This part of ISO 28927 specifies a laboratory method for measuring handtransmitted
vibration emission at the
handles of handheld,
powerdriven
saws, polishing and filing machines with reciprocating action and small
saws with oscillating or rotating action. It is a typetest
procedure for establishing the magnitude of vibration in
the gripping areas of a machine run under specified test conditions. It is intended that the results be used to
compare different models of the same type of machine.
This part of ISO 28927 is applicable to reciprocating files intended for surface finishing equipped with a file or
polishing tool, saws intended for parting sheets, plaster for medical use or wood, or equipped with a saw blade
for use on all kinds of materials, and small circular saws primarily intended for cutting metal or composite
materials (see Clause 5), whether driven pneumatically or by other means. It is not applicable to files that are
normally used with one hand on the file blade, nor to large circular saws intended for cutting wood.
NOTE To avoid confusion with the terms “power tool” and “inserted tool”, machine is used for the former throughout
this document.
