Is ESD epoxy appropriate for a small server room?
Although we appreciate your interest in our epoxy ESD flooring, we need to caution you about the limitations of static dissipative or conductive epoxy coating in a data center/server room application.All ESD coatings are formulated to eliminate static build-up by providing a ground path. The ability to be grounded is achieved by adding either conductive fibers or carbon and graphite particulate. The fibers and particulate create an electrical bridge through a resinous coating that otherwise, is an insulating ...View Answer
Are there any scientific studies about the performance of anti static flooring or conductive flooring for mission critical environments or data centers?
Conductive flooring should never be used in end user operational equipment environments. There is consensus among standards organizations that static dissipative flooring is the correct ohms range for end user environments. This White Paper documents an independent study showing that a static dissipative floor will perform as well or better than a conductive floor for mission critical applications. A static dissipative floor measures above 1 million ohms and fewer than 1 billion ohms. You will often see these values expressed ...View Answer
Can you explain the differences between low static and anti-static with grounding?
Questions about the differences between what we commonly call “antistatic carpet” versus “permanent static control carpet” (also known as ESD carpet) usually get raised at some point in every project. The distinction is critical. Numerous flooring products are bought with the belief that they are antistatic when in fact - they often are, or become, static generators. When that misapplication involves the choice of flooring for common office space or a hotel lobby, ...View Answer
I have a #6 AWG copper conductor and the copper strip/tape - how to I best MATE those together ? Or how do I ensure conductivity across the floor?
What you're really asking is this: how do I ensure continued conductivity across the static control floor? The answer must involve your choice of static control flooring.First, there are several different types of static control floor covering. All possess different properties and some of the floor coverings have limitations. For example, Armstrong manufactures a product called SDT. Armstrong SDT requires special waxes to make it perform. Some antistatic broadloom cannot be grounded at all because it is not ...View Answer
Does it do any good to have ESD chairs if the floor is not ESD?
A chain is only as good as its weakest link. In an electrical chain, a weak link creates a breach in conductivity. A loose or disconnected wire is the simplest example: If a wire is loose or a cord is unplugged, the chain ends; the electrical current does not reach its intended target. With static control, the idea is to discharge the built-up (static) electrical current to ground. A person can wear a wrist and/or heel strap and sit ...View Answer
How do I ground non-esd materials and carts to a conductive tile floor?
Add conductive drag chains and casters to materials and carts to ground them to esd flooring. The photo to the right shows a recently completed Conductive Vinyl tile installation. This client plans to use "wire shelf carts" to move electronics assemblies around the floor. Even though this floor is grounded and conductive, the cart will not be grounded as its wheels are insulators. Static cannont drain through an insulator even if that insulator is resting on an esd, anti ...View Answer
Why should I worry about moisture protection with ESD flooring?
Moisture permeation through concrete slabs can wreak havoc with all types of flooring. Several years ago, the Rubber Association determined that levels exceeding 3 pounds of moisture per 1000 square feet per 24 hour period caused serious problems, such as delamination, adhesive breakdown and adhesive oozing. High moisture can also lead to the development of bacteria and molds, which, in addition to causing foul odors, contribute to sick building syndrome. The industry standard test for moisture permeation is the ...View Answer
How does relative humidity affect the performance of an ESD floor?
Static generation occurs more easily when the climate is dry. Static also stores better on surfaces when the air is dry. Sometimes an ESD floor will appear to perform when the humidity is over 40 percent. This is quite normal with carpet. Any ESD carpet should be tested at least as low as 12 percent relative humidity. Unless the carpet is loaded with carbon fibers, most carpets will fail below 20 percent RH....View Answer
Do conductive and static dissipative tiles need to contact one another in order to be grounded?
Static control tiles dissipate static from the top of the tile to the bottom of the tile - not side to side. If we place two tiles tightly against each other and measure electrical continuity from the top of one tile to the top of an adjacent tile, we would likely measure a very high resistance. A high resistance indicates no electrical continuity between static control tiles. The conductive adhesive eliminates this problem. Conductive adhesive acts as an electrical ...View Answer
Could a conductive floor endanger people working around operational energized equipment?
Standards organizations do not recommend conductive flooring in end user operational equipment environments. Conductive flooring offers no static control advantage over static dissipative flooring in controlling static accumulation on people walking on the floor. For example, this August, 2011 independent lab study compares the charge generation performance of static dissipative carpet tile against conductive carpet tile. The static control results are nearly identical with the slight advantage in favor of the static dissipative carpet. Keep in mind that a conductive floor ...View Answer
