Reliable floor slip resistance test devices include the pendulum floor slip resistance tester and the SlipAlert Tribometer (now known as the iAlert), which both measure the dynamic coefficient of friction (DCOF) of floors. In the United States of America, we have in the past (and present) allowed tile manufacturers and people who make their living […]

New Australian Study Shows Sotter Engineering (Safety Direct America) is World’s Top Pendulum Floor Slip Resistance Testing Laboratory
A few years ago Sotter Engineering Corporation’s Safety Direct America (SDA) floor slip resistance testing laboratory participated in a global interlaboratory program that showed SDA to be one of the world’s three most accurate labs in use of the pendulum floor slip resistance tester. The pendulum is a national standard for pedestrian floor and tile […]
The Importance of Reliable Floor Slip Resistance Testing
Floor slip resistance testing is an essential process for ensuring safety in public spaces, workplaces, and homes. It helps to identify the level of slip resistance (or COF) of a floor surface, which is crucial in preventing injuries resulting from avoidable slips and falls. The most common floor slip resistance testing technique around the world […]
America’s Floor Slip Resistance Testing Experts
We’ve tested flooring for the dynamic coefficient of friction (DCOF) and slip resistance all over North America and beyond for around 1,000 individual clients so far as America’s leading independent third-party certified floor friction test lab. We don’t lie in court for slip and fall lawyers (like those who mainly use the Brungraber Mark IIIB, […]
Fool Me Once: The Floor Slip Resistance Testing Misinformation Campaign Fooling the USA
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) […]
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 […]
Pool Deck Slip Standard would Create Jobs for Lawyers and Emergency Room Doctors
A swimming pool deck slip resistance standard is proposed that if adopted will cause hundreds of millions of dollars of misspent investment; lead to thousands of slip and fall accidents, many with life-changing injuries; cost hundreds of millions in medical bills and other losses; and lead to far too many premature deaths due to injuries […]
2022 Revised ANSI A326.3 Has Five Situation-Specific DCOF Minimums — And Crucial Caveats
In February of 2022, the American National Standards Institute (ANSI) issued a revised version of their “Test Method for Measuring Dynamic Coefficient of Friction of Hard Surface Flooring Materials.” The test method is called ANSI A326.3, and it sets a very low bar for DCOF in various flooring areas. Slip and fall accidents will likely […]
Floor Slip Rating: SCOF vs. DCOF
Static coefficient of friction (SCOF) was formerly used to measure the slip resistance of a wet floor in the USA, but the test method (ASTM C1028) was withdrawn by the ASTM in 2014. Experts in the USA now know to use dynamic coefficient of friction (DCOF), as the rest of the world has been using […]
ANSI A326.3 Acutest Does Not Predict Likelihood of Slip
A widely used floor friction test, American National Standards Institute A326.3, states in its introduction that “it can provide a useful comparison of surfaces, but it does not predict the likelihood a person will or will not slip on a hard surface flooring material.” The test assesses wet dynamic coefficient of friction (DCOF) using the […]
