HMM round robin study: What to expect when testing components to the IEC 61000-4-2 waveform

Abstract

ESDA Work Group 5.6, HMM (Human Metal Model), has conducted a round robin study using the HMM Standard Practice to determine reapeatability and reproducibility. Eight labs, using various ESD guns, 50 ohm and two-pin HMM pulsers show a range of results that highlights the variability allowed in the required waveform.
