What does DCOF mean in tiles?
dynamic coefficient of friction
DCOF, or dynamic coefficient of friction, is a measurement that determines how much friction there is on wet, level floors when walked upon. The results of DCOF testing help us determine the likelihood of whether or not a tile surface could contribute to someone slipping and/or falling.
What is acceptable DCOF?
This standard provides a test method, but also includes discussion about how the wet DCOF value of 0.42 is acceptable as a minimum value for surfaces that are expected to be walked on when wet with water. The standard can be downloaded from the Tile Council of North America.
What does DCOF .42 mean?
According to modern DCOF AcuTest results, receiving higher than a 0.42 DCOF rating on level surfaces means there is a high slip resistance potential and therefore a low probability of slipping.
What is the difference between COF and DCOF?
COF (Coefficient of Friction) is a numeric value that represents the amount of friction between two objects. DCOF (Dynamic Coefficient of Friction) specifically tests the friction of an object that is already in motion (kinetic).
What is DCOF for shower floor?
There is little agreement on what is suitable, but it is normally accepted to have an average Coefficient of Friction rating of . 6 per ASTM C1028 or DCOF minimum of 0.42 per ANSI A137. 1 for wet and dry surfaces.
What is slip coefficient?
The slip coefficient, ks, is defined to be the ratio of the force causing slip at the contact surface to the normal force between the plates resulting from bolt tension.
What should DCOF be for shower floor?
What is the standard for slip resistance?
The most common safety standard for a level floor is a minimum Pendulum Test Value (PTV) of 36. The pendulum is the basis of the Sustainable Slip Resistance standard that has been specified by McDonalds Restaurants since 2006.
What is a good coefficient of friction for bathroom tile?
The Ceramic Tile Institute identifies tile in the following three categories: Slip Resistant: Coefficient of friction is 0.60 or greater (wet). Meets or exceeds general safety and health regulations, ADA and OSHA requirements. Conditionally Slip Resistant: Coefficient of friction is 0.50 to 0.59 (wet).
What is the DCOF required for ADA?
Currently a floor must have a minimum dynamic coefficient of friction (DCOF) between 0.30-0.42 for standard flat flooring, where sloped or ramped surfaces exceeding a 2% slope requires a DCOF between 0.30-0.45. The SEMCO ADA Safety Floor maintains the same dry slip resistance when wet.
What does R10 slip rating mean?
R10 Anti Slip Rating – Options that possess R10 anti slip ratings will provide minor to moderate resistance to slipping, making them ideal for use in hallways, kitchens, and other living spaces including bathrooms.
Can you use large tiles on shower floor?
Yes, it’s entirely possible to use larger size tiles on your bathroom floor. However, you need to ensure your shower pan meets the criteria listed earlier. Make sure you choose a set of tiles that have a COF above 0.6. This rating provides the best grip in the shower to prevent slip-and-falls.
What does DCOF stand for in tile flooring?
WHAT IS DCOF? When it comes to tile and natural stone on the floor, slip-resistance is a main consideration, especially in bathrooms or industrial installations. DCOF, or dynamic coefficient of friction, is a measurement that determines how much friction there is on wet, level floors when walked upon.
What do the results of DCOF testing mean?
The results of DCOF testing help us determine the likelihood of whether or not a tile surface could contribute to someone slipping and/or falling. Then we can recommend the most appropriate tiles with the right slip-resistance for your project.
What kind of DCOF test does safety direct America do?
Safety Direct America can perform both the ANSI A326.3 test and the pendulum DCOF test for you, so you can satisfy building inspector/specifier requests AND assess the real-world slip risk of your flooring samples. We’re the experts in floor slip resistance testing!
What kind of water does DCOF acutest use?
DCOF AcuTest® uses slightly soapy water instead of clean water to recreate environments where slipping occurs. The DCOF AcuTest® has determined that 0.42 wet is the standard for tile that can be used in potentially wet and level applications.
