ISO 7216:2015

ISO 7216:2015 specifies a method for measuring the A-weighted sound pressure level of the noise emitted by agricultural and forestry tractors while the vehicle is in motion.
The conditions specified for the operation of the agricultural and forestry tractors during the measurements are defined to provide a realistic and repeatable assessment of the maximum noise emitted when it is in motion.
ISO 7216:2015 is applicable to agricultural and forestry tractors, fitted with elastic tyres or rubber tracks.
It is not applicable to special forestry machinery, for example, forwarders, skidders, etc., as defined in ISO 6814 and agricultural and forestry tractors, fitted with steel tracks.
NOTE          The test method calls for an acoustical environment which can only be obtained in an extensive open space.
