18、 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. Internationa
19、l 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
20、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 lea
21、st 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 6
22、7, 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 revisio
23、n. ISO 15547 consists of the following parts, under the general title Petroleum, petrochemical and natural gas industries Plate-type heat exchangers: Part 1: Plate-and-frame heat exchangers Part 2: Brazed aluminium plate-fin heat exchangers API Standard 662 Part 1 / ISO 15547-1ivISO 15547-1:2005(E)
24、ISO 2005 All rights reserved vIntroduction 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 equipmen
25、t 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 req
26、uires 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, U
