IEC 61000-4-4 / SANS 61000-4-4

Testing and measurement techniques – Electrical Fast Transient / Burst

 

Tests:

Bursts of 5ns/50ns pulses at a repetition rate of 5kHz (which is the traditional choice) with a duration of 15ms and period of 300ms or 100kHz (which is more representative of real life) with a duration of 750µs, applied in both polarities between power supply terminals (also including protective earth) and a reference ground plane, or with the use of a capacitive coupling clamp onto I/O and communication lines.
