Safety requirements for electrical equipment for measurement, control, and laboratory use - Part 3-0...
A technical report for use by test houses and other users. It assists them with determining and recording verification of conformity of the equipment under test with the requirements of IEC 61010-2-031 (1994). If the paper version of the report is ordered, a diskette is provided with fill-in tables for recording the test results. If the report is downloaded directly from the web, it consists of…
Hydraulic turbines, storage pumps and pump-turbines - Model acceptance tests
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.…
