scope:

This International Standard specifies safety requirements and their verification for the design and construction of portable, hand-held, internal combustion engine driven, cut-off machines, intended to be used by a single operator in the cutting of construction materials, such as asphalt, concrete, stone and metal. It is applicable to those machines designed purposely for use with a rotating, bonded-abrasive and/or super-abrasive (diamond) cut-off wheel having a maximum outer diameter of 406 mm, centre-mounted on, and driven by, a spindle shaft, where the top of the wheel rotates away from the operator (see Figure 1). It deals with all hazards, hazardous situations and events significant to these machines when they are used as intended and under condition of reasonable foreseeable misuse. NOTE See Annex F for list of significant hazards. It specifies methods for the elimination or reduction of hazards arising from their use, as well as the type of information on safe working practices to be provided with the machines. Cut-off machines designed in accordance with this International Standard are intended to be used by persons who have read and understood the safety requirements given in the "instruction handbook" and who use the appropriate personal protective equipment (PPE). This International Standard is not applicable to machines manufactured before the date of its publication.
