Abstract

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. The contents of the corrigendum of July 2013 have been included in this copy.
