editions of 60601-2-2, was the reduction in the test voltage from 150% of the rated voltage of the accessory to 120% of that voltage. To justify this reduction in safety factor, IEC 60601-2-2:2006 places certain restrictions on the test waveform. DDL testing meets the new restrictions. In addition, the IEC standard requires that the high-frequency test be done first, followed immediately by the mains-frequency (e.g., 60 Hz) testing. There is also a significant change in the mains-frequency test... (read more)
