what's the current of a static shock?

The lowest time on that graph is 10ms - a static shock (ESD event) is in the us/ns range.
Some interesting reading: http://ntuemc.tw/theme/design/EC_lecture%2010.pdf

That's an interesting graph, i've never seen it shown like that before.

It is also for AC current, but it seems to imply that above a certain current intensity, no matter how short the shock is, it can potentially cause some irreversible effect.
amyk:
If you really want to extrapolate it, then to me it seems AC-2 area would continue expanding to the right --- meaning "perceptible but no muscle reaction" occurs at very high current and very short durations.
bsfeechannel:
Well, in that case the lines will cross each other. But since the line separating AC-3 from AC-4 flattens out way before 10ms (which by the way is half a cycle for 50Hz AC), this may suggest that there is a limit for inoffensive currents running through your body no matter how short their duration is. I'd rather bet on that.
