NOTE: High coefficients of friction indicate potentially good
traction. The Access Board of the U.S. Department of Justice, the
Ceramic Tile Institute, and the City of
Los Angeles, recommend a minimum
average static coefficient of friction, as assessed using this test
method, of 0.60 for level floors and 0.80 for ramps. Slip resistance
can be affected by floor coatings, contamination, and other maintenance
related procedures. |

Surface Micro-Roughness (Rtm) |
average surface roughness: 20.1 microns. |

|
Surface roughness, when combined with a high coefficient
of friction, improves wet traction on many types of flooring surfaces.
For level floors that occasionally become wet with water in use, a
minimum roughness of 10 microns is recommended for safety. (This does
not apply to some floors that are chemically treated to increase slip
resistance.) |
