IEC Standards: IEC 61000-4-19: Test for Immunity to Conducted, Differential Mode Disturbances and Signaling

The IEC 61000-4-19 standard tests in the frequency range 2 kHz to 150 kHz at a.c. power ports. This standard defines test waveforms, range of test levels, test equipment, test setup, test procedures, and verification procedures.

These tests are intended to demonstrate the immunity of electrical and electronic equipment operating at a mains supply voltage up to 280 V (from phase to neutral or phase to earth, if no neutral is used) and a frequency of 50 Hz or 60 Hz when subjected to conducted, differential mode disturbances such as those originating from power electronics.
