Hazardous-live-parts shall not be accessible, and accessible conductive parts shall not be hazardous. Relevant IEC standards include: This question has been asked before and already has an answer. Except special cases with such a specific application that needs starting back from the fundamentals i.

IEC/TS 60479-2:2007 et

When a current exceeding 30 mA passes near the heart of a human body, the person concerned is in serious danger if 6047-2 current is not interrupted in a very short time. For short pulses the standard indicates the energy as the main factor to determine if fibrillation may occur.

My question is oec how dangerous a momentary amount of current is vs the duration. Take the smart route to manage medical device 604479-2. Contents 1 – Introduction 1. Threshold of muscular reactions C 1 curve: Ventricular fibrillation has been determined to occur following the curves below. 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 ie, Physiological effects human body.

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.


This standard furthermore describes the effects of current passing through the human body in the form of single unidirectional rectangular impulses, sinusoidal impulses and impulses resulting from capacitor discharges.

Characteristics of particular sources and loads. 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. It does not consider current induced within the body caused by its exposure to an external electromagnetic field.

Touch voltage threshold values for physiological effects PD Residential premises and other special locations. Our prices are in Swiss francs CHF. This website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3.

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.

IEC For short pulses the standard indicates the energy as the main factor to determine if fibrillation may occur. Ventricular fibrillation unlikely to happen C 2 curve: Protection against electric shocks and electrical fires.

The major changes with regard to the previous edition are as follows: This means that you estimate touch voltage for a conductive part enclosure, cable shield, pipe, etc.

Sizing and protection of conductors. Yes I’ve read that, but is it less likely to do so if it occurs for an extremely small time period? The threshold of pain for current flowing between extremities is in the order of 0. An electric shock is the pathophysiological effect of an electric current through the human body. Contact with live part Direct contact. Chapter – Protection against electric shocks and electric fires.


This has been addressed many times on this site already. We use cookies to make our website easier to use and to better understand your needs. See IEC Figure 20 and 22 below for ac and dc systems, respectively, and Table 11 and 13, again for ac and dc, for interpretation.

I will dig into it. Sorry for not focusing more on short duration: I have no other info on short pulses effect. Personal tools Create account Log in. Worldwide Standards We can source any standard from anywhere in the world.

Safety of current with duration – Electrical Engineering Stack Exchange

Electrical fires are caused by overloads, short circuits and earth leakage currents, but also by electric arcs in cables and connections. Actually I was specifically interested in short duration D. You may find similar items within these categories by selecting from the choices below:. Find Similar Items This product falls into the following categories. Preview Abstract IECwhich is a technical specification, describes the effects on the human body when a sinusoidal alternating current in the frequency range above Hz passes through it.

Of less interest if considering typical waveforms of supply distribution and equipment, but covering waveforms purposely generated, capacitor discharge, arc phenomena.
