CEN/TC 197/SC 3 - Testing of pumps

This standard deals with hydrolic performance tests for acceptance of rotodynamic pumps.

This standard describes the hydrostatic test to be applied, to internal pressure containing parts of all liquid pumps, including any auxiliary equipment making up a pump unit as described in the scope of prEN 809, except: domestic pumps of a power less than 200 W (EN 60335-2-51), circulation pumps (EN 1151) and electric pumps (EN 60335-2-41).

This European Standard specifies all the information necessary to carry out efficiently and under standardized conditions the determination, declaration and verification of the airborne noise emission of liquid pumps or pump units (see 4.1). It specifies the noise measurement methods and the operating and mounting conditions that shall be used for the test. Noise emission characteristics include emission sound pressure levels at specified positions and the sound power level.
