Building construction machinery and equipment - Portable, hand-held, internal combustion engine driven abrasive cutting machines - Part 2: Machines for abrasive chains - Safety requirements (ISO/DIS 19432-2:2024)

This International Standard specifies safety requirements, and measures for their verification, for the design and construction of portable, hand-held, internal combustion engine-driven machines for abrasive chains, intended to be used by a single operator in the cutting of construction materials, such as concrete, stone and metal. It is applicable only to those machines designed purposely for use with a water-cooled abrasive chain only, where the top of the abrasive chain rotates away from the operator.
ISO 19432-2 is not applicable to:
Cut-off machines for centre-mounted rotating abrasive wheels, which are covered by ISO 19432-1.
Chain saws for forestry service, which are covered by ISO 11681-1.
Chain saws for tree service, which are covered by ISO 11681-2.
NOTE: Clarification of product class; machinery in the scope of this standard, is designed to only cut  construction materials, such as concrete, stone, metal and the like. The cutting means is by grinding with an abrasive chain through the work-piece, using a continuous water supply as a coolant, lubricant and dust suppression. This kind of machinery is not intended for use with conventional wood cutting saw chain with defined sharpened cutting edges.
This International Standard deals with all significant hazards, hazardous situations or hazardous events significant to these machines when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. (See Annex X for a list of significant hazards.)
This International Standard 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.
