A recent global interlaboratory program “Slip Resistance Proficiency Testing — Pendulum Friction Tester,” showed Sotter Engineering Corporation’s Safety Direct America (SDA) floor slip resistance testing laboratory to be one of the world’s most accurate in use of the pendulum skid tester. The pendulum is a national standard for pedestrian floor and tile slip resistance testing … Continue reading “New Study Shows Sotter Engineering to be one of World’s Most Accurate Pendulum Floor Slip Test Labs”

How does ANSI DCOF compare with Pendulum Test Value?
The most recent American National Standards Institute (ANSI) dynamic coefficient of friction (DCOF) test method, ANSI A326.3, states that “hard surface flooring materials suitable for level interior spaces expected to be walked upon when wet with water shall have a wet DCOF of 0.42 or greater when tested … as per this standard.” The older … Continue reading “How does ANSI DCOF compare with Pendulum Test Value?”
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 … Continue reading “ASTM F2508 and the pendulum slip resistance tester”
Test Your New Pool Deck’s Slip Resistance BEFORE Opening the Pool!
It is amazing how often both large and small swimming pool decks are installed with no thought to wet slip resistance until falls, sometimes catastrophic, begin to happen. By the time the first serious slip injury happens, the flooring vendor has usually cashed his check and is unconcerned about the problem. Wet bare feet have … Continue reading “Test Your New Pool Deck’s Slip Resistance BEFORE Opening the Pool!”
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 Although this test is a much better test than the now-withdrawn ASTM C1028 that was previously included in the International Building Code, the new test method comes with a great deal of “disclaimers”, including the warning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 … Continue reading “DCOF Rating for Floors”
A Caveat about Dal-Tile’s Situation-Specific Minimum DCOF AcuTest Values
This blog has previously praised Dal-Tile for recognizing that “one size fits all” does not work when it comes to slip resistance standards (or bikinis, for that matter). For instance, Dal-Tile has recommended a minimum ANSI A137.1 DCOF AcuTest wet dynamic coefficient of friction of 0.60 for swimming pool decks, public showers, and locker rooms. … Continue reading “A Caveat about Dal-Tile’s Situation-Specific Minimum DCOF AcuTest Values”
