If something is anti static, does that mean it will conduct electricity?

The terms antistatic and conductive are independent of one another. When we describe a floor as antistatic, we mean that the floor will not generate static electricity charges under specific circumstances. Those circumstances could be limited to certain shoe sole materials like antistatic footwear or leather shoe soles. A floor does not necessarily need conductive properties - or to have the ability to conduct - in order to inhibit the build-up of static on people walking on it. However, ...

How long do conductive and static dissipative properties last in ESD flooring?

Properly designed, static control properties should last as long as the floor itself. Most conductive and static dissipative floors are manufactured using materials like carbon, graphite and silver. These are elemental conductive or dissipative materials. As long as these additives are bonded to the flooring in adequate concentration, they should provide static dissipation forever. Some ESD flooring materials lose their ability to eliminate static because of outside influences like maintenance. For example, ESD vinyl tile will become a static ...

How are static dissipative and conductive properties added to flooring?

Static control flooring differs from standard flooring. Unlike standard flooring, static control floors allow electricity to move across and through them. Regular flooring stores or holds electricity and generates static charges on the people who walk on it. Regular flooring cannot be grounded. Static control flooring dissipates or conducts electricity and other electrical currents to ground. Static control floors can be grounded.Almost any type of flooring can be made into a conductive or static dissipative floor. The most ...

Would I be better off with an antistatic or a conductive floor?

This question usually indicates a lot of confusion. Fortunately we have guidelines and standards to help us identify and properly specify the right floor. Finding the right floor means matching that floor to the specific needs of your environment. A floor that might perform very well in combination with antistatic footwear in an electronics manufacturing facility might be too conductive and also ineffective in a data center or 911 public safety dispatch operation because people wear regular footwear in ...

What is the difference between static dissipative and conductive flooring?

ESD floors are categorized based on their electrical resistance properties. Resistance is measure in ohms. A static conductive floor measures between 25,000 and 1,000,000 ohms also expressed as 2.5 X 10 E4 - 1.0 X 10 E6. A static dissipative floor measures between 1,000,000 ohms and 1,000,000,000 ohms also expressed as 1.0 X 10 E6 to 1.0 X 10 E9. Floors should never be purchased solely based ...

Is 'bare concrete' the best 'anti-static' flooring?

This question has as much to do with aesthetics, as it has to do with static control performance. Obviously if you are asking this question about your current facility, you are the only person who can answer the impact bare concrete has on the impression your floor will have on customers and visitors. However, from an electrical perspective, there are several factors that should be carefully considered. 1. Bare concrete can provide excellent electrical properties capable of meeting ...

Does the airflow create static electricity?

This is a common question with a straightforward answer. No, the airflow beneath an access floor poses no static threat whatsoever.Static electricity is generated by contact and separation. Airflow causes static electricity only when the air is particulate-laden and the particulates are large, meaning numerous and visible. For example, in sand and dust storms that occur in dry climates, sand and dust particles are blown into and away from billboards and plastic signs. The contact and separation between ...

Can new floors be installed over old?

This is one of those questions that should be answered only by a qualified flooring professional, based upon either a site inspection or a lengthy conversation. Almost any floor can be installed over an old floor as long as the old floor is in good condition and well-bonded to the sub floor. Some floors are much easier and less risky to install over old floors. Vinyl, for example, can be installed over existing vinyl. However, vinyl is stiff and ...

What flooring will prevent static in a data center - rubber or vinyl?

We are charged with recommending anti-static resilient flooring for a government client. This space is part of a data center that stores classified government information. Between vinyl and rubber - what is the difference and which flooring is more suitable for our application? Patrice AIA, LEED APAnswer:Both rubber and vinyl flooring can be manufactured with static dissipative or conductive properties. Used in conjunction with special static control footwear, either material would perform the same for your application. However, special ...

Which ESD Standards Are Easiest for Evaluating ESD Flooring?

Our company currently adheres to the same ESD standards as the ones you recommend on your website: The total system resistance of the person, footwear, walking surface and ground must be less than or equal to 3.5 x 107 or 35 meg-ohms maximum.However, at a recent ESD conference, attendees were told that an ESD floor can have a maximum resistance of 1 G Ohm (1 billion ohms), as long as the voltage generated in the walking test ...
