FAQ: Would I be better off with an antistatic, static-dissipative or a conductive floor?

First, let’s be clear about terms: for specificity and to help avoid confusion, the terms “static-free” or “anti-static” were recently changed to “low charge generating.” A floor described as static-free, anti-static, or low charge generation won’t contribute to triboelectrification. This means, when people walk, the floor won’t generate static on the soles of their shoes. A low-charge generating floor is not necessarily a grounded floor. Only conductive and static-dissipative materials (materials measuring < 1.0 x 10E9)—or materials that transport electrical current—can be grounded.

Grounded ESD Floor

Illustration demonstrating how ESD flooring is grounded. Conductive elements in ESD flooring transport static charges from people or objects on the floor to the conductive ground plane (conductive adhesive or underlayment); charges then flow across the conductive ground plane to copper strips at the periphery of the room, connected to some form of earth ground.
ESD floors provide a safe and effective path to ground. Only floors that transport electrical current can be grounded.

The fact that a floor exhibits low-charge-generating tendencies does not mean it will also dissipate static properly. Static dissipation, and therefore conductivity, is unrelated to charge generation; one has nothing to do with the other. The ability of a floor to discharge—or dissipate—static is related to its conductivity, which is evaluated based on electrical ohms resistance tests. Charge generation is expressed in volts.

Illustration on a gray background titled "ANSI/ESD STM7.1 Resistance Tests". On the right side a "Point to Point" test set up is shown, with two probes connected to a surface analog resistance meter and placed 36" apart on the surface being tested. On the right side, the "Point to Ground" set up is shown with a surface analog resistance meter connected to ground and also to a probe on the surface being tested.
Electrical resistance is measured in ohms, from point to point (Rtt) and point to ground (Rtg), using a meter called an ohmmeter.

Finding the right static-control floor means matching the floor to the specific needs of the environment. A conductive floor that performs well in an electronics facility, where people are required to wear static-protective footwear at all times, might be ineffective in a data center or 9-1-1 public safety dispatch operation where people wear regular street shoes.
