Carpet Testing
Electrostatic Testing
Static coefficient of friction
(ASTM C 1028)
Static coefficient of friction: Discharge of electrostatic potential from carpet o person to conductive ground, e.g., a doorknob. Shoe friction against carpet fiber causes production of electrostatic charge. Charges above 3500 volts may produce discomfort. Various static control systems and finishes are used in contract carpet to dissipate static charge before it builds to the human sensitivity threshold.
