Foreword
GB/T 10069 “Measurement of the airborne noise emitted by rotating electrical
machines and the noise limits” is currently composed the following two parts.
- Part 1. Measurement of the 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;
- Part 2. Measurement of the airborne noise emitted by rotating electrical
machines and the noise limits - Part 2. Noise limit.
This part is part 1, which replaces GB/T 10069.1-1988 “Engineering method for
the measurement of airborne noise” AND GB/T 10069.2-1988 “Survey method
for the measurement of airborne noise” from the date of implementation. This
part, through modification, adopts the ISO 1680.1999 “Acoustics - Test code
for the measurement of airborne noise emitted by rotating electrical machines”.
The contents are basically consistent. BUT in this part, it adds only the
appendix on the provisions for simplifying measuring points in the context of an
approximate free field and the appendix of testing the load noise with vibration
speed method.
Appendix A ~ Appendix D are normative.
This part was proposed by AND shall be under the jurisdiction of the National
Standardization Technical Committee on Rotary Motor (SAC/TC 26).

This Standard replaces the standard previously issued as follows.
- GB/T 2806-1981;
- GB/T 10069.1-1988, GB/T 10069.2-1988.
Measurement of the 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 required for the test.
Noise emission characteristics include the sound power level and the 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 standard as a noise test standard ensures the reproducibility of
the determination of the noise emission characteristics within specified limits
determined by the level of accuracy of the basic noise measurement method
used. Noise measurement methods allowed by this standard are precision
method (level 1), engineering method (level 2), and survey method (level 3).
Method of engineering level (level 2) are to be preferred.
This part is applicable to rotating electrical machines of any length, width, or
height.
