Defines the effects on the human body when a sinusoidal alternating current in the frequency range above 100 Hz passes through it.

This part of IEC60479 describes the effects on the human body when a sinusoidal alternating current in the frequency range above 100Hz 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; alternating sinusoidal current with multicycle control are given but are only deemed applicable for alternating current frequencies from 15Hz up to 100Hz. Means of extending the frequency of applicability of pure sinusoids to a frequency of 150kHz are given, supplementing the data in IECTS60479‑1 . 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 0,1ms up to and including 10ms. This document only considers conducted current resulting from the direct application of a source of current to the body, as does IECTS60479‑1 and IECTS60479‑3 . 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 IECGuide104 and ISO/IECGuide51 . 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.
