AS ISO 6393:2019 PDF
The objective of this Standard is to specify a method for determining the noise emitted to the environment by earthmoving machinery, measured in terms of the A-weighted sound power level while the machine is stationary with the engine operating at the rated speed under no-load conditions.
This International Standard is a specific test code for earth-moving machinery as defined in ISO 6165. Specific procedures are described in this International Standard to enable the sound power emission in stationary test conditions to be determined in a manner which is repeatable. Attachments (bucket, dozer, etc.) for the manufacturer’s production version are intended to be fitted since this is the configuration most likely to exist when the machine is in actual use.
This International Standard enables compliance with noise limits to be determined. It can also be used for evaluation purposes in noise reduction investigations.
A complementary test code is given in ISO 6394. This other specific test code is intended to be used to determine the noise emitted by earth-moving machinery, measured at the operator’s position in terms of the A-weighted sound pressure level, with the machine under stationary test conditions.
Corresponding measurements of noise emitted to the environment and noise at the operator’s position under dynamic test conditions are described in ISO 6395 and ISO 6396 respectively
