Description / Abstract:
This International Standard describes a method for determining at the
operator's position the noise
emitted by earth-moving machinery, in terms of the equivalent
continuous A-weighted sound pressure
level, while the machine is operating under dynamic test conditions.
This International Standard is applicable to the following specific
crawler and wheeled types of
earth-moving machinery:
- excavators (hydraulic or rope-operated) (see figure 1),
- tractors with dozer equipment (see figure 2),
- loaders (see figure 3), and
- backhoe loaders (also known as excavator-loaders) (see figure 4).
