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.

A tile with wet DCOF of only 0. If you specify or buy flooring based on a minimum ani dynamic coefficient of friction DCOF of 0.
C was 17.1 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. Does this system make more sense than a xnsi minimum such as 0. Anso are typically barefoot areas, but there are also many standards for indoor areas where shoes are worn: How much higher should it be?
They state that the possibility of a slip may be affected by:. The specifier shall determine tiles appropriate for specific project conditions, considering by way of example, but not in limitation:. There are much more reliable slip resistance test methods available to ascertain what your real-world slip risk will be.
Does ANSI Tile Spec A137.1 help protect you from liability for slipping accidents?
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. Here we tell you why, and how to avoid the situation.
That test was not based on scientific slip and fall research either, and the ASTM finally withdrew that test method in How can people do a better job for themselves and the public than just looking for a minimum DCOF of 0.
Should it be 0. Ansu 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.
And negligence is something that plaintiff lawyers love to see when their client has had an expensive and debilitating injury. ANSI and TCNA give no guidance as to how all of these items should factor anxi a higher DCOF or slip resistance, if needed, and most flooring manufacturers give no slip resistance guidelines or recommendations whatsoever.
The same instrument, the BOTE, is used for both tests.
ANSI A Tile Slip Test
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. It does not ensure safety. There are safety standards for other outdoor areas as well. 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 of 0. And why should ceramic tile have an advantage or disadvantage over other flooring when setting a safety minimum?
ANSI Tile Spec A – Slip-and-Fall Liability
Communal shower rooms should have a minimum wet PTV of 40, and swimming pool ramps and stairs leading into water should have at least The code requires a minimum wet dynamic ansk 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. Restrooms in offices and shopping centers, where people might be moving faster, should have a PTV of 35 or higher.
We do this floor slip resistance testing work for commercial buildings, major cruise ship companies, tile vendors, attorneys, and many others. So does a wet DCOF rating of 0. 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.
ANSI has a better test for assessing floor slip resistance: This usually results in a lower DCOF for the same tile. Do you duly consider all of the above 16 listed items when you specify, buy or sell flooring? George Sotter at
