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 10437 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures

for petroleum, petrochemical and natural gas industries, Subcommittee SC 6, Processing equipment and

systems.

This second edition cancels and replaces the first edition (ISO 10437:1993), which has been technically

revised.

Introduction
This International Standard is based on API Std 612, fourth edition, June 1995.

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 appropriate 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.

This International Standard requires the purchaser to specify certain details and features.

A bullet (z) at the beginning of a clause or subclause indicates that either a decision is required or further

information is to be provided by the purchaser. This information or decision should be indicated on the data

sheets; otherwise it should be stated in the quotation request (inquiry) or in the order.

In this International Standard, where practical, US Customary units have been included in brackets for

information.
