EN 45510 is theresponsibility of JTFPE. The so called “common clauses”, as appropriate, also appear in italics in thedocuments specific to particular equipment.In this Guide, words in bold type indicate that they have the meaning given in the definitions, clause 3.In this Guide, words and sentences not in italics are specific to this Guide and refer to the particularequipment covered.SIST EN 45510-2-5:2003

Reference should be made to IEC 60034-17.The equipment covered by this Guide is defined by its function rather than design type.
Therefore, theguidance to the specification is stated in performance terms rather than being specified by a detaileddescription 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 equipment 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 theextent of supply for any given contract which is normally decided on the basis of the purchaser’s projectstrategy. 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 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 environmentalimplications of the equipment.2 Normative referencesThis Guide for Procurement incorporates by dated or undated reference, provisions from otherpublications.

In some cases specific requirements may be stated.For example: recording of the cumulative number of motor starts, incorporation of means to monitor motor circuits, (e.g. motor management schemes, protectionrelays with communications facility).8.2Components requiring periodic maintenanceThe specification should request the supplier to provide a schedule of components which requireperiodic maintenance or replacement. This should include the frequency of these operations. Thisschedule should include estimates of maintenance man-hours and cost of components. The suppliershould identify those maintenance replacement operations which require shut-down of the process morefrequently than the planned maintenance shut-downs.9Performance requirements9.1DutyThe specification should define the performance targets for the equipment at defined operating pointsand at other defined conditions. These may include efficiency and margins at full load operation andavailability.
