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 Technical Committee ISO/TC 67, Materials, equipment and offshore
structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 2, Pipeline
transportation systems.
This second edition partly cancels and replaces the first edition (ISO 12736:2014), which has been
technically revised and split into three parts.
The main changes compared to the previous edition are as follows:
— clearer delineation between validation and projects;
— introduction of material classes;
— modification of material property testing requirements, including detailed thermal conductivity
testing requirements;
— introduction of additional long-term testing requirements;
— introduction of additional system testing requirements, including system interfaces;
— removal of project specific testing requirements;
— addition of requirement for risk-based analysis of the system long-term performance;
— modifications of the format and content requirements of the final validation dossier;
— addition of informative annex with guidelines for using this document.
