36、es, including gas turbines for combined-cycle systems, and their auxiliaries for use in electricity generating stations (power stations). This Guide for procurement is not applicable to equipment for use in the nuclear reactor plant area of nuclear power stations. Other possible applications of such
37、 equipment have not been considered in the preparation of this Guide. This Guide is applicable to open-cycle gas turbines using normal combustion systems, generally greater than 20 MW electrical output, and also includes closed-cycle, semi closed-cycle and combined-cycle gas turbine power plants and
38、 combined heat and power plants. In cases of turbines using free piston gas generators or special heat sources (for example, chemical process, nuclear reactors, furnace for a super-charged boiler), this Guide may be used as a basis but will need to be suitably modified. This Guide excludes gas turbi
39、nes for marine propulsion and those used to propel aircraft, locomotives, military vehicles, road construction and earth-moving machines, agricultural and industrial types of tractors and road vehicles. This Guide for procurement of gas turbines has been prepared to be used with the existing interna
40、tional standard ISO 3977. It should, therefore, be read in addition and complementary to the international standard. The equipment covered by this Guide is defined by its function rather than design type. Therefore, the guidance to the specification is stated in performance terms rather than being s
41、pecified by a detailed description of the equipment to be supplied. This Guide indicates to potential purchasers how their specification should be prepared so that: the equipment type and capacity interfaces correctly with other elements of the systems; predicted performance is achieved; ancillary e
42、quipment is properly sized; reliability, availability and safety requirements are achieved; proper consideration is given to the evaluation process and the quality measures to be applied. This Guide does not determine the type of specification (e.g. detailed, performance, functional) or the extent o
43、f supply for any given contract which is normally decided on the basis of the purchasers project strategy. It does not cover: any commercial, contractual or legal issues which are normally in separate parts of an enquiry; any allocation of responsibilities which are determined by the contract. This
44、Guide does not prescribe the arrangement of the documents in the enquiry. NOTE As a comprehensive European environmental policy is still under preparation, this Guide does not address the environmental implications of the equipment. 2 Normative references This Guide for procurement incorporates by d
45、ated or undated reference, provisions from other publications. These normative references are cited in the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this Guide only when
