1. (Note-Many ESD flooring manufacturers will recommend electrical resistance measurements as high as 1.0 x 109, (1 Billion ohms or "One Thousand Meg"). However, Julie Industries feels that the gap between 100 million ohms to a 1 billion ohms is too large, (900 million ohms), of a jump in electrical resistance. If the material's electrical resistance happens to deteriorate over time, beginning at 1.0 x 109, it may not provide adequate ESD protection over a long period of time.)

2. 25,00 Ohms:
This is represented by the scientific notation 2.5 x 104, or 2.5 x 10,000 ohms. This is the lowest end of the conductivity range. Anything lower than this range is considered an electrical shock hazard.

3. AATCC 134:-(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.

4. Above Grade Flooring-A floor that is raised above the ground, leaving at least 18 inches of well ventilated space.

5. ANSI/ESD S20.20-1999:
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.

6. Antistatic Bi-component:-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.

7. Antistatic Carpet-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.

179. Mission Critical:-Literally, any operation that cannot tolerate intervention, compromise or shutdown during the performance of its critical function. Mission critical environments usually support health, safety, security and human welfare. These environments also monitor, store, support and communicate data that cannot be lost or corrupted without compromising their core function. Since all computer and communications systems are highly sensitive to static electricity, static events pose an internal threat to mission-critical operations, such as flight control towers, energy management operations, 911 centers, command centers, dispatch, control rooms, data storage centers, hospitals, stock exchanges, laboratories, university research facilities, computer rooms—any space where the loss or corruption of data cannot be tolerated. Conductive flooring is a mandatory element in mission critical environments, because it prevents and discharges static electricity before it becomes a problem.

This test was originally designed in the 1960's for use in hospital operating rooms that used explosive gases for anesthesia. Operating room surfaces were required to be conductive so that static fields would be safely discharged to ground instead of dangerously discharged as a spark that could ignite an explosion
