Description / Abstract:
This International Standard specifies a method for measuring the
A-weighted sound pressure level of
the noise emitted by agricultural and forestry wheeled tractors and
self-propelled machines, fitted
with elastic tyres, the noise being measured while the vehicle is in
motion.
It is not applicable to special forestry machinery, for example,
forwarders, skidders, etc., as
deftned in ISO 6814.
NOTE 1 The test method calls for an acoustical environment which can
only be obtained in an
extensive open space.
