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.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards adopted

by the technical committees are circulated to the member bodies for voting. Publication as an International

Standard requires approval by at least 75 % of the member bodies casting a vote.

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.

ISO 10423 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.

This third edition cancels and replaces the second edition (ISO 10423:2001), of which it constitutes a minor

revision. Details of the differences between this third edition and the second edition may be obtained, upon

request, from ISO/TC 67/SC 4.

Introduction

This International Standard is based on API Spec 6A, seventeenth edition, February 1996, its errata and

supplement, and API Spec 6AV1, first edition, February 1996.

The contents of API Spec 14D (upon which ISO 10433 was based) and API Recommended Practice 14H (upon

which ISO 10419 was based) have been incorporated in API Spec 6A, seventeenth edition.

The International System of units (SI) is used in this International Standard. However, nominal sizes are shown as

fractions in the inch system.

The fractions and their decimal equivalents are equal and interchangeable. Metric conversions and inch

dimensions in this International Standard are based on the original fractional inch designs. Functional dimensions

have been converted into the metric system to ensure interchangeability of products manufactured in metric or inch

systems (see also Annex B).

Tables referenced in the main body of this International Standard which are marked with an asterisk are repeated

in Annex B in US Customary units with the same table number as in the main body but with the prefix B. In figures

where dimensions are only given in inches, the values of surface roughness have been indicated in accordance

with US draughting conventions. See also Annex M for listings of tables and figures.

Users of this International Standard should be aware that further or differing requirements may be needed for

individual applications. This International Standard is not intended to inhibit a vendor from offering, or the purchaser

from accepting, alternative equipment or engineering solutions for the individual application. This may be

particularly applicable where there is innovative or developing technology. Where an alternative is offered, the

vendor should identify any variations from this International Standard and provide details.
