How to specify static-free flooring in different types of spaces

Your engineer is correct on both counts. Some static control carpet tile is extremely conductive (too few ohms resistance) and should be reserved strictly for use in spaces where footwear is controlled and measured for resistive properties. Sometimes these spaces are called EPAs. EPAs are segregated areas inside electronics manufacturing and handling facilities. They are easily differentiated from other spaces requiring a static-free environment. For example, people working in EPAs are required to wear special static-control footwear. ...

Why specify different static control parameters for tabletops than flooring?

The advice you were given was correct: Table coverings and flooring materials, because they perform different functions, require different electrical parameters.Table coverings solve CDM (charged device model) problems—that is, they prevent static from building on and discharge static from sensitive electronic parts. The static on sensitive electronics must be discharged slowly—or the rate of discharge could fry the internal circuitry.Static control flooring solves HBM (human body model) problems—it prevents and eliminates static on people, ...

Specifying Static-free Floors: ESD sensitivity and risks for personal safety and electronic equipment

Static electricity discharge (ESD) creates problems for manufacturers and users of electronic equipment. One way to combat ESD is to install static free flooring in environments like data centers and mission critical areas where static discharges can not be tolerated under any circumstances. Unfortunately as much as 50% of static control flooring is specified incorrectly leaving specifiers open to liability and possible safety concerns. Since static control flooring terminology can be confusing, this article provides defintions and explanations of ...

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 ...

Why do you “precision mill” solid vinyl ESD tiles?

Understanding what solid vinyl tile (SVT) is and how it is made will help you understand the advantages of precision milling.SVT has the same color pattern and material composition on both sides of the tile. This is because the color pattern goes through the whole tile to the back. Solid vinyl tiles are just what the term implies, vinyl without any fillers. ESD solid vinyl tile also has the same conductive elements through the full thickness of the ...

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 ...

Don't Let Moisture Ruin Your ESD Flooring Installation

Yesterday I was contacted by a client who wanted my opinion about a small company's new inexpensive system that would eliminate moisture vapor problems in concrete. The client was excited because his facility has a major vapor emission problem in the concrete floor. Measurements using Test Method ASTM F2170 had determined concrete humidity levels in excess of 90% all over the facility. These measurements are quite high; Essentially these numbers equate to a near 100% probability that any ...

How to discuss and recommend the right static control flooring with a client

A guide for architects working within client environments and applications that require conductive flooringI recently visited with an architect who asked me how to best discuss and guide a client interested in using static control carpet in their application and environment.There are two main question areas to begin the client discussion and help determine the right static control flooring recommendation:What is the electronic industry supplier environment? Are they actively handling static sensitive electronic parts and sub-assemblies (as opposed ...

Are You Grounded®? Evaluating Waxed, Solid Dissipative Vinyl Tile vs. Wax-Free, ESD, Conductive Vinyl Tile

Recently we decided to do some spot testing of various “conductive” flooring products in our office in Massachusetts as an exercise to further develop our library of resources available to those who struggle to understand ESD flooring and the underlying principles of static electricity. It is important to note that the day we tested it was very cold outside (and in our office) and that the low relative humidity is the main reason for choosing this particular day ...

Fault-Tolerant Anti Static Flooring

Wikipedia defines “fault tolerant design” or “fail safe design” as “design that enables a system to continue operation, possibly at a reduced level…rather than failing completely”.1Over the years, I have found that this is a very successful way for customers to think about their ESD flooring needs. For most environments, the hazard of static to equipment and/or operations is a risk that cannot be taken. Fault-tolerant ESD flooring is intrinsically ...
