Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISOmember bodies). The work of preparing International Standards is normally carried out through ISO technicalcommittees. Each member body interested in a subject for which a technical committee has been established hasthe right to be represented on that committee. International organizations, governmental and non-governmental, inliaison with ISO, also take part in the work. ISO collaborates closely with the International ElectrotechnicalCommission (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 ofpatent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 10440-1 was prepared by Technical Committee ISO/TC 118, Compressors, pneumatictools and pneumatic machines, and Technical Commitee ISO/TC 67, Materials, equipment and offshore structuresfor petroleum and natural gas industries, Subcommittee SC 6, Processing equipment and systems.
ISO 10440 consists of the following parts, under the general title Petroleum and natural gas industries — Rotary-type positive-displacement compressors:
� Part 1: Process compressors (oil-free)
� Part 2: Packaged air compressors (oil-free)
Annex A forms a normative part of this part of ISO 10440.

Introduction
This part of ISO 10440 is based on the 2nd edition of API 619. This part of ISO 10440 is not intended to obviate theneed for sound engineering judgement as to when and where this standard should be utilized, and users should beaware that further or differing requirements may be needed for individual applications.
This part of ISO 10440 is not intended to inhibit a vendor from offering, or the purchaser from accepting, alternativeequipment or engineering solutions for the individual application. This may be particularly applicable where there isinnovative or developing technology. Where an alternative is offered, the vendor should identify any variations fromthis part of ISO 10440 and provide details.
Standards referenced herein may be replaced by other international or national standards that can be shown tomeet or exceed the requirements of the referenced standards.

Part 1:Process compressors (oil-free)
1 Scope
This part of ISO 10440 specifies requirements and gives recommendations for helical, spiral and straight loberotary compressors used for vacuum or pressure, or both, for use in the petroleum and natural gas industries. Thispart of ISO 10440 is applicable to compressors that are in continuous duty and are unspared. This part ofISO 10440 does not apply to standard air compressors, liquid ring compressors, vane-type compressors, orcompressors in oxygen-bearing gas service using flammable liquid for injection or flooding.
NOTE A bullet (�) at the beginning of a paragraph indicates that either a decision is required or further information is to beprovided by the purchaser. This information should be indicated on the data sheets (see annex A), otherwise it should be statedin the quotation request or in the order.
