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 […]

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(SCOF) was formerly used to measure the slip resistance of a wet floor in the USA, but the test method (ASTM C1028) was withdrawn by the ASTM in 2014.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 […]
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 Although this test is a much better test than the now-withdrawn ASTM C1028 that was previously included in the International Building Code, the new test method comes with a great deal of “disclaimers”, including the warning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 — […]
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 […]
Floor and Tile Slip Resistance Testing Lab: Fast Turnaround AND Low Prices
Safety Direct America makes a specialty of floor slip resistance (coefficient of friction) testing, offering both fast turnaround times and low prices. Here’s a comparison with our chief competitor, using ANSI A137.1 dynamic coefficient of friction testing (DCOF AcuTest) as an example: Turnaround time Our price […]
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 […]
Proposed Federal Rule for Floor Slip Resistance
The U.S. federal government’s Consumer Product Safety Commission (CPSC) is considering a petition requesting rule making to require that manufacturers of floor coverings, floor coverings with coatings, and treated floor coverings label their products’ slip resistance in accordance with an ANSI/National Floor Safety Institute (NFSI) standard, B101.5. (NFSI, Safety Direct America and others offer for-fee […]
Stop Slips on Cruise Ships!
Since 2008, Safety Direct America has been helping some of the world’s foremost cruise ship companies to prevent slips and falls by helping their designers choose flooring appropriate to the situation (with the correct level of wet coefficient of friction). The work improves safety both on new cruise ships and on ships that are routinely […]
How to Prevent Slips and Falls on a Swimming Pool Deck
Unfortunately, many swimming pool decks are slippery when wet as installed! This can and too often does lead to severe accidents for both children and adults. The deck that was supposed to supply fun for the family, club members, or the public becomes a liability that causes pain, suffering, expensive medical treatment, and income losses. […]
