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 $387.00 (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) 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 demands […]

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

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 (COF) standard, for slip resistance of hard flooring materials, wet or dry, laboratory or field testing. No minimum COF is provided for exterior applications. The BOT-3000E digital tribometer is approved for testing. The Secretariat for the new […]

Fixing Your Slippery Epoxy Floor

We are continually amazed at how often contractors will install an epoxy floor coating with little or no effort to make it slip-resistant under its known conditions of use — namely, sometimes wet and/or greasy. This happens in commercial, industrial, and household situations. Sometimes there’s no abrasive added to help with wet slip resistance. Other […]

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 […]

Top 10 Ways of Preventing Slips

Here’s a countdown of some of the most simple and cost-effective ways of stopping slip and fall accidents. 10. Post warnings when and where appropriate. 9. Use solings appropriate to the situation. 8. Chemically etch or grind concrete if it’s too smooth. 7. Make sure stairs comply with your local building code, and that nosings […]

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 […]
