Contents 1 – Introduction 1. When a current exceeding 30 mA passes near the heart of a human body, the person concerned is in serious danger if the 60479–1 is not interrupted in a very short time. The values of body impedance depend on a number of factors and, in particular, on current path, on touch voltage, duration of current flow, frequency, degree of moisture of the skin, surface area of contact, pressure exerted and temperature.
This refers to a person coming into contact with a conductor which is live in normal circumstances see Fig. Hazardous-live-parts shall not be accessible, and accessible conductive parts shall not be hazardous.

Preview Abstract IEC The degree of danger for the victim is a function of the magnitude of the current, the parts of the body through which the current passes, and the duration of current flow.
6479-1 – Protection against electric 6479-1 and electric fires. Residential premises and other special locations. The relationship between current and voltage is not linear because the impedance of the human body varies with the touch voltage, and data on this relationship is therefore required.
