ISO 19432-1-2020 pdf free.Building construction machinery andequipment—Portable, hand-held,internal combustion engine-drivenabrasive cutting machines.
This document specifies safety requirements and measures for their verification for the design andconstruction of portable, hand-held, internal combustion engine-driven cut-off machines intended tobe used by a single operator in the cutting of construction materials, such as asphalt, concrete, stoneand metal. lt is applicable only to those machines designed purposely for use with a rotating, bondedabrasive and/or super-abrasive (for example diamond) cut-off wheel having a maximum outer diameterof 430 mm, centre-mounted on and driven by a spindle shaft where the top of the wheel rotates awayfrom the operator (see Figure 1).
This document deals with all significant hazards, hazardous situations or hazardous events significantto these machines when they are used as intended and under conditions of misuse which are reasonablyforeseeable by the manufacturer. See Annex F for a list of significant hazards.
This document specifies methods for the elimination or reduction of hazards arising from their use, aswell as the type of information on safe working practices to be provided with the machines.
Cut-off wheel specifications are not considered in this document.Cut-off wheels are deemed to complyto existing cut-off wheel standards.
NOTEFor example see Bibliography.
All through the document, portable, hand-held, internal combustion engine-driven cut-off machines arecalled “cut-off machines”.
This document is not applicable to machines manufactured before the date of its publication.
