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.

Does this system make more sense than a one-size-fits-all minimum such as 0. That test was not based on scientific slip and fall research either, and the ASTM finally withdrew that test method in C was withdrawn by the ASTM in since it was a very bad test that was basically responsible for thousands upon thousands of needless slip and fall accidents across the country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 a317.1 various flooring materials.

Do you duly consider all of the above 16 listed items when you specify, buy or sell flooring? Should it be 0. Certainly these published lists can expose people on the q137.1 side, and perhaps in the whole chain of supply as well, to accusations of negligence. Here we tell you why, and how to avoid the situation.

ANSI Tile Spec A – Slip-and-Fall Liability

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. This usually results in a lower DCOF for the same tile. 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.


The code specifies a minimum wet dynamic coefficient of friction DCOF of 0.

How much higher should it be? 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 a1377.1 purchases all over the USA for many years.

ANSI A – The Tile Council of North America

The same instrument, the BOTE, is used for both tests. They state that the possibility of a slip may be affected by:. Communal shower rooms should have a minimum wet PTV of 40, and swimming pool ramps and stairs leading into water should have at least If you specify or buy flooring based on a minimum wet dynamic coefficient of friction DCOF of 0.

And negligence is something that plaintiff lawyers love to see when their client has had an expensive and debilitating injury. ANSI has a better test for assessing floor slip resistance: As such it can provide a17.1 useful comparison of surfaces, but does not predict the likelihood a person will or will not slip on a hard surface flooring material.

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

For more information see SafetyDirectAmerica. Restrooms in offices and shopping centers, where people might be moving faster, should have a PTV of 35 or higher. There are much more reliable slip resistance test methods available to ascertain what your real-world slip risk will be. 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. George Sotter at There are safety standards for other outdoor areas as well.


How can people do a better job for themselves and the public than just looking for a minimum DCOF of 0. A tile with wet DCOF of only 0. If you specify or buy flooring based on a minimum wet dynamic coefficient of friction of 0. 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.

The specifier shall determine tiles appropriate for specific project conditions, considering by way of example, but not in limitation:. The code requires a minimum wet dynamic coefficient of friction DCOF of 0.

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

It does not ensure safety. Here we tell you why, and how to avoid the situation. Those are typically w137.1 areas, but there are also many standards for indoor areas where shoes are worn:
