This means that you estimate touch voltage for a conductive part enclosure, cable shield, pipe, etc. The effects of current passing through the human body for – alternating sinusoidal current with d.

This refers to a person coming into contact with an exposed conductive-part which is not normally live, but has become live accidentally due to insulation failure or some other cause.

In reality, a short pulse has a high frequency content, so at a first approx the expected behavior is iiec. Your basket is empty. This is what distinguishes applications: Actually I was specifically interested in short duration D.

For impulse durations greater than 10 ms, the values given in Figure 20 of IEC apply. I edit the answer and include also the figure 22 for dc.

I guess that the time factor consideration occurred to me after thinking about people who had survived lightning, which has a huge amount of current but only occurs for a tiny fraction of a second.

Possibility of irreversible effects AC zone: When a current exceeding 30 mA passes near the heart of a human body, the person concerned is in serious danger if the current is not interrupted in a very short time.

To simplify, if limits only are considered, we may have different voltage-time curves, where lower voltages are tolerated for longer times.
