32、 to laboratory models of any type of impulse or reactionhydraulic turbine, storage pump or pump-turbine.This standard applies to models of prototype machines either with unit power greater than5 MW or with reference diameter greater than 3 m. Full application of the procedures hereinprescribed is no
33、t generally justified for machines with smaller power and size. Nevertheless,this standard may be used for such machines by agreement between purchaser and supplier.In this standard, the term “turbine“ includes a pump-turbine operating as a turbine and the term“pump“ includes a pump-turbine operatin
34、g as a pump.This standard excludes all matters of purely commercial interest, except those inextricablybound up with the conduct of the tests.This standard is concerned with neither the structural details of the machines nor themechanical properties of their components, so long as these do not affec
35、t model performanceor the relationship between model and prototype performances.1.1.2 ObjectThis International Standard covers the arrangements for model acceptance tests to beperformed on hydraulic turbines, storage pumps and pump-turbines to determine if the mainhydraulic performance contract guar
36、antees (see 1.4.2) have been satisfied.It contains the rules governing test conduct and prescribes measures to be taken if any phaseof the tests is disputed.The main objectives of this standard are: to define the terms and quantities used; to specify methods of testing and of measuring the quantitie
37、s involved, in order to ascertainthe hydraulic performance of the model; to specify the methods of computation of results and of comparison with guarantees; to determine if the contract guarantees, which fall within the scope of this standard, havebeen fulfilled; to define the extent, content and st
38、ructure of the final report.The guarantees can be given in one of the following ways: guarantees for prototype hydraulic performance, computed from model test resultsconsidering scale effects; guarantees for model hydraulic performance.EN 60193:1999 7 Licensed Copy: Wang Bin, na, Wed Jul 19 07:55:11
39、 BST 2006, Uncontrolled Copy, (c) BSIMoreover additional performance data (see 1.4.4) can be needed for the design or theoperation of the prototype of the hydraulic machine. Contrary to the requirements of clauses 1to 3 related to main hydraulic performance the information of these additional data g
40、iven inclause 4 is considered only as recommendation or guidance to the user (see 4.1).It is particularly recommended that model acceptance tests be performed if the expected fieldconditions for acceptance tests (see IEC 60041) would not allow the verification of guaranteesgiven for the prototype ma
41、chine.This standard may also be applied to model tests for other purposes, i.e. comparative tests andresearch and development work.If model acceptance tests have been performed, field tests can be limited to index tests (seeIEC 60041, clause 15).If a contradiction is found between this standard and
42、any other standard, this standard shallprevail.1.2 Normative referencesThe following normative documents contain provisions which, through reference in this text,constitute provisions of this International Standard.
