BS EN 61000-4-19:2014

Pertains to the immunity requirements and test methods for electrical and electronic equipment to conducted, differential mode disturbances and signalling in the range 2 kHz up to 150 kHz at a.c power ports.

This part of IEC61000 relates to the immunity requirements and test methods for electrical and electronic equipment to conducted, differential mode disturbances and signalling in the range 2kHz up to 150kHz at a.c. power ports. The object of this standard is to establish a common and reproducible basis for testing electrical and electronic equipment with the application of differential mode disturbances and signalling to a.c. power ports. This standard defines: test waveforms; range of test levels; test equipment; test setup; test procedures; verification procedures. These tests are intended to demonstrate the immunity of electrical and electronic equipment operating at a mains supply voltage up to 280V (from phase to neutral or phase to earth, if no neutral is used) and a frequency of 50Hz or 60Hz when subjected to conducted, differential mode disturbances such as those originating from power electronics and power line communication systems (PLC). NOTE In some countries, the maximum voltage can be as much as 350V from phase to neutral. The immunity to harmonics and interharmonics, including mains signalling, on a.c. power ports up to 2kHz in differential mode is covered by IEC61000‑4‑13 . Emissions in the frequency range 2kHz to 150kHz often have both differential mode and common mode components. This standard provides immunity tests only for differential mode disturbances and signalling. It is recommended to perform common mode tests as well, which are covered by IEC61000‑4‑16 .
