Static decay test
A static decay test is a procedure in which an item is first charged to a specified voltage, then allowed to dissipate to a specified voltage while measuring the duration of the discharge.

Surface resistance
Surface resistance is the resistance of a surface measured by a concentric ring electrode test method defined in 61340-5-1 and IEC 61340-2-3: 2000. It is the ratio of DC voltage to the current flowing between two electrodes of specified configuration that contact the same side of a material. This measurement is expressed in ohms.
Static control
Static control is a generic term for measures taken to diminish the effects of electrostatic discharge. Anti-static products such as ESD mats, ESD bags or conductive flooring are used to create an ESD protected area where static is controlled.
Static dissipative
Static dissipative refers to increased resistance, which protects better against an ESD i.e. between 1 meg-ohm (10^6) and 1000 meg-ohm (10^9). Static dissipative materials allow any static charge to be dispersed. Charge transfers from static dissipative materials are slower than from conductive materials and are significantly faster than from insulators. Products such as ESD clothing and ESD […]
Static generation
An example of static generation is when people walk across a floor, the friction between the soles of their shoes and the surface of the floor generates static—also called walking body voltage.
Static electricity
Static electricity is a stationary electrical charge/ field, typically produced by friction, which causes sparks, crackling or the attraction of dust or hair. All items are made of small atoms. These atoms are made up of even smaller items called protons, neutrons and electrons. The protons are charged positive, the neutrons have no charge and the electrons […]
Resistance to groundable point
Resistance to groundable point is the resistance in ohms measured between a single electrode placed on a surface and a groundable point.
Resistance to ground
Resistance to ground is the resistance in ohms measured between a single electrode placed on a surface and ground.
Resistance range
Resistance range refers to a user-specified upper and lower resistance values which define the user-acceptable resistance values of a wrist strap or wrist strap system.
Point-to-point resistance
Point-to-point resistance is the resistance in ohms measured between two electrodes placed on any surface.
