25、tandards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International
26、organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules gi
27、ven in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees 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 possibil
28、ity that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

29、r design. Annexes A and B form a normative part of this International Standard. Annexes C to H are for information only. EN ISO 11439:2000 v Introduction Cylinders for the on-board storage of fuel for natural gas vehicle service are required to be light-weight, at the same time maintaining or improv
30、ing on the level of safety currently existing for other pressure vessels. These requirements are achieved by: a) specifying service conditions precisely and comprehensively as a firm basis for both cylinder design and use; b) using an appropriate method to assess cyclic pressure fatigue life and to
31、establish allowable defect sizes in metal cylinders or liners; c) requiring design qualification tests; d) requiring non-destructive testing and inspection of all production cylinders; e) requiring destructive tests on cylinders and cylinder material taken from each batch of cylinders produced; f) r
32、equiring manufacturers to have a comprehensive quality system documented and implemented; g) requiring periodic re-inspection and, if necessary, retesting in accordance with the manufacturers instructions; h) requiring manufacturers to specify as part of their design, the safe service life of their
33、cylinders. Cylinder designs that meet the requirements of this International Standard: a) will have a fatigue life which exceeds the specified service life; b) when pressure cycled to failure, will leak but not rupture; c) when subject to hydrostatic burst tests, will have factors of “stress at burs
34、t pressure” over “stress at working pressure” that exceed the values specified for the type of design and the materials used. Owners or users of cylinders designed to this International Standard should note that the cylinders are designed to operate safely if used in accordance with specified servic
35、e 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 inspected in accordance with the manufacturers instructions.

36、N ISO 11439:2000 1 Gas cylinders High pressure cylinders for the on-board storage of natural gas as a fuel for automotive vehicles 1 Scope This International Standard specifies minimum requirements for serially produced light-weight refillable gas cylinders intended only for the on-board storage of
37、high pressure compressed natural gas as a fuel for automotive vehicles to which the cylinders are to be fixed. The service conditions do not cover external loadings which may arise from vehicle collisions, etc. This International Standard covers cylinders of any steel, aluminium or non-metallic mate
38、rial construction, using any design or method of manufacture suitable for the specified service conditions. This International Standard does not cover cylinders of stainless steel or of welded construction. Cylinders covered by this International Standard are designated as follows: CNG-1 Metal CNG-2

40、SO 9809-1, ISO 9809-2, ISO 9809-3 and ISO 7866 can be used for this service provided these designs meet additional requirements as specified in this International Standard. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute p
