The spark associated with static electricity is caused by electrostatic discharge, or simply static discharge, as excess charge is neutralized by a flow of charges from or to the surroundings. The feeling of an electric shock is caused by the stimulation of nerves as the current flows through the human body.
The buildup and discharge of static can be minimized by controlling the surface resistance and volume resistivity of packaging materials. Packaging is also designed to minimize frictional or triboelectric charging of packs due to rubbing together during shipping, and it may be necessary to incorporate electrostatic or electromagnetic shielding ...
Conductive ESD bag with a network card inside ESD shoes. Electrostatic discharge materials (ESD materials) are plastics that reduce static electricity to protect against damage to electrostatic-sensitive devices (ESD) or to prevent the accidental ignition of flammable liquids or gases.
IEC 61000-4-2 is the International Electrotechnical Commission's immunity standard on electrostatic discharge (ESD). The publication is one of the basic EMC standards of the IEC 61000–4 series. The European equivalent of the standard is called EN 61000-4-2. The current version of the IEC standard is the second edition dated 2008-12-09. [1]
An antistatic device is any device that reduces, dampens, or otherwise inhibits electrostatic discharge, or ESD, which is the buildup or discharge of static electricity. [1] [2] ESD can damage electrical components such as computer hard drives, and even ignite flammable liquids and gases.
Warning symbol denoting a device's susceptibility to electrostatic discharge. Symbol for an ESD protection device – EPA Alternate warning symbol Symbol of an ESD grounding point for all components. An electrostatic-sensitive device (often abbreviated ESD) is any component (primarily electrical) which can be damaged by common static charges ...
A network card inside an antistatic bag. A pink static dissipative bag, and a silver conductive bag. Note the two recurring ESD symbols. An antistatic bag is a bag used for storing electronic components, which are prone to damage caused by electrostatic discharge (ESD).
Static discharge is also a particular hazard in grain elevators owing to the danger of a dust explosion, [131] in places that store explosive powders, [132] and in many other cases. [133] Triboelectric powder separation has been discussed as a method of separating powders, for instance different biopolymers. [ 134 ]
