Applies to laboratory models of any type of impulse or reaction hydraulic turbine, storage pump or pump-turbine.

IEC 60193:1999 applies to laboratory models of any type of impulse or reaction hydraulic turbine, storage pump or pump-turbine. This standard applies to models of prototype machines either with unit power greater than 5 MW or with reference diameter greater than 3 m. Full application of the procedures herein prescribed is not 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 operating as a pump. This standard excludes all matters of purely commercial interest, except those inextricably bound up with the conduct of the tests. This standard is concerned with neither the structural details of the machines nor the mechanical properties of their components, so long as these do not affect model performance or the relationship between model and prototype performances.
The main objectives of this standard are:
– to define the terms and quantities used;
– to specify methods of testing and of measuring the quantities involved, in order to ascertain the 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, have been fulfilled;
– to define the extent, content and structure of the final report.
The guarantees can be given in one of the following ways:
– guarantees for prototype hydraulic performance, computed from model test results considering scale effects;
– guarantees for model hydraulic performance.
