This edition incorporates technical changes which have been introdu
10、ced into related ISO Standards and other documents which are under consideration by the responsible technical committee. Other changes include (a)updating of reference documents; (b)adoption of the terms clearing saw, brushcutter and grass trimmer to describe the styles of units covered by this Stan
11、dard; and (c)editorial changes in accordance with Standards Australia policy. This Standard does not give recommendations for the safe use of clearing saws, brushcutters and grass trimmers. Guidance for safe working is covered in AS 3576, BrushcuttersGuide to safe working practices. This Standard do
12、es not prescribe specific methods for the measurement of sound power levels for the purpose of hearing conservation programs. Reference should be made to AS 3534, AcousticsMethod for measurement of airborne noise emitted by powered lawn mowers, edge and brushcutters, and string trimmers. Duringthede
