This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it. It has the status of a horizontal standard in accordance with IEC Guide The timestamp is only as accurate as the clock in the camera, and it may be completely wrong. Relevant IEC standards include: Log-log graph of the effect of alternating current I of duration T passing from left hand to feet as defined in IEC publicationredrawn by CMG Lee based on http: 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.

Connection to the LV utility distribution network. This refers to a 604799 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.
Characteristics of particular sources and loads. Our prices are in Swiss francs CHF. This page was last edited on 14 Octoberat 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.

Protection against electric shocks and electrical fires. The following test report forms are related: 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. Hazardous-live-parts shall not be accessible, iev accessible conductive parts shall not be hazardous.
