Sets out methods for the measurement, at the operator's position and at specified positions of bystanders for the purpose of hearing conservation, of the sound emitted under normal operating conditions of counterbalanced and non-counterbalanced, sit-drive and pedestrian controlled lift-trucks, as defined in AS 1763 and AS 2359.1.

This Standard sets out methods for the measurement, at the operator's position and at specified positions of bystanders for the purpose of hearing conservation, of the sound emitted under normal operating conditions of counterbalanced and non-counterbalanced, sit-drive and pedestrian controlled lift-trucks, as defined in AS 1763 and AS 2359.1.NOTES:1. This Standard is not to be used for assessment of annoyance.2. For additional information on Hearing Conservation see AS 1269.
