We’ve all heard the old adage, “Fool me once, shame on you; fool me twice, shame on me.” The Tile Council of North America (TCNA), who reportedly is “in partnership” with at least one of America’s largest tile manufacturers, spent almost two decades promoting the misinformation that the ASTM C1028 static coefficient of friction (SCOF) […]

How to Get The Slip and Fall “Expert” Witness Testimony from an English XL VIT and Brungraber Mark IIIB User Thrown Out of Court
Slip and fall “expert” witnesses in the United States typically use either the English XL Variable Incidence Tribometer (VIT) or the Brungraber Mark IIIB, which is incredibly frightening considering that neither of these two instruments have a published, peer-reviewed test method in any country on earth, and both (the English XL and Brungraber Mark II, […]
ASTM E303-22 Revolutionizes Floor Slip Resistance Testing in the USA
Floor slip resistance tests in the USA have historically been written by the members of the ASTM F13 committee. Comprised mostly of expert “liars for hire” that exclusively work for slip and fall attorneys, and representatives of the flooring industry, these tests have been based on either no science, or very little shady science. The […]
ADA Slip Resistance Requirements
The Americans with Disabilities Act (ADA) requires that floors accessible to disabled persons be “slip-resistant”, but does not define what that means. Apparently it’s up to property owners and the courts to decide. But there is a reliable way of assessing slip resistance that is recognized the world over to help comply with ADA slip […]
Can a Floor be Too Slip Resistant?
As floor slip resistance testing experts with decades of experience, we’re sometimes asked if a floor can be too slip resistant, usually by someone who is trying to sell a flooring that is likely too slippery for a particular application. The answer, put simply, is no. There is no such thing as a floor that’s […]
Cleaning Anti-Slip Floors
After installing a tile or other type of flooring that has great slip resistance, or after applying an anti-slip floor coating with great slip resistance on top of a slippery floor (like SparkleTuff™ Anti-Slip Floor Coating), you’ll find that dragging a dirty mop across the floor may no longer be sufficient to get the floor […]
Slippery Epoxy Garage Floors – SparkleTuff™ Anti-Slip Floor Coating to the Rescue
Our transparent abrasive anti-slip floor coating, SparkleTuff™, has been applied to hundreds of different kinds of floors, and we have yet to find a surface to which it won’t adhere. However, based on the number of frantic phone calls we get, home garage floors that have been newly coated with epoxy (or polyurea or polyaspartic […]
ASTM F2508 and the pendulum slip resistance tester
ASTM F2508 is based on a rigorous scientific study of 11 tribometers (or floor slip resistance test devices) that was held at the University of Southern California Medical Center. The peer-reviewed results were published in 2010 in the Journal of Forensic Sciences. Four tiles were tested with the 11 slip test devices, and later a […]
DCOF Rating for Floors
The latest American slip test for floors is the DCOF rating test method specified in ANSI A326.3. Although this test is a much better test than the now-withdrawn ASTM C1028 that was previously included in the International Building Code, the new test method comes with a great deal of “disclaimers”, including the warning that a […]
Pendulum: The Most Widely Used Slip Resistance Test Worldwide
The pendulum skid tester, known in the U.S. as the “British pendulum” although it was invented at the U.S. National Bureau of Standards, is the most widely used floor slip resistance tester worldwide for measuring the slip resistance of pedestrian surfaces (DCOF rating). It is a national floor slip test standard in at least 50 […]
