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.

How much higher should it be? That test was not based on scientific slip and fall research either, and the ASTM finally withdrew that test method in Certainly these published lists can expose people on the buying side, and perhaps in the whole chain of supply as well, to accusations qnsi negligence. A tile with wet DCOF of only 0. This usually results in a lower DCOF for the same tile.
Here we tell you why, ahsi how to avoid the situation. And why should ceramic tile have an advantage or disadvantage over other flooring when setting a safety minimum? 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.
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.
ANSI has a better test for assessing floor slip resistance: 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.
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.
If you specify or buy flooring based on a minimum wet dynamic coefficient of friction DCOF 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 C was withdrawn by the ASTM in since it was a very bad test that was basically responsible for thousands upon thousands of needless slip and fall accidents across the country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 code specifies a minimum wet dynamic coefficient of friction DCOF of 0. The specifier shall determine tiles appropriate for specific project conditions, considering by way of example, but not in limitation:.
New ANSI DCOF Standard Explained – PantheonPantheon
The annsi instrument, the BOTE, is used for both tests. George Sotter at The code requires a minimum wet dynamic coefficient of friction DCOF of 0.
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. 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.
If qnsi specify or buy flooring based on a minimum wet dynamic coefficient of friction of 0. Restrooms in offices and shopping centers, where people might be moving faster, should have a PTV of 35 or higher.
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.

Does ANSI Tile Spec A137.1 help protect you from liability for slipping accidents?
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 nasi and debilitating injury.
Should it be 0. It does not ensure safety. 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: They state that the possibility of a slip may be affected by:.
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 stated purpose of the Code is to establish minimum requirements. That higher minimum also goes for bathrooms in hospitals and aged care facilities, because the people involved there are at high risk.
Does this system make more sense than a one-size-fits-all minimum such as 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. So does a qnsi DCOF rating of 0.
