The predecessor to permanent static-dissipative and conductive flooring, computer-grade carpet contains a high density of bi-component yarns. Sometimes called low kV or antistatic carpeting, computer-grade floors will generate no more than 3500 volts of static electricity. These floors are not ground-able and have no ability to ground a static charge: because they have no conductive or dissipative properties, computer-grade floors cannot be tested with an ohm meter.
Designed to prevent nuisance static and nothing more, they are good ONLY for preventing shocks when people touch metal objects like a doorknob. A 3.5 kV-computer-grade floor is not intended or warranted for reducing charges to the minute thresholds necessary to protect static-sensitive electronic parts and systems.
