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. It is a national floor slip test standard in at least 49 nations. There […]

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 The previously-used ASTM C 1028 friction test method is obsolete, and testing using the AcuTest method in ANSI A137.1 slip test must show a minimum of 0.42 wet dynamic coefficient of friction — but many other factors […]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 […]

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. […]

What’s the Difference Between the Three ANSI standards for floor slip resistance?

The American National Standards Institute (ANSI) has three pedestrian floor friction standards involving tests using the BOT-3000E digital tribometer, intended for testing flooring for indoor use. Why do they have three standards, and what’s the difference between them? They all have different test methods and different minimum coefficient of friction values (0.42, 0.43, and 0.60). […]

Does ANSI Tile Spec A137.1 help protect you from liability for slipping accidents?

If you specify or buy flooring based on a minimum wet dynamic coefficient of friction of 0.42, you may be vulnerable to charges of negligence if a slipping injury occurs on that floor. Here we tell you why, and how to avoid the situation. American National Standards Institute (ANSI) issued its standard A137.1, “Specifications for […]
