ANSI A137.1 slip resistance using BOT-3000E digital slip meter Client: Unicorn Tile Report date: 8/8/14 Flooring: Neo Series matte finish Pieces tested: 3 Size: 12” x 24” Page 1 of 1 Test no.: 1408-0811 Date tested: 8/8/14 Test temperature: 82°F Relative humidity 54% Sensor material: SBR hard rubber Calibration due date of BOT-3000E: 4/16/15 BOT verification: 8/8/14, 17:15 SLS water strength: 0.05% Sensor verification DCOF dry 0.67 (range: 0.67-0.73 before test) ANSI A137.1 Dynamic Coefficient of Friction Test The American National Standards Institute (ANSI) published the A 137.1 American National Standard test for measuring dynamic coefficient of friction (DCOF) of common hard-surface floor materials in 2012. This test is specified by the 2012 International Building Code — see below. The test is wet only but has been modified here for dry testing. Average Dynamic Coefficient of Friction, as received, with SBR hard rubber slider:

DRY 0.54 WET 0.49

Individual test values dry: 0.55, 0.56, 0.58, 0.56; 0.49, 0.51, 0.59, 0.57; 0.50, 0.51, 0.54, 0.49

Wet: 0.50, 0.53, 0.45, 0.49; 0.51, 0.51, 0.47, 0.48; 0.47, 0.46, 0.48, 0.53 Results apply only to the sample tested and at the time of testing. The Americans with Disabilities Act (ADA) requires that accessible floors be “slip-resistant,” but does not define what that means (see www.C1028.info). ANSI A137.1, Section 6.2.2.1.10, states, “Unless otherwise specified, tiles suitable for level interior spaces expected to be walked upon when wet shall have a wet DCOF of 0.42 or greater …” Ramps and exterior surfaces will require higher minimum wet DCOF. For exterior surfaces we suggest a different test and safety standards set forth by ANSI B101.3, or an alternative, the pendulum test and safety standards endorsed by Ceramic Tile Institute of America (ctioa.org). For dry tests we expect that the same safety standard would apply as for wet tests.

Test method The BOT-3000E digital tribometer (friction meter) used for these tests is approved for use in American National Standards Institute (ANSI) Standard A137.1–2012, Section 9.6, “Procedure for Dynamic Coefficient of Friction (DCOF) Testing”. The International Code Council 2012 International Building Code, Section 2103.6 Ceramic tile, states, “Ceramic tile shall be as defined in, and shall conform to the requirements of, ANSI A137.1” The BOT-3000E is fitted with curved, 1-1/8” wide SBR hard artificial rubber contact (slider or test foot) material. Dynamic tests are conducted (if feasible) in four directions. The BOT-3000 is capable of measuring individual (not average) COF values up to 1.00. Thus, any measured value at or near 1.00 may in fact be higher than 1.00. Respectfully submitted, SOTTER ENGINEERING CORPORATION
