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 15547-1 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 first edition of ISO 15547-1, together with ISO 15547-2, cancels and replaces ISO 15547:2000, of which

it constitutes a technical revision.

ISO 15547 consists of the following parts, under the general title Petroleum, petrochemical and natural gas

industries — Plate-type heat exchangers:

Introduction

Users of this part of ISO 15547 should be aware that further or differing requirements may be needed for

individual applications. This part of ISO 15547 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 part of ISO 15547 and provide details.

This part of ISO 15547 requires the purchaser to specify certain details and features.

A bullet (z) at the beginning of a clause or subclause indicates a requirement for the purchaser to make a

decision or provide information (for information, a checklist is provided in Annex B).

In this part of ISO 15547, where practical, US Customary units are included in parentheses for information.
