Analyze & Test

Our team of CERTIFIED auditors and technicians will evaluate the dynamic coefficient of friction (DCOF) of your floors using a state-of-the-art tribometry instrument known as the BOT-3000E

There are 2 types of friction involved in a slip and fall: the static coefficient of friction (SCOF) and the dynamic coefficient of friction (DCOF). The SCOF is the force required for one surface to begin sliding over another. The dynamic coefficient of friction (DCOF) is the force needed to keep a surface in motion sliding over another. When discussing the coefficient of friction (COF) in relation to a slip and fall, the SCOF represents the point at which the slip is first initiated and the DCOF the point at which the initial slip turns into a slide and then an eventual fall. 

In 2012, the American National Standards Institute (ANSI) released the ANSI A137.1 standard which measures DCOF under wet conditions using a water solution containing sodium lauryl sulfate (SLS). Since DCOF values relate better to slips occurring while a person is in motion and are used across the globe, a DCOF threshold requirement has now been added to the ANSI A137.1 standard for ceramic tile. It is now the "gold standard" for measuring COF for ceramic tile, according to the Tile Council of North America (TCNA). Architects and designers specifying tile in areas that are expected to be walked upon when wet are responsible for knowing about the 0.42 DCOF threshold requirement.

Using our BOT-3000E tribometer, our team of professionals will measure the DCOF of your floors to determine if your floors are safe and compliant with OSHA and ANSI standards. If the DCOF measurements meet or exceed the 0.42 threshold, you can have the peace of mind of knowing your pedestrian walkway surfaces are compliant. If these measurements fall below the 0.42 threshold, you can rest assured our team can provide remediation services to bring your walkway surfaces into compliance.
