This International Standard specifies a method for the measurement of the noise at the position of the operator(s) of a tractor or machine used in agriculture and forestry. The measured noise relates only to the basic machine and applies to self-propelled tractors and machines with either machine-carried or pedestrian operators. The results will provide information which will enable operators to avoid exposing themselves to noise levels which could put their hearing at risk.
The test procedures specified in this International Standard are survey methods as defined in ISO 2204.
This International Standard also specifies the general conditions for measuring and reporting the noise at an operator's position on agricultural and forestry tractors and field machines.
Additional conditions for measurements in connection with particular types of machines are specified in annexes as follows:
Annex A — Agricultural and forestry tractors
Annex В — Self-propelled agricultural machines
Annex C — Pedestrian-controlled agricultural machines
Annex D — Forestry forwarders and skidders
The conditions specified for the operation of the machines during the measurements are designed to provide a realistic and repeatable assessment of the maximum noise to which an operator should be subjected when operating a machine.
