This European Standard shall be given
31、 the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2017, and conflicting national standards shall be withdrawn at the latest by November 2017. Attention is drawn to the possibility that some of the elements of this document may
32、 be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1442:2006+A1:2008. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. All stage
33、s of the manufacture, distribution and disposal of these cylinders may have an effect on the environment. CEN/TS 16765 1 sets out environmental considerations for this European Standard. This European Standard has been submitted for reference into the RID 4 and/or in the technical annexes of the ADR
34、 5. Therefore the standards listed in the normative references and covering basic requirements of the RID/ADR not addressed within the present standard are normative only when the standards themselves are referred to in the RID 4 and/or in the technical annexes of the ADR 5. NOTE These regulations t
35、ake precedence over any clause of this European Standard. It is emphasized that RID/ADR are being revised regularly at intervals of two years which may lead to temporary non-compliances with the clauses of this European Standard. This European Standard has been extensively re-formatted to align with
36、 other more recent LPG cylinder standards. The main technical changes include: the inclusion of over-moulded cylinders; and re-establishing 50 bar as the minimum burst pressure. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bou

BS EN 1442:2017EN 1442:2017 (E) 6 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 onl
39、y to technical suitability and does not absolve the user from legal obligations relating to health and safety at any stage. It has been assumed in the drafting of this European Standard that the execution of its provisions is entrusted to appropriately qualified and experienced people. All pressures
40、 are gauge pressures unless otherwise stated. NOTE This European Standard requires measurement of material properties, dimensions and pressures. All such measurements are subject to a degree of uncertainty due to tolerances in measuring equipment, etc. It may be beneficial to refer to the leaflet “m
