Conventional touch voltage limit
The highest permissible touch voltages (conventional touch voltage limits) are given in
Table 4. The current, which flows through the human body, depends not only the touch
voltage and body impedance but also the impedance the surface which the human being
stands which touched, and also the conditions the surface.
