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.

The code requires a minimum wet dynamic coefficient of friction DCOF of 0. Here we tell you why, and how to avoid the situation. Does this system make more sense than a one-size-fits-all minimum such as 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. Those are typically barefoot areas, but there are also many standards for indoor areas where shoes are worn: George Sotter at There are safety standards for other outdoor areas as well.
New ANSI DCOF Standard Explained – PantheonPantheon
Do you duly consider all of the above 16 listed items when you specify, buy or sell flooring? Anai 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.
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. Certainly these published lists can expose people on snsi buying side, and perhaps in the whole chain of supply as well, to accusations of negligence.
How much higher should it be? C was withdrawn by the ASTM in since it was a very bad test that was basically responsible for thousands upon thousands of needless slip and fall accidents across the country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.
New ANSI 137.1 DCOF Standard Explained
Communal shower rooms should have a minimum wet PTV of 40, and swimming pool ramps and stairs leading into water should ansj at least That higher minimum also goes for bathrooms in hospitals and aged care facilities, because the people involved there are at high risk.
How can people do a better job for themselves and the public than just looking for a minimum DCOF of 0.
For more information see SafetyDirectAmerica. It does not ensure safety.
ANSI Tile Spec A – Slip-and-Fall Liability
So does a wet DCOF rating of 0. A tile with wet DCOF of only 0. Should it be 0.
Just as a point of reference, American and European slip resistance test standards require that a znsi court floor have a dry coefficient of friction of 0. We do this floor slip resistance testing work for commercial buildings, major cruise ship companies, tile vendors, attorneys, and many others.
As such it can provide a useful comparison of surfaces, but does not predict the likelihood a person will or will not anso on a hard surface flooring material.
ANSI has a better test for assessing floor slip resistance: Here we tell you why, and how to avoid the situation.
Does ANSI Tile Spec A137.1 help protect you from liability for slipping accidents?
This usually results in a lower DCOF for the same tile. If you specify or buy flooring based on a minimum wet dynamic coefficient of friction DCOF 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.
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.
The specifier shall determine tiles appropriate for specific project conditions, considering by way of example, but not in limitation:. That test was not based on scientific slip and fall research either, and the ASTM finally withdrew that test method in And why should ceramic tile have an advantage or disadvantage over other flooring when setting a safety minimum? They state that the possibility of a slip may be affected by:.
