Ada Coefficient Of Friction For Flooring

Slip resistant flooring is an important element of ensuring a public access floor is compliant with ada regulations.

Ada coefficient of friction for flooring.

Listed below are ada compliant requirements for ground and floor surfaces check if your floor or ramp os ada compliant. For decades it was widely believed the americans with disabilities act ada required a static coefficient of friction dry or wet as applicable of 0 60 or higher for level floors and 0 80 for ramps. 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. In fact this was never true and the access board of the u s.

Osha recommends that walking surfaces have a coefficient of friction of 0 5. There is a reliable way to know how slippery floor tile will be under both wet and dry conditions. Changes in level up to 1 4 in 6 mm may be vertical and without edge treatment. This guide explains requirements in the ada standards for floor and ground surfaces.

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. Fpo katelyn simpson laboratory manager tile council of north america when it comes to coefficient of friction cof a measurement that relates to traction and tile. A cof of 0 5 which is based upon studies by the university of michigan and reported in the work surface friction. Acutestsm determines dynamic coefficient of friction dcof with a sophisticated instrument called the bot 3000 a type of tribometer1 specific for flooring applications.

Cof or coefficient of friction slip ratings published by tile manufacturers. There are standards that allow for these differences and safety direct america can supply the test data and safety standards to determine whether a particular flooring is appropriate. Cof slip resistance ratings help you determine if you are buying the right tile for the right location. Firmness stability and slip resistance 302 1 carpet 302 2 openings 302 3 changes in level 303 common questions.

Definitions laboratory and field measurements and a comprehensive bibliography is recommended as a guide to achieve proper slip resistance. Specifiers routinely cite the 0 60 value as a requirement for americans with disabilities act ada compliance which isn t entirely accurate. Department of justice has disavowed any responsibility for this custom. Specifications for floor and ground surfaces address surface characteristics carpeting openings and changes in level.
