Description / Abstract:
This part of ISO 28927 specifies a laboratory method for
measuring hand-transmitted vibration emission at the handles of
handheld power driven portable die grinders. It is a typetest
procedure for establishing the magnitude of vibration in the
gripping areas of the machines where operating under type 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 handheld machines (see
Clause 5), driven pneumatically or by other means, equipped with a
collet and intended for deburring operations using hard metal burrs
or mounted points, on different materials ranging from hard steel
to plastics. It is also applicable to lowspeed die grinders using
flap wheels or cylindrical sleeves.
NOTE 1 It is not applicable to straight grinders equipped with
type 1 straight wheels, type 4 tapered wheels or different types of
cylindrical plugs. For those machines, ISO 289274 is
applicable.
NOTE 2 It is not applicable to die grinders used with wire
brushes.
NOTE 3 To avoid confusion with the terms "power tool" and
"inserted tool", "machine" is used hereinafter for "power
tool".
