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 3.

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 International Standard may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

International Standard ISO 15547 was prepared by Technical Committee ISO/TC 67, Materials, equipment and

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

systems.

Introduction
This International Standard is based on API standard 662, December 1995 edition.

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 an 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 round bullet (�) 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 should be indicated on the plate heat exchanger

checklist (see annex B).

A triangular bullet (▲) at the beginning of a clause or subclause indicates an item appearing on the plate heat

exchanger data sheet (see annex C).
