(American Association of Textile Chemists and Colorist), Electrostatic propensity of carpets test methodology measures the floors tendency to generate a charge. Simply stated, it measures the amount of static generated by a Neolyte shoe sole stepping on a carpet surface in a controlled room environment at 72 degrees Fahrenheit and 20% R.H.


Protection of Electrical and Electronic Parts, Assemblies and Equipment (Excluding Electrically Initiated Explosive Devices covers the requirements necessary to design, establish, implement, and maintain an ESD control program to protect electrical or electronic parts, assemblies and equipment susceptible to ESD damage from Human Body Model (HBM) discharges greater than or equal to 100 volts


The term antistatic refers to a condition where static generation is inhibited during contact and separation with a different material. Anti static flooring can either be static dissipative or static conductive...


A type of yarn commonly found in most commercial and household carpets. The term bi-component refers to the co-extrusion of two materials within the same yarn strand. The internal cross-section of the yarn contains carbon while the surrounding fibers are composed of standard insulative nylon. The bi-component yarn provides an overall reduction in static generation—not a path to ground. Because the outer nylon insulates the internal conductive element, bi-component yarns do not discharge or conduct static electricity. Bi-component yarns cannot be grounded and are not suitable for static control in areas where computers are used.


The term antistatic refers to a condition where static generation is inhibited during contact and separation with a different material. In general, antistatic carpet is any carpet product that will generate less static electricity than standard carpet. Antistatic carpet is not conductive and it is not possible to ground anti-static carpet. Antistatic carpet usually contains bi-component yarns. The reason for specifying antistatic carpet is to establish a space that will be free of static shocks, or zaps. Most new antistatic carpet will prevent shocks as long as the relative humidity (RH) is above 25%. Anti static carpet should NOT be confused with conductive or ESD carpet. Antistatic is not a permanent property.


A separate supplemental grounding conductor for use other than general equipment grounding.
