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.

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 International Standard may be the subject of

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

ISO 10442 was prepared by Technical Committee ISO/TC 118, Compressors, pneumatic tools and pneumatic

machines, in collaboration with Technical Committee ISO/TC 67, Materials, equipment and offshore structures for

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

Annex D forms a normative part of this International Standard. Annexes A, B and C are for information only.

Introduction

This International Standard is based on the American Petroleum Institute's API Std 672, second edition, April 1988.

Some of the content of this International Standard is identical or similar to ISO 10439, which covers centrifugal

compressors for the petroleum, chemical and gas service industries.

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.

1 Scope

This International Standard specifies requirements and gives recommendations for the design, materials,

fabrication, inspection, testing and preparation for shipment of constant-speed, packaged, integrally geared

centrifugal air compressors, including their accessories, for use in the petroleum, chemical and gas service

industries. It is also applicable to gas services other than air that are non-hazardous and non-toxic. It is not

applicable to machines that develop a pressure rise of less than 35 kPa above atmospheric pressure, which are

classed as fans or blowers.

NOTE In this International Standard, where practical, US customary units have been included in brackets for information.

2 Normative references

The following normative documents contain provisions which, through reference in this text, constitute provisions of

this International Standard. For dated references, subsequent amendments to, or revisions of, any of these

publications do not apply. However, parties to agreements based on this International Standard are encouraged to

investigate the possibility of applying the most recent editions of the normative documents indicated below. For

undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC

maintain registers of currently valid International Standards.
