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. ANSI A AMERICAN NATIONAL STANDARD SPECIFICATIONS FOR CERAMIC TILE – VERSION 1. Learn if ANSI Tile Spec A is enough to protect your floors from slipping accidents. Safety Direct America performs slip resistance testing.

A tile with wet DCOF of w137.1 0. If you specify or buy flooring based on a minimum wet dynamic coefficient of friction DCOF of 0. Does this system make more sense than a one-size-fits-all minimum such as 0.

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

That test was not based on scientific slip and fall research either, and the ASTM finally withdrew that test method in There are safety standards for other outdoor areas as well.

How much higher should it be? It does not ensure safety.

C was withdrawn by the ASTM in since it was a very bad test that was basically responsible for thousands upon thousands of needless slip and fall accidents across the country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. 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.

Restrooms in offices and shopping ansu, where people might be moving faster, should have a PTV of 35 or higher. The same instrument, the BOTE, is x137.1 for both tests. 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 many years. Should it be 0. They state that the possibility of a slip may be affected by:.

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. Communal shower rooms should have a minimum wet PTV of 40, and swimming pool ramps and stairs leading into water should have at least Here we tell you why, and how to avoid the situation.

What You Need to Know About the ANSI A137.1/A326.3 Tile Slip Test

Here we tell you why, and how to avoid the situation. Those are typically barefoot areas, but there are also many standards for indoor areas where shoes are worn: 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.

The stated purpose of the Code is to establish minimum requirements. We do this floor slip resistance testing work for commercial buildings, major cruise ship companies, tile vendors, attorneys, and many others. The code requires a minimum wet dynamic coefficient of friction DCOF of 0. The 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 into these safety standards are unparalleled with any other instrument or test method.

There are much more reliable slip resistance test methods available to ascertain what your real-world slip risk will be. 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. If you specify or buy flooring based on a minimum wet dynamic coefficient of friction of 0. This usually results in a lower DCOF for the same tile.


ANSI has a better test for assessing floor slip resistance: Certainly these published lists can expose people on the buying side, and perhaps in the whole chain of supply as well, to accusations of negligence. For more information see SafetyDirectAmerica.

George Sotter at How can people do a better job for themselves and the public than just looking for a minimum DCOF of amsi. And negligence is something that plaintiff lawyers love to see when their client has had an expensive and debilitating injury.

And why should ceramic tile have an advantage or disadvantage over other flooring when setting a safety minimum? The code specifies a minimum wet dynamic coefficient of friction DCOF of 0.

ANSI A – The Tile Council of North America

The specifier shall determine tiles appropriate for specific project conditions, considering by way of example, but not in limitation:. Just as a point of reference, American and European slip resistance test standards require that a basketball court floor ajsi a dry coefficient of friction of 0.

Do you duly consider all of the above 16 listed items when you specify, buy or sell flooring?

So does a wet DCOF rating of 0.
