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.

For an explanation of 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

www.iso.org/iso/foreword.html.

This document was prepared by Technical Committee ISO/TC 67 Materials, equipment and offshore

structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 4 Drilling and

production equipment, in collaboration with the European Committee for Standardization (CEN)

Technical Committee CEN/TC 12, Materials, equipment and offshore structures for petroleum,

petrochemical and natural gas industries, in accordance with the Agreement on technical cooperation

between ISO and CEN (Vienna Agreement).

This fifth edition cancels and replaces the fourth edition (ISO 10423:2009), which has been technically

revised.
This document supplements API Spec 6A, 21 edition (2018).

The technical requirements of this document and API Spec 6A used to be identical. In the meantime

API Spec 6A has been technically revised as API Spec 6A, 21 edition (2018). The purpose of this edition

of ISO 10423 is to bring it up to date, by referencing the current edition of API Spec 6A and including

supplementary content.
The main change are as follows:
— full reorganization of the document;
— supplementary requirements for closure bolting, fittings and pressure b
