Foreword
ISO (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 subject 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 (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given 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 possibility 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.
International Standard ISO 11439 was prepared by Technical Committee ISO/TC 58, Gas cylinders, Subcommittee
SC 3, Cylinder design.
Annexes A and B form a normative part of this International Standard. Annexes C to H are for information only.

ISO 11439:2000(E)
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 improving 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 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) requiring manufacturers to have a comprehensive quality system documented and implemented;
g) requiring periodic re-inspection and, if necessary, retesting in accordance with the manufacturer’s instructions;
h) requiring manufacturers to specify as part of their design, the safe service life of their 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 burst 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 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 inspected in accordance with the manufacturer’s instructions.
