Effects of current on human beings and livestock - Part 5: Touch voltage threshold values for physiological effects

This Technical Report provides **touch voltage-duration combination thresholds** based on analysis of information concerning body impedances and current thresholds of physiological effects, as given in IEC/TS 60479-1. Such threshold combinations relate to specific environmental and contact conditions that determine body impedance for particular current pathways.

This technical report considers only:

  • (i) 50/60 Hz sinusoidal alternating voltage having no other frequency components and no significant direct voltage component, and
  • (ii) direct voltage with no significant alternating component.

This technical report provides thresholds as a result of calculations based on values from IEC/TS 60479-1, with uncertainties. Therefore thresholds proposed in this report also correspond to values with uncertainties.

Touch voltage-duration combination thresholds are for use by technical committees as guidance for the determination of limits for touch voltage and touch voltage durations in various environmental situations.
