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.
Ansi a137 1 tile slip test.
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.
November 2012 for updates.
American national standards institute ansi published their current revised a137 1 specifications for ceramic tile in 2017.
The ansi standard has been incorporated as a requirement in section 2103 6 ceramic tile of the 2012 international.
It was removed for the next edition in 2015.
Ansi a137 1 2019 like the 2017 edition it revises describes the normally available sizes and shapes of ceramic tile.
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.
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.
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.
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.
When the object is already in motion it is the dynamic cof dcof.
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.
When the object begins at rest the ratio is the static coefficient of friction.
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.
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.
