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 electrical requirements applicable to electrically driven machines, reference should be made to IEC 60335-1 . NOTE — For motion control requirements related to self-propelled machines, reference should be made to ISO 5395. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard.
