Tools shall not emit harmful radiation, or present a toxic or similar hazard.Compliance is checked by the test, given in the relevant part of IEC 62841-2, IEC 62841-3 or IEC 62841-4, where necessary.NOTE Previous studies have shown that the level of electromagnetic fields (EMF) emitted by power tools and garden machinery, measured in accordance with IEC 62233, is far below the applicable limits, provided the sole significant source of EMF is the motor, which is typically a universal, DC (with or without brushes), induction or solenoid motor. Therefore, a general measurement in accordance with IEC 62233 was regarded as not necessary.
