Effects of current on human beings and livestock - Part 4: Effects of lightning strokes

Effects of current on human beings and livestock - Part 4: Effects of lightning strokes

IEC TR 60479-4:2020 (E) summarizes the basic parameters for lightning and its variability insofar as they apply to human beings and livestock.
The possible direct and indirect interactions of strikes with bodies of living beings are indicated. The resulting effects caused by lightning currents for the organism are described.
This document shows the differences of effects on human beings and livestock due to lightning strokes versus those effects of electric shocks derived from electrical systems.
This third edition cancels and replaces the second edition published in 2011. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) lightning occurence and climatory effects around the world are depicted;
b) direct strike description is extended;
c) step voltage effects are expanded;
d) upward streamer explanation is enhanced;

IEC 60479-2:2019(Main)
Effects of current on human beings and livestock - Part 2: Special aspects

IEC 60479-2:2019 describes the effects on the human body when a sinusoidal alternating current in the frequency range above 100 Hz passes through it.
The effects of current passing through the human body for:
– alternating sinusoidal current with DC components,
– alternating sinusoidal current with phase control, and
– alternating sinusoidal current with multicycle control
are given but are only deemed applicable for alternating current frequencies from 15 Hz up to 100 Hz.
Means of extending the frequency of applicability of pure sinusoids to a frequency of 150 kHz are given and means of examining random complex irregular waveforms are given.
This document describes the effects of current passing through the human body in the form of single and multiple successive unidirectional rectangular impulses, sinusoidal impulses and impulses resulting from capacitor discharges. The values specified are deemed to be applicable for impulse durations from 0,1 ms up to and including 10 ms.
This document only considers conducted current resulting from the direct application of a source of current to the body, as does IEC 60479-1. It does not consider current induced within the body caused by its exposure to an external electromagnetic field.
This basic safety publication is primarily intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51. It is not intended for use by manufacturers or certification bodies. One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications in the preparation of its publications. The requirements, test methods or test conditions of this basic safety publication will not apply unless specifically referred to or included in the relevant publications.
This first edition cancels and replaces IEC TS 60479-2:2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC TS 60479 2:2017:
a) change in status from Technical Specification to International Standard.

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