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.

This document was prepared by ISO/TC 58, Gas cylinders, Subcommittee SC 4, Operational requirements

for gas cylinders.

This first edition cancels and replaces ISO 6406:2005 and ISO 10461:2005, which have been technically

revised. It also incorporates the Amendment ISO 10461:2005/Amd 1:2006.
The main changes are:
— a section has been added for symbols used in the document;

— a detailed account of steps to be taken if the actual cylinder wall thickness is less than the minimum

design wall thickness has been added;

— a clearer way to ultrasonically test cylinders with a built-in footring, especially for seamless steel

cylinders with a convex base, has been added;

— improved guidelines have been added for dealing with the effects of heating of seamless aluminium-

alloy cylinders.

Introduction

This document provides information and procedures for the periodic inspection and testing of seamless

steel and seamless aluminium-alloy cylinders and the condition of the test equipment. The principal

aim of periodic inspection and testing is that at the completion of the test the cylinders have been

requalified and are suitable to be reintroduced into service for a further period of time.

This document requires that well-trained and competent personnel undertake the work as described

in this document, who consult the cylinder’s manufacturer if there are doubts about aspects of the

document, so that the cylinder manufacturer's current recommendations are taken into account.

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

This document was prepared by ISO/TC 58, Gas cylinders, Subcommittee SC 4, Operational requirements

for gas cylinders.

This first edition cancels and replaces ISO 6406:2005 and ISO 10461:2005, which have been technically

revised. It also incorporates the Amendment ISO 10461:2005/Amd 1:2006.
The main changes are:
— a section has been added for symbols used in the document;

— a detailed account of steps to be taken if the actual cylinder wall thickness is less than the minimum

design wall thickness has been added;

— a clearer way to ultrasonically test cylinders with a built-in footring, especially for seamless steel

cylinders with a convex base, has been added;

— improved guidelines have been added for dealing with the effects of heating of seamless aluminium-

alloy cylinders.

Introduction

This document provides information and procedures for the periodic inspection and testing of seamless

steel and seamless aluminium-alloy cylinders and the condition of the test equipment. The principal

aim of periodic inspection and testing is that at the completion of the test the cylinders have been

requalified and are suitable to be reintroduced into service for a further period of time.

This document requires that well-trained and competent personnel undertake the work as described

in this document, who consult the cylinder’s manufacturer if there are doubts about aspects of the

document, so that the cylinder manufacturer's current recommendations are taken into account.

[23]

This document has been written so that it is suitable to be referenced in the UN Model Regulations .

1 Scope

This document specifies the requirements for periodic inspection and testing to verify the integrity of

cylinders and tubes to be re-introduced into service for a further period of time.

This document is applicable to seamless steel and seamless aluminium-alloy transportable gas cylinders

(single or those that comprise a bundle) intended for compressed and liquefied gases under pressure, of

water capacity from 0,5 l up to 150 l and to seamless steel and seamless aluminium-alloy transportable

gas tubes (single or those that comprise a bundle) intended for compressed and liquefied gases under

pressure, of water capacity greater than 150 l. It also applies, as far as practical, to cylinders of less than

0,5 l water capacity.

This document does not apply to the periodic inspection and maintenance of acetylene cylinders or to

the periodic inspection and testing of composite cylinders.

Vorwort

ISO (die Internationale Organisation für Normung) ist eine weltweite Vereinigung nationaler

Normungsorganisationen (ISO-Mitgliedsorganisationen). Die Erstellung von Internationalen Normen wird

üblicherweise von Technischen Komitees von ISO durchgeführt. Jede Mitgliedsorganisation, die Interesse an

einem Thema hat, für welches ein Technisches Komitee gegründet wurde, hat das Recht, in diesem Komitee

vertreten zu sein. Internationale staatliche und nichtstaatliche Organisationen, die in engem Kontakt mit ISO

stehen, nehmen ebenfalls an der Arbeit teil. ISO arbeitet bei allen elektrotechnischen Themen eng mit der

Internationalen Elektrotechnischen Kommission (IEC) zusammen.

Die Verfahren, die bei der Entwicklung dieses Dokuments angewendet wurden und die für die weitere Pflege

vorgesehen sind, werden in den ISO/IEC-Direktiven, Teil 1 beschrieben. Es sollten insbesondere die

unterschiedlichen Annahmekriterien für die verschiedenen ISO-Dokumentenarten beachtet werden. Dieses

Dokument wurde nach den Gestaltungsregeln der ISO/IEC-Direktiven, Teil 2 erarbeitet (siehe

www.iso.org/directives).

Es wird auf die Möglichkeit hingewiesen, dass einige Elemente dieses Dokuments Patentrechte berühren

können. ISO ist nicht dafür verantwortlich, einige oder alle diesbezüglichen Patentrechte zu identifizieren.

Details zu allen während der Entwicklung des Dokuments identifizierten Patentrechten finden sich in der

Einleitung und/oder in der ISO-Liste der erhaltenen Patenterklärungen (siehe www.iso.org/patents).

Jeder in diesem Dokument verwendete Handelsname dient nur zur Unterrichtung der Anwender und

bedeutet keine Anerkennung.

Eine Erläuterung zum freiwilligen Charakter von Normen, der Bedeutung ISO-spezifischer Begriffe und

Ausdrücke in Bezug auf Konformitätsbewertungen sowie Informationen darüber, wie ISO die Grundsätze der

Welthandelsorganisation (WTO) hinsichtlich technischer Handelshemmnisse (TBT) berücksichtigt, enthält
