IEC/TR 60479-5 Ed. 1.0 b:2007

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.
