ISO 8662-4:1994

The method specified is a laboratory type-test procedure for establishing the magnitude of vibration in the handle of a power tool fitted with a specified test wheel. Applies to power tools that may be pneumatically driven or driven by other means. It is intended that the results be used to compare different models of the same type of power tool, i.e. power tools intended for use with the same grinding wheel (same diameter and same maximum peripheral speed).
