The ANSI A standard applies only to ceramic tile in the Code, but we know of no reason why the safety standard for ceramic tile should be different from.

If you specify or buy flooring based on a minimum wet dynamic coefficient of friction amsi 0. The same instrument, the BOTE, is used for both tests. The standard, which includes a slip resistance test procedure also known as the AcuTest, is incorporated by reference in the International Building Codeused throughout the United States and in several other countries. There are much more reliable slip resistance test methods available to ascertain what your real-world slip risk will be.

They state that the possibility of a slip may be affected by:. Do you duly consider all of the above 16 listed items when you specify, buy or sell flooring? The code specifies a minimum wet dynamic coefficient of friction Nasi of 0.

ANSI A – The Tile Council of North America

And negligence is something that plaintiff lawyers love to see when their client has had an expensive and debilitating injury. Here we tell you why, and how to avoid the situation. How can people do a better job for themselves and the public than just looking for a minimum DCOF of 0.


We do this floor slip resistance testing work for commercial buildings, major cruise ship companies, tile vendors, attorneys, and many others. For instance, a hotel bathroom should have a minimum wet PTV of 20 measured using a soft rubber slider to simulate bare feet or soft shoe bottoms. Those are typically barefoot areas, but there are also many standards for indoor areas where shoes are worn: ANSI and TCNA give no guidance as to how all of these items should factor into a higher DCOF or slip resistance, if needed, and most flooring manufacturers give no slip resistance guidelines or recommendations whatsoever.

That higher minimum also goes for bathrooms in hospitals and ani care facilities, because the people involved there are at high risk.

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

Should it be 0. A tile with wet DCOF of only 0. Does this system make more sense than a one-size-fits-all minimum such as 0.

The stated purpose of the Code is to establish minimum requirements. As such it can provide a useful comparison of surfaces, but does not predict the likelihood a person will or will not slip on a hard surface flooring material. Communal shower rooms should have a minimum wet PTV of 40, and swimming pool ramps and stairs leading into water ans have at least Restrooms in offices and shopping centers, where people might be moving faster, should have a PTV of 35 or higher.

The code requires a minimum wet dynamic coefficient of friction DCOF of 0. It is no longer a current test method and there are, thankfully, no plans to ever resurrect that very poor test method that has been causing slip and fall accidents and billions in ill-advised flooring purchases all over the USA for a1337.1 years.


Here we tell you why, and how to avoid the situation.

Anei pendulum test instrument used in this situation-specific test has been testing floors involved in actual real-world slip and fall accidents in the United Kingdom since the s, so the research anso these safety standards are unparalleled with any other instrument or test method.

C was withdrawn by the ASTM in since it was a very bad test that a1371. basically responsible for thousands upon thousands of needless slip and fall accidents across the country annually by spreading misinformation about the actual real-world slip resistance of various flooring materials. George Sotter at For more information see SafetyDirectAmerica. And why should ceramic tile have an advantage or disadvantage over other flooring when setting a safety minimum?

Just as a point of reference, American and European slip resistance test standards require that a basketball court floor have a dry coefficient of friction of 0.

ANSI A Tile Slip Test

If you specify or buy flooring based on a minimum wet dynamic coefficient of friction DCOF of 0. How much higher should it be? It does not ensure safety. There are safety standards for other outdoor areas as well.

Certainly these published lists can expose people on the buying side, and perhaps in the whole a1377.1 of supply as well, to accusations of negligence.
