14、er 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, government
15、al 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 Direct
16、ives, 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 bodie
17、s 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 3977-3 was prepared by Technical Committee ISO/TC 192, Gas turbines. This secon
18、d edition cancels and replaces the first edition (ISO 3977-3:2002), of which it constitutes a technical revision. ISO 3977 consists of the following parts, under the general title Gas turbines Procurement: Part 1: General introduction and definitions Part 2: Standard reference conditions and ratings

20、ONAL STANDARD ISO 3977-3:2004(E) ISO 2004 All rights reserved 1Gas turbines Procurement Part 3: Design requirements 1 Scope This part of ISO 3977 covers the design requirements for the procurement of all applications of gas turbines and gas turbine systems, including gas turbines for combined cycle
21、systems and their auxiliaries, by a purchaser from a packager. It also provides assistance and technical information to be used in the procurement. It is not intended to deal with local or national legislative requirements with which the installation may be required to conform. This part of ISO 3977
22、 is applicable to simple-cycle, combined-cycle and regenerative-cycle gas turbines working in open systems. It is not applicable to gas turbines used to propel aircraft, road construction and earth moving machines, agricultural and industrial types of tractors and road vehicles. In cases of gas turb
23、ines using special heat sources (for example, chemical process, nuclear reactors, furnace for a super-charged boiler), this part of ISO 3977 provides a basis. The relevant parts of ISO 3977 are applicable to closed and semi-closed systems. NOTE Additional requirements for special gas turbine applica
24、tions are described in ISO 3977-5. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments)
25、applies. NOTE In cases where there are no International Standards available, national standards as shown in Annex B may be used as guidelines with the mutual agreement of the purchaser and packager.
