25、of JTFPE. The so called “common clauses”, as appropriate, also appear in italics in the documents specific to particular equipment. In this Guide, words in bold type indicate that they have the meaning given in the definitions, clause 3. Where paragraphs of “common claues” are omitted, each paragrap

35、 Functional and performance tests 15 Annex A (informative) Bibliography 16Page 4 EN 45510-6-1:1998 BSI 1998 1 Scope This standard gives guidance on writing the technical specification for the procurement of deaerators associated with steam generating plant and steam turbine plant for use in electric
36、ity 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 equipment have not been considered in the preparation of this Guide. This Guide covers all type
37、s of deaerators installed in power plants whose function is to accept condensate from the LP (low pressure) feed train, to heat and deaerate the water to a specified level and then supply it as feed to the feed pumps. The feedwater storage tank provides a reservoir of deaerated feedwater to satisfy
38、system transient and feed pump suction requirements. It also acts as a receiving vessel for HP (high pressure) heater drains and feed pump recirculation flows. The term deaerator in this context is taken to include the deaerating tower or dome, the feedwater storage tank and associated plant. The eq
39、uipment 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 specified by a detailed description of the equipment to be supplied. This Guide indicates to potential purchasers how their
40、specification should be prepared so that: the equipment type and capacity interfaces correctly with other elements of the systems; predicted performance is achieved; ancillary equipment is properly sized; reliability, availability and safety requirements are achieved; proper consideration is given t
41、o 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 of supply for any given contract which is normally decided on the basis of the purchasers project strategy. It does not cove
42、r: 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 Guide does not prescribe the arrangement of the documents in the enquiry. NOTE As a comprehensive European environmental po
43、licy is still under preparation, this Guide does not address the environmental implications of the equipment. 2 Normative references This Guide for procurement incorporates by dated or undated reference, provisions from other publications. These normative references are cited in the appropriate plac
