TESTING REPORT <br />DATE: 1 November 2007 <br />SUBJECT: Trash carts <br />PRODUCT IDENTIFICATION: Rehrig ROC65 Nestable Bar Universal Cart <br />TEST: LOADING AND UNLOADING (CYCLE TEST) -- SE AUTOMATED <br />TEST DESCRIPTION: The loading and unloading test is designed to approximate the useful <br />life of a cart (10 years) in the actual lifting that is performed when emptying the cart into a semi - <br />automated truck. This test is useful in assessing the overall design (such as the lid fit, handle <br />material and hinge mechanism, wheel assembly strength, etc.) and overall durability. <br />MINIMUM PERFORMANCE STANDARD: ANSI standard Z245.30-1999 requires that after <br />testing the cart should not suffer any damage or permanent deformation such that it cannot be <br />safely used in normal operation. ANSI Z-245.60-1999 establishes dimensional requirements for <br />the cart. <br />TEST PROCEDURE (Meets the requirements of ANSI Z245.30-1999): <br />1. The test is conducted at room temperature. <br />2. A standard ARE semi -automated lifting mechanism is used. This lifter is compatible <br />with all currently used carts. The lifting mechanism is attached to a stationary frame <br />which allows the cart to be emptied and then reloaded on each cycle. <br />3. The cycle time is greater than eight seconds, as required in the standard. <br />4. The cart is loaded with inert material at 3.5 pounds per gallon according to the rated size <br />of the container. The loading material is to occupy at least 70% of the volume of the cart. <br />5. The cart is positioned in front of the lifting mechanism and is then engaged by the lifter <br />and lifted to empty the cart into a bin. The cart is set down onto a concrete surface and is <br />held stationary as it is reloaded by tipping the bin to allow the weights to re-enter the cart. <br />6. Inspections are made whenever any change is noticed and after every 100 lifts. <br />7. Failure is judged to be cracks, holes or other induced defects or deformations in the cart <br />that would prevent the carfs use as a trash cart and be emptied by the automated method. <br />TEST RESULTS: <br />Cycles Comments -on Performangg <br />520 No significant damage <br />SUMMARY: The cart passed the ANSI Z245.30-1999 and Z245.60-1999 standards for <br />rninirn performance.. <br />A.
