21、elines for technical specificationsfor storage pumpsFOREWORD1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprisingall national electrotechnical committees (IEC National Committees). The object of the IEC is to promoteinternational co-operati
22、on on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with ma
23、yparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the International Organizationfor Standardization (ISO) in accordance with conditions determined by agree
24、ment between the twoorganizations.2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3) The docume
25、nts produced have the form of recommendations for international use and are published in the formof standards, technical reports or guides and they are accepted by the National Committees in that sense.4) In order to promote international unification, IEC National Committees undertake to apply IEC I
26、nternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5) The IEC provides no marking procedure to indicate its app
27、roval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subjectof patent rights. The IEC shall not be held responsible for identifying
28、 any or all such patent rights.The main task of IEC technical committees is to prepare International Standards. Inexceptional circumstances, a technical committee may propose the publication of a technicalreport of one of the following types: type 1, when the required support cannot be obtained for
29、the publication of an InternationalStandard, despite repeated efforts; type 2, when the subject is still under technical development or where for any other reasonthere is the future but no immediate possibility of an agreement on an InternationalStandard; type 3, when a technical committee has colle
30、cted data of a different kind from that which isnormally published as an International Standard, for example “state of the art“.Technical reports of types 1 and 2 are subject to review within three years of publication todecide whether they can be transformed into International Standards. Technical
31、reports oftype 3 do not necessarily have to be reviewed until the data they provide are considered to beno longer valid or useful.IEC 61366-7, which is a technical report of type 3, has been prepared by IEC technicalcommittee 4: Hydraulic turbines.Copyright International Electrotechnical Commission

46、ical specificationsfor storage pumps0 Introduction to technical specificationsThe main purpose of the technical specifications is to describe the specific technicalrequirements for the hydraulic machine for which the Tendering Documents (TD) are beingissued. To achieve clarity and to avoid confusion
47、 in contract administration, the Employershould not specify anything in the technical specifications, which is of importance only to thepreparation of the tender. Such information and instructions should be given only in theinstructions to Tenderers (ITT). Accordingly, the ITT may refer to other cha
48、pters and sectionsof the Tendering Documents but not vice versa. As a general rule the word “Tenderer“ shouldbe confined in use only to TD chapter 1 “Tendering requirements“ of the Tendering Document,elsewhere the term “Contractor“ should be used.Special attention should be given to items of a proje
49、ct specific nature such as materials,protective coating systems, mechanical piping systems, electrical systems, instrumentation. Itis common for Employers to use technical standards for such items which would apply to allcontracts for a particular project or projects. In this event, detailed technical standards shouldbe specified in TD chap
