This part of ISO28927 specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of hand-held power driven portable die grinders. It is a type-test 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 ISO28927 is applicable to hand-held 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 low-speed die grinders using flap wheels or cylindrical sleeves.
NOTE 1 It is not applicable to straight grinders equipped with type 1 straight wheels, type4 tapered wheels or different types of cylindrical plugs. For those machines, ISO28927-4 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\'.
