It is important to discharge at a slow rate, therefore a resistor should be used in grounding the mat. The resistor, as well as allowing high-voltage charges to leak through to ground, also prevents a shock hazard when working with low-voltage parts. Some ground mats allow one to connect an antistatic wrist strap to them. Versions are designed ...
Grounded-gate NMOS, commonly known as ggNMOS, is an electrostatic discharge (ESD) protection device used within CMOS integrated circuits (ICs). Such devices are used to protect the inputs and outputs of an IC, which can be accessed off-chip (wire-bonded to the pins of a package or directly to a printed circuit board) and are therefore subject to ESD when touched.
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.

In aircraft, electrical bonding prevents static electricity build-up that can interfere with radio and navigational equipment. Bonding also provides lightning protection by allowing the current to pass through the airframe with minimum arcing. Bonding prevents dangerous static discharges in aircraft fuel tanks and hoses. [3]
Static buildup, as induced by friction for example, such as when wind blows onto a radio mast, is dissipated to the Earth. [2] In the event of a surge, a lightning arrester , a surge arrester or a surge protection device (SPD) will divert the excess current to the Earth before it reaches an appliance.
Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it can move away by an electric current or electrical discharge. The word "static" is used to differentiate it from current electricity, where an electric charge flows through an electrical conductor. [1]
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.
