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.

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.
