This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 2000, and conflicting national standards shall be withdrawn at the latest by April 2000. According to t
23、he CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Noway, Portugal, Spain, S

35、 LibT 9 Page 6 EN 4551 0-6-411 999 1 Scope This standard gives guidance on writing the technical specification for the procurement of the pump units for use in electricity generating stations (power stations). This Guide for procurement is not applicable to equipment for use in the nuclear reactor p
36、lant area of nuclear power stations. Other possible applications of such equipment have not been considered in the preparation of this Guide. This Guide covers: - feedwater pumps (including the start-up and booster pumps); - condensate pumps and condensate booster pumps; - condenser cooling water pu
37、mps; - boiler recirculation pumps; - heater drains pumps; - water recirculation pumps of the different systems: feedwater storage tank, exhaust gas coolers, etc.; - auxiliary service water pumps; - flue gas desulphurization (Des - supports of the pump(s) and of the drive and ancillary systems (filte
38、rs, coolers, lubrication system); - maintenance tools; - couplings; - all the services which enable a complete installation of a pump unit. the motor), the turning gear; This Guide does not cover the drive machine itself (turbine, electrical motor, combustion engine). The equipment covered by this G
39、uide 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 Specification should be p
40、repared 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 to the evaluation
41、 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 cover: - any commerc
42、ial, contractual or legal issues which are normally in separate pars 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. QBSI 01-2000 Page 7 EN 4551 0-6-411 999 NOTE: As a comprehensi
43、ve 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 dated or undated reference, provisions from other publications.
