25、2013ISO 11439:2013(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a s
26、ubject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission
27、(IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical commit
28、tees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be
29、held responsible for identifying any or all such patent rights.ISO 11439 was prepared by Technical Committee ISO/TC 58, Gas cylinders, Subcommittee SC 3, Cylinder design.This second edition cancels and replaces the first edition (ISO 11439:2000), which has been technically revised. In addition to ed
30、itorial improvements, the principal technical difference between the first and second editions is the clarification and alteration of the “Change of Design” requirements for the various cylinder types.

31、n-board storage of fuel for natural gas vehicle service are required to be light-weight, at the same time maintaining or improving on the level of safety currently existing for other pressure vessels.Owners or users of cylinders designed to this International Standard should note that the cylinders
32、are designed to operate safely if used in accordance with specified service conditions for a specified finite service life only. The expiry date is marked on each cylinder and it is the responsibility of owners and users to ensure that cylinders are not used after that date, and that they are inspec
33、ted in accordance with the manufacturers instructions.Users of this International Standard are encouraged to consider the environmental impacts associated with performing certain tests.vi ISO 2013 All rights reservedBS EN ISO 11439:2013Gas cylinders High pressure cylinders for the on-board storage o
34、f natural gas as a fuel for automotive vehicles1 ScopeThis International Standard specifies minimum requirements for light-weight refillable gas cylinders intended only for the on-board storage of high pressure compressed natural gas as a fuel for automotive vehicles to which the cylinders are to be
35、 fixed. The service conditions do not cover external loadings that can arise from vehicle collisions, etc.This International Standard covers cylinders of any seamless steel, seamless aluminium alloy or non-metallic material construction, using any design or method of manufacture suitable for the spe
36、cified service conditions. This International Standard does not cover cylinders of stainless steel. Although this standard uses 200 bar as a reference working pressure, other working pressures can be used.Cylinders covered by this International Standard are designated Type 1, Type 2, Type 3 and Type
