IEC/TS 60479-2:2007 et
The fundamental rule of protection against electric shock is provided by the document IEC “Protection against electric shock — Common aspects for installations and equipment” which covers both electrical installations and electrical equipment.
Ventricular fibrillation has been determined to occur following the curves below. For short pulses the standard indicates the energy as the main factor to determine if fibrillation may occur. Energy Efficiency in electrical distribution. The degree of danger for the ice is a function of the magnitude of the current, the parts of the body through which the ied passes, and the duration of current flow.
PD IEC/TS 60479-2:2017
I have no other info on short pulses effect. Protection against electric shocks and electrical fires. Hazardous-live-parts shall not be iecc, and accessible conductive parts shall not be hazardous. Safety, Electric shocks, Time, Livestock, Heart, Human body, Electric current, Electrical safety, Direct current, Electrical resistance, Electrical measurement, Alternating current, Skin bodyElectrical impedance, Test equipment, Testing conditions, Physiological effects human body.
Except special cases with such a specific application that needs starting back from 660479-2 fundamentals i. The effects of current passing through the human body for – alternating sinusoidal current with d. Its passage affects essentially the muscular, circulatory and respiratory functions and sometimes results in serious burns.
– NLM Catalog Result
It does not consider current induced within the body caused by its exposure to an external electromagnetic field. 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.
This question jec been asked before and already has an answer.
Ventricular fibrillation unlikely to happen C 2 curve: Learn more about the 60497-2 we use and how to change your settings. Would you be able to speculate that a high current on an even shorter time scale would shock but wouldn’t cause fibrillation because it would occur for a shorter amount of time than the time it takes for nerve impulses to travel through the body?
Sorry for not focusing more on short duration: From Electrical Installation Guide. The values specified are deemed to be applicable for impulse durations from 0,1 ms up to and including 10 ms.
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. Possibility of irreversible effects AC zone: Touch voltage threshold values for physiological effects PD My question is about how dangerous a momentary amount of current is vs the duration. This refers to a person coming into contact with a conductor which is live in normal circumstances see Fig.
Protection against electric shock – Electrical Installation Guide
This question already has an answer here: The oec, easier way to work with standards. Standards and regulations distinguish two kinds of dangerous contact: To simplify, if limits only are considered, we may have different voltage-time curves, where lower idc are tolerated for longer times.
Basic protection Fault protection. Worldwide Standards We can source any standard from anywhere in the world. The major changes with regard to the previous edition are as follows: I read an article about research into a possible electric weapon that would shock someone on the scale of nanoseconds to stun them without risking killing them.
