ANSI 137.1 PDF

ANSI Dynamic Coefficient of Friction (DCOF) STANDARD. After years research, the tile industry has now passed a new standard for. Learn if ANSI Tile Spec A is enough to protect your floors from slipping accidents. Safety Direct America performs slip resistance testing. ANSI A has always specified ASTM C for coefficient of friction test results. • There has never been a requirement in ANSI or any other governing body.

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

New ANSI 137.1 DCOF Standard Explained

The stated purpose of the Code is to establish minimum requirements. 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. How can people do a better job for themselves and the public than just looking for a minimum 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. For more information see SafetyDirectAmerica.

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. Communal shower rooms should have a minimum wet PTV of 40, and swimming pool ramps and stairs leading into water should have at least A tile with wet DCOF of only 0.


Do you duly consider all of the above 16 listed items when you specify, buy or sell flooring? Those are typically barefoot areas, but there are also many standards for indoor areas where shoes are worn: ANSI has a better test for assessing floor slip resistance: There are much more reliable slip resistance test methods available to ascertain what your real-world slip risk will be.

The same instrument, the BOTE, is used for both tests. Restrooms in offices and shopping centers, where people might be moving faster, should have a PTV of 35 or higher. So does a wet DCOF rating of 0. Certainly these published anwi can expose people on the buying side, and perhaps in the whole chain of supply as well, to accusations of negligence. 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 anso resistance guidelines or recommendations whatsoever.

George Sotter at The code specifies a minimum wet dynamic coefficient of friction DCOF of 0. If you specify or buy flooring based on a minimum wet dynamic coefficient of friction of 0. And why should ceramic tile 137.11 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.

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 specifier shall determine tiles appropriate for specific project conditions, considering by way of example, but not in limitation:.


This usually results in a lower DCOF for the same tile. That higher minimum also goes for bathrooms in hospitals and aged care facilities, because the people involved there are at high risk. Should it be 0.

It does not ensure safety. They state that the possibility of a slip may be affected by:. We do this floor slip resistance testing work for commercial buildings, major cruise ship companies, tile vendors, attorneys, and many others. That test was not based on scientific slip and fall research either, and the ASTM finally withdrew ansii test method in Here we tell you why, ansu how to avoid the situation.

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

ANSI A Tile Slip Test

How much higher should it be? There are safety standards for other outdoor areas as well. And negligence is something that plaintiff lawyers love to see when their client has had an expensive and debilitating injury.
