Bibliography

Provides a method for determining the noise emitted to the environment by earth-moving 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 specifies a method for determining the noise emitted to the environment by earth-moving machinery, measured in terms of the A-weighted sound power level while the machine is stationary and with the engine operating at the rated speed under no-load conditions.

It is applicable to earth-moving machinery as specified in AnnexA and as defined in ISO6165.
