ESD floor testing procedure, ESD Bin Testing , ESD Trolly MYTHS ABOUT ESD FLOORING Additional notes when testing ESD floor testing procedure:- ESD floors are tested for electrical resistance and static generation. Resistance is measured with an ohmmeter, following either ASTM F150 or ANSI/ESD STM 7.1, by placing two 5 pound probes 3 feet apart on the floor, and applying 10 volts of electricity. WHAT IS ESD FLOORING, HOW DOES IT WORK Electrostatic Discharge (ESD) flooring protects electronics from damage caused by static electricity, which accumulates as people walk. Conductive elements such as carbon, graphite or metal-coated particles, distributed throughout the flooring material, give ESD floors electrical conductivity, and create an electrical pathway from the walking surface to ground. MYTHS ABOUT ESD FLOORING Myth 1: The more conductive a floor is the more efficient it is. Myth 2: The terms static dissipative and conductive are different, with different purposes. Myth 3: If a floor is conductive, it won’t generate static. Myth 4: If a floor is too conductive, using a less conductive adhesive will solve the problem. Shelves and table Testing:- Place one probe on the work surface, and one probe on the shelf. Your point-to-point resistance should be less than 1x10⁹ Ω ESD Floor and Table Testing:- Place one probe on the work surface, and one probe on the ESD floor. Your point-to-point resistance should be less than 1x10⁹ Ω Common Point Ground Testing:- Place probe on the tabletop and measure the system’s total resistance between the tabletop and the common point ground using a measuring lead ESD Carts Testing:- Place one probe on the cart’s shelf, and one probe on a metal plate under the cart’s ESD caster. Your point-to-point resistance should be less than 1x10⁹ Ω For best results, ensure cart casters/wheel have been cleaned with ESD detergent ESD Chairs Testing:- Place one probe on the seat of the chair, and one probe on a metal plate under one of the chair’s wheels. Your point-to-point resistance should be less than 1x10⁹ Ω (with upcoming standard less than 1x1010 Ω) For best results, ensure chair wheels have been cleaned with ESD detergent Additional notes when testing:- Relative air humidity will affect resistance levels. Dirt in between measured surfaces (incl. probes) will affect resistance levels. Commonly used detergents contain a wax component. Wax will create an insulative layer on surfaces like tabletop and floor. Use ESD -compatible detergent. Insulators must be measured by a field meter. IEC 61340-5-1 defines allowed values/distances.
