Tile Coefficient Of Friction

Specifiers routinely cite the 0 60 value as a requirement for americans with disabilities act ada compliance which isn t entirely accurate.

Tile coefficient of friction.

0 7 and it will be similar for the marble with a polished finish. Dcof or dynamic coefficient of friction is a measurement that determines how much friction there is on wet level floors when walked upon. Astm c 1028 is the standard test method for determining the static coefficient of friction scof of ceramic tile and other like surfaces by the dynamometer pull meter method. Astm c1028 has been withdrawn as of 2 1 14 with no replacement.

Dynamic coefficient of friction dcof ratings help designers architects and builders make more informed choices on tile flooring. Friction is the innate force that resists the sliding motion of one surface against another such as the motion of a foot against a tile floor. What you need to know about the ansi a137 1 a326 3 tile slip test if you specify or buy flooring based on a minimum wet dynamic coefficient of friction dcof of 0 42 referred to in the 2012 international building code ibc you may be vulnerable to charges of negligence if a slipping injury occurs on that floor. The commonly specified and often misunderstood value of 0 60 static coefficient of friction scof determined by the astm c1028 test method has been superseded by a new method new test conditions and a new threshold value all of which can be found in the 2012.

Until now the value of 0 60 static coefficient of friction scof as determined by the astm c1028 test method has been the most commonly specified and often misunderstood standard for ceramic tile. Cof slip resistance ratings help you determine if you are buying the right tile for the right location. There is a reliable way to know how slippery floor tile will be under both wet and dry conditions. This test method covered the measurement of static coefficient of friction scof of ceramic tile or other surfaces under both wet.

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. Cof or coefficient of friction slip ratings published by tile manufacturers. You can also look into a type of sealant that adds extra grip to the surface. Coefficient of friction the tile council of north america dynamic coefficient of friction dcof of hard surface flooring materials since 2012 the ceramic tile industry standard for testing dynamic coefficient of friction dcof has been the dcof acutest.

When it comes to tile and natural stone on the floor slip resistance is a main consideration especially in bathrooms or industrial installations. A polished porcelain tile will have a coefficient of friction of about wet.
