Results of Friction Coefficient Test <br /> March 8,2000 <br /> Russ Engineering Group,Inc. <br /> 7600 GSRI Avenue <br /> Baton Rouge,La. 70820 <br /> Eight(8)base assemblies were tested for coefficient of static friction.The tests were <br /> performed by Professional Service Industries,Inc.in their laboratory in Pittsburgh,Pa. <br /> Three configurations were tested on four different surfaces. <br /> The three assemblies were: <br /> - HDPE Base <br /> - HPDE Base on Rubberized Bearing Pad(Epoxied to the base) <br /> - HPDE Base on Rubberized Bearing Pad(Non-Epoxied) <br /> The four surfaces were: <br /> - Dry Concrete <br /> - Wet Concrete <br /> - Dry Rubber Membrane <br /> - Wet Rubber Membrane <br /> A fifty(50)pound weight was placed on the center of the base assembly.A Chantillon <br /> Digital Force Gauge,Model#DRC 100,was used to pull the base.The horizontal force <br /> required to put the base into motion was then recorded.The coefficient of static friction is <br /> simply the horizontal force in pound divided by 50 pounds. <br /> The results of the above test are tabulated as follows: <br /> HDPE Base <br /> Test No. Surface Condition Force Applied Coefficient of Friction <br /> 1 Dry Concrete 32.2 0.64 <br /> 2 Dry Concrete 30.8 0.62 <br /> 3 Dry Concrete 30.9 0.62 <br /> 4 Dry Concrete 29.1 0.58 <br /> 5 Dry Concrete 29.3 0.59 <br /> Average 30.5 0.61 <br /> HDPE Base/Rubberized Pad(Epoxied) <br /> Test No. Surface Condition Force Applied Coefficient of Friction <br /> 1 Dry Concrete 51.4 1.03 <br /> 2 Dry Concrete 49.8 1.00 <br /> 3 Dry Concrete 50.5 1.01 <br /> 4 Dry Concrete 52.6 1.05 <br /> 5 Dry Concrete 50.6 1.01 <br /> Average 51.0 1.02 <br /> HDPE Base/Rubberized Pad(Non-Epoxied) <br /> Test No. Surface Condition Force Applied Coefficient of Friction <br /> 1 Dry Concrete 37.7 0.75 <br /> 2 Dry Concrete 38.4 0.77 <br /> Advanced Support Products, Inc. page 1 of I <br />
