This International Standard specifies a method for measuring the A-weighted and octave band sound pressure levels, at the operator's position, of noise emitted by portable, hand-held, combustion engine chain saws for use primarily in forestry.
The operating conditions during measurement simulate normal operating conditions in the forest.
NOTE — This International Standard is based on the general guidelines of ISO 6081; however, to simulate a normal operating situation of a chain saw an absorbing ground is specified instead of a reflecting plane.
