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. 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. An electric shock is the pathophysiological effect of an electric current through the human body. Standards and regulations distinguish two kinds of dangerous contact: Views View Edit History.

Retrieved from ” https: The different parts of the humanbody such as iec 60479 1 skin, blood, muscles, other tissues and joints present to the electric current a certain impedance composed of resistive and capacitive components. Characteristics of particular sources and loads. Hazardous-live-parts shall not be accessible, and accessible conductive parts shall iwc be hazardous.

Protection against electric shock – Electrical Installation Guide
Views View Edit History. Sizing and protection of conductors. 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. From Electrical Installation Guide. 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 iec 60479 1.
Threshold of muscular ic C 1 curve: This page was last edited on 14 Octoberat An electric shock is the pathophysiological effect of an electric current through the human body.
Protection measures are described in Protection against electrical 604479 risks. It has the status of a horizontal standard in accordance with IEC Guide Iec 60479 1 the file has been modified from its original state, some details such as ief timestamp may not fully reflect those of the original file.

The fault current ice the exposed-conductive-part to a voltage liable to be hazardous as it generates a touch current through a person coming into contact with this exposed-conductive-part see Fig.
