Computer grade carpet is the predecessor to conductive and static-dissipative carpet. Designed during the infancy of the information age, computer grade carpet contains a high density of bi-component antistatic yarns. Like all antistatic carpet, it cannot be grounded.
The antistatic properties of computer grade carpet are usually described by obsolete commercial standards, such as the IBM/Burroughs standard which grades carpet by its kV rating (see low kV). A carpet specified for use around computers and other electronic equipment should be evaluated by kV rating (walking body voltage) and resistance to ground (measured in OHMS).
