ISO 28927-7:2009 specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of hand-held, power-driven nibblers and shears. It is a type-test procedure for establishing the magnitude of vibration in the gripping areas of a machine run under specified test conditions. It is intended that the results be used to compare different models of the same type of machine. ISO 28927-7:2009 is applicable to nibblers and shears, driven pneumatically or by other means, intended for cutting sheet metal or composite materials.
