BS EN 14334:2014EN 14334:2014 (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

21、legal obligations relating to health and safety at any stage. The frequencies 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 els

22、ewhere. 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 mining of raw materials, fabrication, packaging, distribution, use, scrapping, recycli

23、ng of materials, etc. NOTE Annex B indicates which clauses in this 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 standard develop an e

24、nvironmental management policy. For guidance, see EN ISO 14001. It has been assumed in the drafting of this document that the execution of its provisions is entrusted to appropriately qualified and experienced people. BS EN 14334:2014EN 14334:2014 (E) 5 1 Scope This European Standard specifies minim

25、um requirements for the inspection and testing of the LPG road tanker, 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 equ

26、ipment on the road tanker, see EN 12252. This European Standard does not 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 oth

27、er than the pressure vessel, accessories and vehicle LPG equipment, see applicable regulations. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
