Ada Coefficient Of Friction For Flooring

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.

Ada coefficient of friction for flooring.

Cof slip resistance ratings help you determine if you are buying the right tile for the right location. A reasonable measure of slip resistance is static coefficient of friction cof. In fact this was never true and the access board of the u s. A cof of 0 5 which is based upon studies by the university of michigan and reported in the work surface friction.

Definitions laboratory and field measurements and a comprehensive bibliography is recommended as a guide to achieve proper slip resistance. Astm c1028 coefficient of friction coefficient of friction test cof floor slip resistance standards osha osha slip test scof skid test. 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. Department of justice has disavowed any responsibility for this custom.

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. Firmness stability and slip resistance 302 1 carpet 302 2 openings 302 3 changes in level 303 common questions. Specifications for floor and ground surfaces address surface characteristics carpeting openings and changes in level. Cof or coefficient of friction slip ratings published by tile manufacturers.

There is a reliable way to know how slippery floor tile will be under both wet and dry conditions. 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. Osha recommends that walking surfaces have a coefficient of friction of 0 5. This guide explains requirements in the ada standards for floor and ground surfaces.

Specifiers routinely cite the 0 60 value as a requirement for americans with disabilities act ada compliance which isn t entirely accurate. Changes in level up to 1 4 in 6 mm may be vertical and without edge treatment. Listed below are ada compliant requirements for ground and floor surfaces check if your floor or ramp os ada compliant. Slip resistant flooring is an important element of ensuring a public access floor is compliant with ada regulations.
