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).

The committee responsible for this document is ISO/TC 58, Gas cylinders, Subcommittee SC 4, Operational requirements for gas cylinders.

This second edition cancels and replaces the first edition (ISO 11623:2002), which has been technically revised with the following changes:

— up-to-date terminology particularly for the various types of composite cylinders;
— up-to-date normative references for steel and aluminium-alloy liner materials;
— list defects according to severity with an additional set of acceptance/rejection criteria;
— replacement of the procedure regarding obstructed cylinder valve (former Annex A) with a reference to ISO 25760;
— addition of a new, normative Annex B for the internal inspection of translucent composite cylinders;
— information regarding intervals between periodic inspection and testing based on cylinder type, formerly listed in Tables 1 through 4, moved into new, informative Annex C;
— update of some photographs to provide sharper examples of damage.

This corrected version of ISO 11623:2015 incorporated the following correction.

In 12.5, paragraph 1, the word 'followed' has been replaced with 'preceded'.
