21、N 14678-3:2013 (E) 4 Introduction 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 at

22、 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 mi

23、ning of raw materials, fabrication, packaging, distribution, use, scrapping, recycling of materials, 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

24、specified in national laws. It is recommended that companies using this European Standard develop an environmental management policy. For guidance see EN ISO 14021 3, EN ISO 14024 4 and EN ISO 14025 5. BS EN 14678-3:2013EN 14678-3:2013 (E) 5 1 Scope This European Standard covers the equipment and in

25、stallation requirements for LPG refuelling installations, which are required to safely dispense 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 Sta
