Title & Task

MT 4

Effects of current passing through the body


The task is to provide basic guidance on the effect of current
shocks on human beings and livestock, for use of drafting of
electrical safety requirements.

The result of this work is mainly used by TC 64 as a basis for
fixing requirements for protection against electric shock. It
may serve also as a guide to other IEC committees and countries
needing such information. In particular WG 4 is dealing with
limits of ventricular fibrilation which is the main cause of
death by electric current shocks. The results of physiological
research have to be implemented to better appreciate the
influence of the main physiological parameters on threshold of
perception, reaction, let-go and ventricular fibrilation.
