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.The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
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 held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

10.5.2.10 High temperature creep test
In designs where glass or aramid fibre has a load sharing application, one cylinder shall be tested in
accordance with A.18.A.6 Leak-before-break (LBB) test
Three finished cylinders shall be pressure cycled between less than or equal to 20 bar and greater than or
equal to 1.5 × working pressure, at a rate not exceeding 10 cycles per minute in accordance with A.13.
All cylinders shall either fail by leakage or exceed 45 000 pressure cycles.A.7 Extreme temperature pressure cycling
Finished cylinders, with the composite wrapping free of any protective coating, shall be cycle tested:
a) condition for more than 48 h at zero pressure, 65 °C or higher, and 95 % or greater relative humidity.
The intent of this relative humidity requirement shall be deemed met by spraying with a fine spray or
mist of water in a chamber held at a minimum 65 °C;b) hydrostatically pressurize for 500 cycles multiplied by the specified service life in years between less
than or equal to 20 bar and greater than or equal to 260 bar at 65 °C or higher, and 95 % or greater
relative humidity;c) condition the cylinder and fluid at – 40 °C or lower as measured in the fluid and on the cylinder surface;
d) pressurize from less than or equal to 20 bar to greater than or equal to 200 bar for 500 cycles multiplied
by the specified service life in years at – 40 °C or lower. Adequate recording instrumentation shall be
provided to ensure the minimum temperature of the fluid is maintained during the low temperature
cycling. At no time during the pressure cycling shall the fluid be warmer than – 40 °C.
The pressure cycling rate of b) shall not exceed 10 cycles per minute. The pressure cycling rate of d) shall
not exceed 3 cycles per minute unless a pressure transducer is installed directly within the cylinder. All
temperature, pressure, and relative humidity values shall be recorded at least every 6 seconds. Cycles that
fall outside the limits of the pressure, humidity and temperature values, shall be discounted from the total
requirement.During this pressure cycling, the cylinder shall show no evidence of rupture, leakage or fibre unravelling.
Following pressure cycling at extreme temperatures, cylinders shall be hydrostatically pressured to
failure in accordance with A.12, and achieve a minimum burst pressure of 85 % of the minimum design
burst pressure. For type 4 designs, prior to the hydrostatic burst test the cylinder shall be leak tested in
accordance with A.10.A.9 Coating tests
These tests are intended to validate a coating system that can be used for the same coating on other designs.
An alternative corrosion test for severe exposure conditions is provided in Annex H.
Coatings shall be evaluated using:f) Adhesion testing, in accordance with ASTM D3359, using method A or B, as appropriate. The coating
shall exhibit an adhesion rating of either 4A or 4B, as appropriate.4 © ISO 2020 – All rights reserved
