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).

Introduction
In some circumstances, there may be a reason for seamless steel and seamless aluminium-alloy
cylinders designed, approved and used to standards or specifications recognized in a given jurisdiction
to be transferred for use in another jurisdiction (e.g. if a cylinder is no longer in service in the country of
origin due to low service pressure).
In some jurisdictions, a procedure called reassessment of conformity exists such as that given in
Directive 2010/35/EU on transportable pressure equipment (TPED) and Annex A of European
standards such as EN 1968.
The objective of this document is to verify whether a cylinder manufactured in accordance with
the specification of a given jurisdiction is acceptable for use in another country outside its original
jurisdiction. This is accomplished through either verification of original manufacturing certification
and information (when available) or through evaluation and testing of the cylinder in accordance with
given criteria to determine that the cylinder is safe to be used in the new (receiving) jurisdiction.
TECHNICAL SPECIFICATION ISO/TS 15453:2017(E)
Gas cylinders — Seamless steel and aluminium-alloy
gas cylinders — Evaluation of existing gas cylinders and
consideration of their safe use in other jurisdictions
1 Scope
This document details the checks, inspections and tests to be performed in order to qualify and certify
existing seamless steel and aluminium-alloy cylinders of water capacity less than 150 l used for the
transport of gases, manufactured in a jurisdiction in accordance with its national regulations, for use in
jurisdictions other than that of manufacture or first use.
NOTE For specific requirements regarding gas cylinders that have been used in toxic gas service, see 5.7.
This document does not address acetylene cylinders.

3.1
jurisdiction
country, region or group of countries or regions that have the same regulations for gas cylinders
3.2
manufacturing certificate
certificate of initial inspection and testing issued by an authorized body confirming that the cylinder
complies with the applicable standards or specification at time of manufacture
3.3
owner
individual who, or organization that, owns the cylinder
3.4
group of cylinders
cylinders made of the same materials (steel or aluminium-alloy) defined by the production dates for a
given period, during which the provisions of the applicable standards or specifications accepted by the
competent authority have not changed in their technical content
3.5
batch
a number of cylinders from the same group of cylinders (3.4) that have similar characteristics such as
same manufacturer, working pressure (3.6) and design standard
Note 1 to entry: For the purposes of this document, the term “batch” is not the same as a manufacturing batch.
3.6
working pressure
settled pressure of a compressed gas at a uniform reference temperature of 15 °C in a full gas cylinder
Note 1 to entry: In North America service pressure is often used to indicate a similar condition, usually at 21,1 °C
(70 °F).
