This part of ISO 28927 specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of straight grinders. It is a type-test procedure for establishing the magnitude of vibration in the gripping areas of a machine fitted with a specified test wheel and run under noload conditions.
This part of ISO 28927 is applicable to hand-held machines (see Clause 5), driven pneumatically or by other means, intended for grinding and surface finishing using straight grinding wheels type 1, tapered wheels type 4 and cylindrical plugs, e.g. of type 16 (cylindrical plug, tapered cone), 18 (cylindrical plug, flat end), 18R (cylindrical plug, rounded end) and 19 (cylindrical plug, taper-roll shaped) and with wire brushes, for use on all kinds of materials. It is not applicable to die grinders where the inserted tool is mounted in a collet.
NOTE 1 Typical machines covered by this part of ISO 28927 are illustrated in Figures 1 to 3.
It is intended that the results be used to compare different models of the same type of machine.
NOTE 2 To avoid confusion with the terms "power tool" and "inserted tool", "machine" is used hereinafter for the former.
