The term conductive floor is often misconstrued as too conductive. Unlike highly conductive materials like copper and steel, conductive flooring is actually relatively resistive. Conductive floors like static dissipative floors are classified based upon their electrical resistance to ground. Electrical resistance is measured in ohms of resistance. The resistance to ground of a properly specified conductive floor is ≥ 2.5 X 104 and < 1.0 X 106 measured per ANSI/ESD STM7.1 Conductive flooring always meets all three recommended electrical parameters of ANSI/ESD S20.20. A type of flooring intended to prevent, mitigate, dissipate, conduct, remove or ground excessive static electricity charges on people, furniture, mobile carts and equipment. Static conductive flooring should not be confused with highly conductive materials including: copper, aluminum, silver, brass and gold. Unlike highly conductive materials, static conductive materials - by definition - possess an intrinsic electrical resistance of greater than 25,000 ohms per ANSI/ESD S7.1. 25,000 ohms resistance is the amount of resistance recognized in NFPA 99 standard for healthcare facilities. Static conductive flooring meets all the criteria for flooring in for use in an ESD control programs in ANSI/ESD S20.20. Static conductive flooring provides superior static control performance vs. static dissipative flooring. Independent testing has shown that rubber static conductive flooring will successfully inhibit static electricity on person wearing any kind of footwear.
