DIN EN ISO 28927-4:2011-05

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 which must be stated in the instruction manual. This part of ISO 28927 applies to hand-held machines intended for grinding and surface finishing using straight grinding wheels type 1, tapered wheels type 4, and cone wheels type 16, 18, 18R and 19, for use on all kinds of materials. It does not apply to grinders used with wire brushes and die grinders. The machines covered by this part of ISO 28927 may be pneumatically driven, or driven by other means.
