Doug: I believe the waveforms would be very similar in their waveshape for the initial peak current. The IEC 61000-4-2 specification requires you to verify the waveform at the initial peak current and the 30 and 60 ns time intervals. The ISO 10605 spec has the verification of the waveform at the initial peak current and requires the measurement of the RC time constant. If you compare the initial peak current readings for both specifications, they are basically the same value.
The main difference between the two specs is the different RC networks required for testing. This is where the waveshapes will differ. The ISO 10605 specification relates to the ESD events in Road Vehicles whereas the IEC 61000-4-2 spec relates to ESD events in many electrical components/systems. The IEC spec calls out an RC network of 150pF/330 ohms where the ISO spec calls out 330 pF/2000 ohms and 150 pF/2000 ohms.

Is the discharge waveform the same? Thanks, Doug This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
