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. The contents of the corrigenda of October and June have been included in this copy. Personal tools Create account Log in. When a current exceeding 30 mA passes near the heart of a human body, the person concerned is in serious danger if the current is not interrupted in a very short time.

MV and LV architecture selection guide for buildings. Threshold of perception of current B curve: The relationship between current and voltage is not linear ifc the impedance of the human body varies with the touch voltage, and data on this relationship is therefore required.

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. This refers to a person coming into contact with an exposed conductive-part which is not normally live, but has become live accidentally due to insulation failure or some other cause.
