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(SCOF) was formerly used to measure the slip resistance of a wet floor in the USA, but the test method (ASTM C1028) was withdrawn by the ASTM in 2014.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 […]
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 […]
What’s the Cost of a Slip and Fall on a Commercial Property?
A recent article in Risk & Insurance (May 2018, p. 32) cites some data for costs of slip and fall claims. Claims can result in a sharp increase in insurance premiums. If the property is self-insured, costs can come directly off profit. Falls among adults are the most common cause of traumatic brain injury. Commercial […]
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 […]
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 Although this test is a much better test than the now-withdrawn ASTM C1028 that was previously included in the International Building Code, the new test method comes with a great deal of “disclaimers”, including the warning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 […]
Why We Offer a “Recommended Tile Slip Test Package”
When our clients ask for an ANSI/NFSI A137.1 test we often recommend that they order a pendulum test as well. The pair of floor slip resistance tests is popular, and we offer a discounted price of $477.00 (for lab testing) when they are ordered together. The reason has to do with the A137.1 standard — […]
Dal-Tile Recommends Situation-Specific Minimum DCOF AcuTest Values
We have pointed out before that the ANSI A137.1 “DCOF AcuTest” and ANSI A326.3 minimum recommended wet dynamic coefficient of friction (DCOF rating) for level wet indoor areas of 0.42 is “one size fits all” and does not consider the use of the flooring — upstairs elevator lobby, commercial kitchen, pool deck, etc. The traction […]
America Gets Another Terrible, Horrible, No Good, Very Bad Slip Resistance Guideline
Wet, bare feet are soft and essentially treadless, and on a slippery hard floor can be treacherous — leading to falls that sometimes cause permanent brain damage or worse. It’s crucial to provide slip-resistant surfaces at swimming pools where people (some of them sober) will be walking, playing or running (even against the rules) with […]
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 […]
