A floor tile material used for the mitigation of electrostatic discharge (ESD). Usually composed of carpet, synthetic rubber or vinyl composition.
It is important to differentiate between the terms “SDT” and “static dissipative.” A static dissipative floor tile inherently meets the electrical properties of “static dissipative flooring” – without the use of antistatic waxes, finishes and glazes.
Floors are classified as static dissipative based on their electrical resistance. Dissipative materials measure > 1.0 x 106 and ≤ 1.0 x 109 ohms. Dissipative tile meets the required resistive properties (≤ 109 ohms) for a floor complying with the resistance to ground parameter in ANSI/ESD S20.20-2014.
Note: All static-control floors should be selected based on two parameters: Electrical resistance and walking body voltage. A dissipative floor tile can meet the resistance requirements of ANSI/ESD S20.20-2014 but fail to meet the walking body voltage requirement (< 100 volts.)
