Description

This International Standard specifies mechanical safety requirements and test methods applicable to walk-behind

powered edgers that employ rigid cutting means with a blade tip circle not more than 305 mm in diameter, and

where the plane of the blade tip circle is designed to operate at not more than 15° from the vertical.

This International Standard applies to hand-held portable and powered edgers employing a rigid cutting element

with a blade tip circle not more than 305 mm in diameter.

This International Standard also includes test methods for noise and vibration.

This International Standard does not cover edgers with cutting means of non-metallic filament line or freely pivoting

non-metallic cutters.

This International Standard does not cover accessories or attachments that alter the function of the machine.

The electrical aspects of electrically powered edgers are not covered by this International Standard. For the
