  2. Electrostatic-sensitive device - Wikipedia

    en.wikipedia.org/wiki/Electrostatic-sensitive_device

    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 which build up on people, tools, and other non-conductors or semiconductors. [1]

  3. IEC 61000-4-2 - Wikipedia

    en.wikipedia.org/wiki/IEC_61000-4-2

    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]

  4. Electrostatic discharge - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_discharge

    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.

  5. Human-body model - Wikipedia

    en.wikipedia.org/wiki/Human-body_model

    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 ...

  6. Process plant shutdown systems - Wikipedia

    en.wikipedia.org/wiki/Process_plant_shutdown_systems

    These systems may also be redefined in terms of ESD/EDP levels as: ESD level 1: In charge of general plant area shutdown, will also activate ESD level 2 if necessary. This level can only be activated from the main control room. ESD level 2: This level shuts down and isolates individual ESD zones and may activate if necessary EDP.

  7. Electrostatic discharge materials - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_discharge...

    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.

  8. Network Equipment-Building System - Wikipedia

    en.wikipedia.org/wiki/Network_Equipment-Building...

    NEBS (Network Equipment-Building System) describes the environment of a typical United States RBOC Central Office. NEBS is the most common set of safety, spatial and environmental design guidelines applied to telecommunications equipment in the United States.

  9. Conformance testing - Wikipedia

    en.wikipedia.org/wiki/Conformance_testing

    Electrostatic discharge (ESD) immunity Electrostatic discharges with various properties ( rise time , peak voltage, fall time , and half time ) are applied to the areas on the device that are likely to be discharged too, such as the faces, near user accessible buttons, etc. Discharges are also applied to a vertical and horizontal ground plane ...
