ADOPTED_FROM:ISO 7917:1987
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 brush saws for use primarily in forestry which are powered by internal combustion engines.
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 1); however, to simulate a normal operating situation of a brush saw, an absorbing ground is specified instead of a reflecting plane.
