This document specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of hand-held power-driven angle and vertical 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 no-load conditions. The method has been established for surface grinding tasks only. Cutting and sanding generally create lower vibrations. It is intended that the results be used to compare different models of the same type of machine.Cross References:ISO 20643:2005ISO 5391ISO 2787ISO 17066ISO 5349EN 755-2EN 12096ISO/TR 27609IEC 60745ISO 603-14ISO 603-16ISO 6103ISO 630-2ISO 5429ISO 12100All current amendments available at time of purchase are included with the purchase of this document.
