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 … Continue reading “ANSI A326.3 Acutest Does Not Predict Likelihood of Slip”

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?”
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 … Continue reading “What’s the Cost of a Slip and Fall on a Commercial Property?”
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 Although this test is a much better test than the now-withdrawn ASTM C1028 that was previously included in the International Building Code, the new test method comes with a great deal of “disclaimers”, including the warning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”
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 — … Continue reading “Why We Offer a “Recommended Tile Slip Test Package””
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 … Continue reading “Dal-Tile Recommends Situation-Specific Minimum DCOF AcuTest Values”
ANSI Issuing Another Standard Slip Test Method for Flooring Materials
The American National Standards Institute (ANSI) is issuing a new test method, with minimum dynamic coefficient of friction (DCOF rating), for slip resistance of hard flooring materials, wet or dry, laboratory or field testing. No minimum DCOF is provided for exterior applications. The BOT-3000E digital tribometer is used for the testing. The Secretariat for the … Continue reading “ANSI Issuing Another Standard Slip Test Method for Flooring Materials”

Slip Resistance of Floor Graphics
The September/October 2016 edition of SGIA Journal (Special Graphic Imaging Association), pp 89–92 has an article, “New Slip Resistance Specifications — Are You in Compliance?”, by the Marketing Manager of Mactac Distributor Products (“Technology that Sticks”, including indoor and outdoor floor graphics). He discusses the following about American National Standards Institute (ANSI) Standard B101.3:   … Continue reading “Slip Resistance of Floor Graphics”
COF vs. Pendulum Test Value (PTV to DCOF conversion table)
Pendulum slip (or skid) resistance data are usually expressed as PTV, Pendulum Test Value (or sometimes BPN, British Pendulum Number, or even SRV, Slip Resistance Value). The question has been asked, “What’s the coefficient of friction?” This number (dynamic COF – DCOF) was calculated decades ago at the U.S. National Bureau of Standards, and can … Continue reading “COF vs. Pendulum Test Value (PTV to DCOF conversion table)”
