Testing consumer equipment with a hand-held ESD simulator (ESD gun) An ESD simulator, also known as an ESD gun, is a handheld unit used to test the immunity of devices to electrostatic discharge (ESD). These simulators are used in special electromagnetic compatibility (EMC) laboratories.
A charged device model (CDM) test is used to define the ESD a device can withstand when the device itself has an electrostatic charge and discharges due to metal contact. This discharge type is the most common type of ESD in electronic devices and causes most of the ESD damages in their manufacturing.
The publication describes requirements, levels and test methods to achieve immunity compliance of an electronic product. The purpose is to create a reproducible ground for product compliance and the standard defines: ranges, levels, test equipment, setups, procedures, calibrations, generator waveforms and general uncertainties.
The two most common sensitivity test and analysis methods are the Bruceton analysis and Neyer d-optimal test. These methods allow the user to determine the 50% initiation level (the distance at which 50% of the samples will "go"), and a standard deviation. Impact testing may also be performed with liquid samples confined in special cells.
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 ...
In electrical engineering, transmission-line pulse (TLP) is a way to study integrated circuit technologies and circuit behavior in the current and time domain of electrostatic discharge (ESD) events. The concept was described shortly after WWII in pp. 175–189 of Pulse Generators , Vol. 5 of the MIT Radiation Lab Series.

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.
