GB/T 10069.1-2006 Measurement of airborne noise emitted by rotating electrical machines and the noise limits Part 1: Method for the measurement of airborne noise emitted by rotating electrical machines (English Version)
Measurement of airborne noise emitted by rotating electrical machines and the noise limits Part 1: Method for the measurement of airborne noise emitted by rotating electrical machines
1 Scope
This part 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 that shall be used 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 part may ensure same precision grade as the determination of the noise emission characteristics with the basic noise measurement method used. Noise measurement methods allowed by this part are laboratory methods (grade 1), engineering methods (grade 2) and survey methods (grade 3). Methods of engineering grade (grade 2) are to be preferred.
This part is applicable to rotating electrical machines of any length, width or height.
