This International Standard specifies a method for determining the exterior noise emitted by earth-moving machinery in terms of the A-weighted sound power level while the machine is stationary with the engine operating at rated speed under no-load conditions.
This International Standard is applicable to the following specific types of earth-moving machinery:
— excavators (hydraulic or rope-operated);
— crawler and wheel tractor-dozers;
— crawler and wheel loaders; and
— backhoe loaders.
