Cart Test Procedures <br />Otto Environmental Systems manufactures carts that are of the highest quality and <br />durability possible. One way we accomplish this is through a series of tests that <br />simulate the "true to life" abuses to which carts are subjected week after week. <br />Otto's performance testing requirements were designed to simulate the effects of hard <br />use in waste collection field conditions. The severity of some tests was scaled to <br />anticipate an expected 10-year minimum life of the containers. <br />Test Description <br />1. Loaded Cart Drop Test <br />2. Wheel Durability <br />3. Axle Strength Test <br />4. Bottom Wear (Abraision Resistance) <br />5. Wind Resistance <br />6. Loading & Unloading <br />Performance Requirments <br />Five (5) drops with 300 lbs. load from 12 ft. <br />with no damage. <br />520 drops with no failure of wheels <br />800 Lbs. without permanent deformation <br />of axle. <br />100 lbs. load dragged for 9,500 feet without <br />wear -through or leakage. <br />40 mph for 30 seconds from any direction <br />without blowing over. <br />520 complete cycles without any failures <br />In addition, ANSI outlines the following test proceedures in the guidelines set down for <br />refuse collection containers (Z245.30-1999): <br />Slope Stability Test (Appendex B) <br />Durability During Pulling (Appendex C) <br />Loading & Unloading (Appendex D) <br />Center of Balance (Appendex E) <br />Force to Tip (Appendex F) <br />Lid Test (Appendex G) <br />Cart is stable on 5 degree slope <br />See # 2 above. <br />See # 6 above. <br />Balance position achieved with handle <br />positioned 29" (min) to 40" (max) from <br />ground. <br />Maximum force to tip of 120 lbs. <br />Lid withstands 80 lbs. force. <br />
