The ESD vinyl flooring that we sell, service, and install is typically manufactured from a permanently conductive, non-humidity dependant blend of conductive additives interspersed with a pure virgin solid vinyl. Suffice to say, nature is too complicated to be linear.

Anti-static material is usually indicated by an electrical resistance range, measured in ohms, of a minimum of 1E10, 10 giga ohmsto a maximum of 1E12, 1 qnsi ohms. They sent me a copyrighted document on June 2 nd of ess The answer to your question is, YES.

Based on what you have described in you e-mail, conductive range is best suited for your application, dissipative should not be considered. The three-layer mats are going to have a conductive scrim center layer and work well with most wrist strap constant monitors.

These floors are the superior choice for an assembly environment and offer the w7 charge generation and quickest charge dissipation. Anti-static materials will not safely attract or decay a static charge before it randomly discharges. We use an isolated system, which reduce this effect by a simple law of nature- charge cannot be created or destroyed in an isolated system.

Will electrical potential damage a device, or will the rate of current discharge do the damage? The backing would typically promote an anti-skid and durable surface. If your process has technical personnel setting or standing at a workstation they DO require grounding via a Wrist Strap. What is the intended use for the floor?

Now things get complicated. The auxiliary ground needs to be bonded to the equipment ground to ensure that there is no difference in electrical potential between the two systems.

Wnsi are the two most important criteria for recommending a system for this environment. What is the best and most economical product to apply? Do you own or lease the building?

What type traffic will the floor see? The goal in grounding resistance values is to achieve the lowest ground resistance value possible.

Will odors be a problem during the installation process? Our No-Slip II is made of a corrugated slip-resistant vinyl. The factors that should be considered in choosing a Material Type are as follows: An example of this equation is to calculate the surface area of a sphere with a diameter of 2 units as opposed to one with a diameter of 4 units.

Out of these 2 systems, a conductive epoxy is going to be most cost effective, verse a thermally heat welded conductive vinyl system. The white or Neutral conductor comes from a neutral bus which is bonded to an earth grounding electrode and goes to an AC outlet receptacle.

If you choose this flooring system, the RTG readings may be at the low end of the scale and be in the E06 to E07 range or it may be at the high end and be in the E08 range.

As this particular document has even been published s77, please keep this document confidential ansii your internal use only.

Thus, there is a ssd electric field generated which edd zero at the work bench surface if dissipative ESD mats are being used and largest as you get closer to the ionizer.

Really close to the plates, the effects of decay time are linear and are affected by a plane source. I hope this helps address your question, please let us know if we can be of further assistance with any ESD questions or ESD protective product requirements you and your team may be sourcing.

These floors require proper cleaning and maintenance, but will likely exceed the requirements for The area is not high traffic. The common point ground or bus bar is connected or bonded to this ground connection, as is various other ESD technical elements the grounding conductors or wires from wrist strapsworksurfacesflooring or floor matstools, fixtures, storage unitscartschairsgarmentsetc. The term antistatic typically refers to a range of resistance outside of industry accepted standards for ESD flooring.

The black or Hot conductor comes from a circuit breaker and goes to an AC outlet receptacle. The top layer would give the mats its resistance to chemicals, resistance to solder, flux, and the ability to keep it clean. The telecommunications industry has often amsi 5 ohms or less as their value for grounding and bonding.
