A Guide to ESD Flooring Selection

Choosing the Right ESD Floor

Staticworx FlooringElectrostatic discharge (ESD) is a well-documented, invisible threat to electronic parts, systems, and mission-critical operations. Risks include damage to equipment, product returns, facility downtime, communication errors, and liability.

Eliminating the risk of random ESD events requires “fault-tolerant” static-control flooring that performs consistently — regardless of variables such as footwear, maintenance, and humidity. Specifications for a static-control floor should address unique environmental conditions and meet the latest industry-approved ESD standards.

Using evidence-based design principles, you can match the right product to its post-installation environment.

Flooring Specification Checklist

Check your environment.

Will the floor be installed in a stringently controlled ESD-protected area (EPA) — mandating special ESD footwear? In an environment where static-control footwear is required but not enforced? Or in an end-user environment with no static-control protocols?

Check to be sure the floor meets industry standards for static-control flooring.

  • Reference ANSI/ESD S20.20 and IEC 61340- 5-1 for electronics manufacturing.
  • Refer to Motorola R56 and ATIS- 0600321 for mission-critical environments — e.g., data centers or 9-1-1 dispatch centers.
  • Use FAA 019f for flight control applications.

Check which types of footwear will be used.

Footwear affects the performance of static-control floors. When evaluating static generation, test every type of footwear that may be used, both standard and static control.

Check body voltage generation.

Find out how much static will be generated when people walk across the floor, using the ANSI/ESD S97.2 charge generation test.

Check static-control terminology.

Pay special attention to terms like conductive; static dissipative; ohms; and static generation. Be aware that certain terms, such as ESD flooring, are generic, so mean very little.

Check conductivity.

Be sure the floor provides a safe path to ground. Find the “sweet spot” for conductivity.

Check for permanent static control.

The anti-static properties of some static-control floors come from the application of special waxes and sprays that wear off and must be continually reapplied.

□ Check durability requirements.

Will the floor be installed in a high- or low-traffic area? Will soldering equipment or solvents be used? Will heavy loads be moved across the floor? Will forklifts be in use?

Check aesthetics.

Will the floor maintain its appearance over time and within its environment?

Check short- and long-term budgets.

Consider the initial investment, maintenance, and repair, as well as total life-cycle costs.

Check ergonomics.

Factor anti-fatigue, sound attenuation, and slip resistance into your decision.

Check the time allotted for installation.

Some products require more extensive floor preparation and certain materials are easier to install than others.

Check the origin of the product.

Floor tiles produced offshore are often die cut and, as a result, have slight dimensional variations, causing unsightly gaps in the seams.

Check the warranty.

Select a manufacturer that warrants ESD performance over the life of the product.

Check the floor after it has been installed.

Request a free flooring audit — with written certification that the floor meets static-control parameters.

ESD Flooring Decision Tree

Footwear and static-control flooring work together to control charge generation. This decision tree can help you find the flooring options that are most compatible with your environment. Recommendations are based on electrical resistance, measured in ohms, and charge generation, measured in volts.

Static-control floors should meet ESD performance standards for both resistance and walking body voltage generation. The information presented in this chart assumes that the floor under consideration meets industry standards for electrical resistance—less than or equal to 1.0 x 10E9. All types of footwear—regular and ESD—affect the performance of a static- control floor. It is therefore recommended that you obtain a report from an independent ESD-flooring laboratory, showing performance results, tested with the subject wearing regular shoes (e.g., with rubber, leather, and/or plastic soles), as well as different types of ESD footwear (e.g., heel straps, toe straps, and static-control shoes).

What is Body Voltage Static Generation

Walking — or the friction that occurs when a foot touches and separates from the floor — generates static. These static charges, called Walking Body Voltage, accumulate on the human body and discharge to the first object the person touches, potentially damaging electronic components or systems.

Walking body voltage tests evaluate the flooring system. Using a charge plate monitor, the test measures static generated when a person walks across the floor, wearing a particular type of footwear — regular shoes, or static-control heel straps, toe straps, or ESD shoes. Because different shoes generate different amounts of static, the test is typically repeated, with the subject wearing various types of regular shoes and static-control footwear.

Electrical resistance tests — which ESD flooring must also pass — evaluate only the floor’s path to ground.

Testing a Floor’s Electrical Resistance

Electrical resistance tests use an ohm meter to predict the speed at which an ESD floor will discharge electricity, allowing the charge to pass from the floor’s surface to ground. If resistance is too low, electrical currents can cut across the floor, posing a safety hazard. If it’s too high, static will discharge too slowly, rendering the floor ineffective.
