24、(E) 4 Introduction This document 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 any stage. The frequenc
25、ies of the different types of pressure vessel inspection are given by the relevant international regulations concerning the transport of dangerous goods. 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
26、 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 materials, etc. NOTE Annex B indicates which clauses in this standar
27、d 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 standard develop an environmental management policy. For guidance, see EN ISO 14001. It has bee
28、n assumed in the drafting of this document that the execution of its provisions is entrusted to appropriately qualified and experienced people. DIN EN 14334:2015-01 EN 14334:2014 (E)5 1 Scope This European Standard specifies minimum requirements for the inspection and testing of the LPG road tanker,
29、 which includes its pressure vessel, accessories and vehicle LPG equipment. This European Standard does not specify requirements for the initial inspection (after manufacture) of a pressure vessel, see EN 12493, or for service equipment on the road tanker, see EN 12252. This European Standard does n
30、ot apply to compartmented road tankers. NOTE 1 There is no upper size limit for the pressure vessel as this will be determined by the gross vehicle weight limitation. NOTE 2 For inspection and testing requirements of equipment other than the pressure vessel, accessories and vehicle LPG equipment, se
