One Hundred Megohms, or “One Hundred Meg,” equals one hundred million ohms or 1.0 x 108. The exponent 8 refers to the eight zeros after the 1. Staticworx® recommends an electrical resistance measurement of 1 x 108 as the maximum upper level for an ESD flooring specification.
Note: Many ESD flooring manufacturers recommend electrical resistance measurements as high as 1.0 x 109 (1 Billion ohms or One Thousand Meg).
Staticworx® believes that resistance measurements higher than 1.0 x 108 gives the flooring material too narrow a margin of error, and that the 900-million-ohm gap between 100 million and 1 billion ohms is too large a jump in electrical resistance. If a material has a resistance of 1.0 x 108, or 100,000,000 ohms, environmental changes and other mitigating factors should have little or no effect on the floor’s electrical performance. If a material has a resistance of 1 x 109 when it’s installed and low RH reduces conductivity or its resistance deteriorates over time, the floor may no longer provide adequate ESD protection.
With Staticworx ESD flooring, you never have to choose between performance and aesthetics. Our beautiful, high quality ESD carpet tile, vinyl, EC rubber tile and sheet goods, and ESD epoxy floors are as beautiful as they are functional.
