22、l 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 es
23、tablished 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 standardi
24、zation. 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 vot
25、ing. 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 suc
26、h patent rights. ISO 10440-1 was prepared by Technical Committee ISO/TC 118, Compressors and pneumatic tools, machines and equipment, Subcommittee SC 1, Process compressors. This second edition cancels and replaces the first edition (ISO 10440-1:2000), which has been technically revised. ISO 10440 c
27、onsists of the following parts, under the general title Petroleum, petrochemical and natural gas industries Rotary-type positive-displacement compressors: Part 1: Process compressors Part 2: Packaged air compressors (oil-free) viii Introduction This part of ISO 10440 is based on API 619, 4th edition
28、, December 2004, with the intent that the 5th edition of API 619 will be identical to this part of ISO 10440. Users of this part of ISO 10440 should be aware that further or differing requirements may be needed for individual applications. This part of ISO 10440 is not intended to inhibit a vendor f
29、rom 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
30、part of ISO 10440 and provide details. A bullet () at the beginning of a subclause or paragraph indicates that either a decision is required or further information is to be provided by the purchaser. This information should be indicated on the datasheet(s), otherwise it should be stated in the quota
31、tion request or in the order. In this part of ISO 10440, where practical, US Customary (USC) units are included in brackets for information. Dedicated datasheets for SI units and for USC units are provided in Annex A. API Standard 619/ISO 10440-1:2007 1 Petroleum, petrochemical and natural gas indus
