component under test (CUT)
A passive or active element, device, integrated circuit, module or subsystem being tested. The CUT is intended to become part of a completed system but is not the entire system.
compressed gas ionizer
Ionization devices that can be used to neutralize charged surfaces and / or remove surface particles with pressurized gas. This type of ionizer may be used to ionize the gas within production equipment.
conductive flooring material
A floor material that has a resistance to ground of less than 1.0 x 106 ohms.
conductive material, resistance
A material that has a surface resistance of less than 1 x 104 ohms or a volume resistance of less than 1 x 104 ohms.
conductive material, resistivity
A material that has a surface resistivity less than 1 x 105 ohms/square or a volume resistivity less than 1 x 104 ohm-cm.
conductivity
a.The ratio of the current per unit area (current density) to the electric field in a material. Conductivity is expressed in units of siemens/meter.
b.In non-technical usage, the ability to conduct current.
constant area and force electrode (CAFÉ)
An electrode designed to be held by a person’s finger, gloved or ungloved, to reproducibly measure resistance from the finger to a counter electrode such as a ground strap worn on the wrist of the same hand. This electrode is suitable for measuring the resistance of a finger wearing a finger cot.
