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

Introduction

The objective of this document is to ensure that pipework, pipelines, tanks and vessels repaired using

composite systems that are qualified, designed, installed and inspected using this document will meet

the specified performance requirements. Repair systems are designed for use within the petroleum,

petrochemical and natural gas industries, and also within utility service applications. The main users

of this document will be plant and equipment owners of the pipework and vessels, design contractors,

suppliers contracted to provide the repair system, certifying authorities, installation, maintenance and

inspection contractors.

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.

Introduction

The objective of this document is to ensure that pipework, pipelines, tanks and vessels repaired using

composite systems that are qualified, designed, installed and inspected using this document will meet

the specified performance requirements. Repair systems are designed for use within the petroleum,

petrochemical and natural gas industries, and also within utility service applications. The main users

of this document will be plant and equipment owners of the pipework and vessels, design contractors,

suppliers contracted to provide the repair system, certifying authorities, installation, maintenance and

inspection contractors.
