Effects of Current on Human Beings and Livestock - Part 1: General Aspects
Also Known As:
IEC TS 60479-1:2005+AMD1:2016 CSV is a technical specification that provides guidelines and information on the effects of electric current on the human body and livestock. It specifically focuses on the danger to individuals and animals caused by the magnitude and duration of current flow through their bodies.
The standard recognizes that the time/current zones specified may not always be directly applicable in real-world situations when designing protective measures against electrical shocks. Instead, it emphasizes the need for considering the admissible limit of touch voltage, which is the product of the touch current and the body impedance, as a function of time. The relationship between current and voltage is non-linear due to the variation in body impedance with touch voltage.
The document describes the different components of the human body that electrical current interacts with, such as the skin, blood, muscles, tissues, and joints. The impedance of the body depends on factors such as the current path, touch voltage, duration of current flow, frequency, moisture of the skin, contact surface area, pressure exerted, and temperature. The values of body impedance presented in the technical specification are derived from experimental results obtained from measurements conducted on corpses and some living individuals.
It is important to note that IEC TS 60479-1:2005+AMD1:2016 CSV is classified as a basic safety publication, according to IEC Guide 104. This consolidated version includes both the fourth edition of the standard released in 2005 and its amendment 1 from 2016, making it unnecessary to order an additional amendment.
