage. Protection of the environment is a key political issue in Europe and elsewhere. P

24、rotection 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 mining of raw materials, fabrication, packaging, distribution, use, scrapping, recycling of mat

25、erials, etc. NOTE Annex B indicates which clauses in this European Standard address environmental issues. Clauses addressing environmental issues are restricted to a general guidance. Limiting values can be specified in national laws. It is recommended that companies using this European Standard dev

26、elop an environmental management policy. For guidance see EN ISO 14021 3, EN ISO 14024 4 and EN ISO 14025 5. DIN EN 14678-3:2013-03 EN 14678-3:2013 (E) 5 1 Scope This European Standard covers the equipment and installation requirements for LPG refuelling installations, which are required to safely d

27、ispense LPG at commercial and industrial premises. This European Standard does not cover public LPG filling stations. This European Standard does not cover nautical LPG refuelling installations. This European Standard does not cover on-site and off-site safety distances. 2 Normative references The f
