Human body electrification can be a major cause of electrostatic disasters. Typical conventional evaluation methods measure electrical resistance of installed floors. Despite their handiness, they do not provide a possible electrostatic potential, which is vital to assess a damage. This lead the authors to develop a quantitative and practical evaluation method for anti-static floors. A concept to simulate human body electrification on floors was proposed, followed by the development of an anti-static tester. The tester measures the maximum electrostatic potential (Vm) on the measured floor and decay time of the potential (Dt). Meanwhile, a scale for anti-static performance of floors (“U-scale”) was established by standardizing judgement of experts of floor finish. Finally, an equation was proposed to estimate U with Vm and Dt.
