Description / Abstract:
This International Standard specifies all the information
necessary to carry out efficiently and under standardized
conditions the determination, declaration, and verification of the
noise emission characteristics of rotating electrical machines. It
specifies noise measurement methods that can be used, and specifies
the operating and mounting conditions required for the test.
Noise emission characteristics include the sound power level and
emission sound pressure level. The determination of these
quantities is necessary:
- for comparing the noise emitted by machines;
- to enable manufacturers to declare the noise emitted; and
- for the purposes of noise control.
The use of this International Standard as a noise test code
ensures the reproducibility of the determination of the noise
emission characteristics within specified limits determined by the
grade of accuracy of the basic noise measurement method used. Noise
measurement methods allowed by this International Standard are
precision methods (grade 1), engineering methods (grade 2) and
survey methods (grade 3). Methods of engineering grade (grade 2)
are to be preferred.
This International Standard is applicable to rotating electrical
machines of any length, width or height.
