A Review of Standards for Pedestrian Slip Resistance Testing

There are a number of floor slip test methods established by standards-setting organizations that assess pedestrian slip resistance. Here we’ll review the most widely known and current ones. They are distinguished by the devices used in the testing. Terms such as DCOF rating, coefficient of friction, slip coefficient, slip resistance rating, and friction coefficient all […]

New Study Shows Sotter Engineering to be one of World’s Most Accurate Pendulum Floor Slip Test Labs

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 […]

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 Although this test is a much better test than the now-withdrawn ASTM C1028 that was previously included in the International Building Code, the new test method comes with a great deal of “disclaimers”, including the warning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 […]

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 49 […]

COF vs. Pendulum Test Value

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) was calculated decades ago at the U.S. National Bureau of Standards, and can be obtained […]

Article published in The Construction Specifier magazine talks slip resistance

John C. Sotter and George Sotter of Safety Direct America were published in the July issue of The Construction Specifier magazine with an article talking about floor slip resistance and keeping floors safe for pedestrians. The article talks about the latest International Building Code (IBC) requirements for slip resistance, and its limitations as far as […]

New Anti-Slip Floor Design Guidelines Aid in Safe Floor Selection

After consulting with many experts in the USA and abroad, including Safety Direct America, Specialty Architectural Products (SAP) in Toledo, Ohio has distributed four-page design guidelines (Design Guide – Anti-Slip) for floor slip resistance testing. The Slip Resistance Test Guidelines are intended to help building owners, architects, interior designers, specification professionals, and graphic designers, mainly […]

Video Explains IBC Requirements for Floor Slip Resistance

The 2012 International Building Code changed slip resistance requirements for indoor floors that may get wet in use. The previously-used ASTM C 1028 friction test method is obsolete, and testing using the AcuTest method in ANSI A137.1 slip test must show a minimum of 0.42 wet dynamic coefficient of friction — but many other factors […]

Natural Stone with Sustainable Slip Resistance Wet

Flooring that gets high foot traffic and can get wet or greasy in use needs slip resistance (or skid resistance) that stands up well under wear rather than losing its wet slip resistance after a few weeks. McDonalds Restaurants spent years in research and devised a laboratory slip test that assesses how well the wet […]

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 […]
