Electrostatic discharge (ESD) is a sudden and momentary flow of electric current between two differently-charged objects when brought close together or when the dielectric between them breaks down, often creating a visible spark associated with the static electricity between the objects.
A hose reel is a cylindrical spindle made of either metal, fiberglass, or plastic and is used for storing a hose. The most common styles of hose reels are spring driven (which is self retracting), hand crank, or motor driven. Hose reels are categorized by the diameter and length of the hose they hold, the pressure rating and the
Warning label for an electrostatic sensitive device, denoting the devices susceptibility to damage. A similar symbol without the bar and with a black "dome" denotes ESD-safe equipment. The human-body model ( HBM ) is the most commonly used model for characterizing the susceptibility of an electronic device to damage from electrostatic discharge ...
Corona discharge — occurs at sharp points and edges (radius < 1 mm). It is a uniform ionization (glow discharge) visible as a dim stationary blue glow, fading out as it extends from the conductor. Brush discharge — occurs at a curved electrode (radius between 5 and 50 mm) [3] in the vicinity of a flat electrode. It consists of a short ...
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 electrostatic-sensitive device (often abbreviated ESD) is any component (primarily electrical) which can be damaged by common static charges which build up on people, tools, and other non-conductors or semiconductors. [1] ESD commonly also stands for electrostatic discharge.
