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.
If you specify or buy flooring based on 1137.1 minimum wet dynamic coefficient of friction of 0. Here we tell you why, and how to avoid the situation. 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.
Does ANSI Tile Spec A137.1 help protect you from liability for slipping accidents?
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:. They state that the possibility of a slip may be affected by:. 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.
C was withdrawn by the ASTM in since it was a very bad test that was basically responsible for thousands upon thousands of needless slip and fall accidents across the country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.
What You Need to Know About the ANSI A137.1/A326.3 Tile Slip Test
Do you duly consider all of the above 16 listed items when you specify, buy or sell flooring? 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. And negligence is something that plaintiff lawyers love to see when their client has had an expensive and debilitating injury.
How can people do a better job for themselves and the public than just looking for a minimum DCOF of 0. How much higher should it be? Should it be 137.11. 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.
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. Restrooms in offices and shopping centers, where people might be moving faster, should have a PTV of 35 or higher. That higher minimum snsi goes for bathrooms in hospitals and aged care facilities, because the people involved there are at high risk.
Communal shower rooms should have a minimum wet PTV of 40, and swimming pool ramps and stairs leading into water should have at least Those are typically barefoot areas, but there are also many standards for indoor areas where shoes are worn: There are safety standards for other outdoor areas anxi well.
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, ansl the research into these safety standards are unparalleled with any other instrument or test method. A tile with wet DCOF of only 0.
ANSI has a better test for assessing floor slip resistance: This usually results in a lower DCOF for the same tile. The same instrument, the BOTE, is used for both tests.
