When the object is already in motion it is the dynamic cof dcof.
Ansi a137 1 tile slip test.
This ansi standard was incorporated as a requirement in section 2103 6 ceramic tile of the 2012 international building code published by the international code council.
American national standards institute ansi published their current revised a137 1 specifications for ceramic tile in 2017.
It was removed for the next edition in 2015.
This test is primarily a wet test where a 0 42 dcof rating or greater is considered the minimum for level indoor floors that are expected to get wet in use.
Ansi a137 1 american national standard specifications for ceramic tile 2012 section 6 2 2 1 10 coefficient of friction specification section 9 6 procedure for dynamic coefficient of friction dcof testing release date.
Ansi a137 1 2019 like the 2017 edition it revises describes the normally available sizes and shapes of ceramic tile.
The standard which includes a slip resistance test procedure also known as the acutest is incorporated by reference in the 2012 international building code used throughout the united states and in several other countries.
The ansi standard has been incorporated as a requirement in section 2103 6 ceramic tile of the 2012 international.
The ansi a326 3 tile slip test uses the exact same test method but adds more disclaimers and describes the method for testing in the field as a137 1 was intended only as a lab test.
Ansi a137 1 coefficient of friction cof describes the ratio f w between the force necessary to cause an object to slide across a surface and the weight of the object.
Ansi american national standards institute published the ansi a137 1 2012 american national standard test for measuring dynamic coefficient of friction dcof of common hard surface indoor level flooring materials in 2012.
When the object begins at rest the ratio is the static coefficient of friction.
Bot 3000e used in ansi a326 3 and a137 1 in extensive studies at germany s university of wuppertal the bot 3000e was shown to correlate well with human traction when the concentration of the wetting agent was 0 10 percent.
This american national standard covers a breadth of information including the basis for acceptance and testing methods prior to installation marking and certification of ceramic tile definitions of relevant terms and physical properties of standard grade ceramic tile second grade ceramic tile decorative tile and specialty tile.
The american national standards institute ansi published the a137 1 2012 american national standard test for measuring dynamic coefficient of friction dcof of common hard surface indoor level floor materials in 2012.
In 2018 ansi released the a326 3 dcof rating slip test which uses the same test method and was intended to update and replace a137 1.
