           Attention:  Mr. Ted Meyers
           Regarding:  Physical Testing of Cast Iron Tiles
                       Gaynes Job No. 13505-1    TufTile P.O. 11552

           Dear Mr. Meyers


           Please find below, the procedures and results of the tests that were conducted on a cast iron tile submitted
           and identified by TufTile, Inc.

           TEST PROCEDURE:

           ASTM C1028 Slip Resistance (static coefficient of friction)


           Testing was not conducted in strict accordance with ASTM C1028 procedures.  Typically, the tiles to be
           tested are a smooth hard surface.  The material submitted has a symmetrical pattern of domes covering the
           surface.  The domes are spaced 2" apart (o.c.) and are 0.65" in diameter at the flat top and are raised 0.2"
           above the surface of the tile.  The entire surface including the domes are covered with pointed nubs,
           approximately 0.039" high.  There are 13 nubs on each dome.  See Photo No. 1 for a Close-up of the
           domes and nubs.


           TufTile, Inc. supplied the material to be pulled across the surface of the tile.  That is:  medium strength
           neoprene, plain black rubber (60A durometer), 3/32" thick procured from McMaster-Carr supply
           company.  The neoprene was used for testing as received (no conditioning or pre-treatment).  A 6" x 6"
           piece of neoprene was then attached to a smooth flat hard surfaced pulling plate


           The tile to be tested was secured in a horizontal position.  The pulling plate was placed on top of the tile
           so that the neoprene covered 9 domes.  A 50 lb. weight was placed on top of the pulling plate.  An
           electronic force-measuring instrument was attached to the pulling plate.  The plate was manually pulled in
           a horizontal plane until the plate began to move across the tile surface.  The initial pulling force was
           recorded in each of four pulls (N, S, E & W).  The average pulling force was divided by the total mass
           acting on the neoprene to determine the static coefficient of friction.  The procedure was conducted with
           the tile and neoprene dry and wet with tap water.  See Photo No. 2 for an overview of the test setup.

           TEST RESULTS:


           Dry Static Coefficient of Friction: 0.948                     Wet Static Coefficient of Friction:   1.099
