Trial Purpose:
To evaluate three additional products on second supplied soil.
Date Run:
05/07/2004Experiment Procedure:
Three products were selected based on success on the fourth supplied contaminant. All were used at full strength in a 250 ml beaker at room temperature. Nine preweighed silver plated copper coupons were coated with the Houghton Chemical Cut-Max 135 (64742-52-5, 64741-96-4) using a hand held swab. Coupons were weighed a second time to determine the amount of soil added to each coupon. Three coupons were cleaned in each solution for 5 minutes using stir-bar agitation. After cleaning parts were weighed a final time and efficiencies were calculated.
Trial Results:
All three products removed over 99% of the oil in five minutes. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon.

Success Rating:
A follow up test, usually based on company input.Conclusion:
The same three products will be tested on the third supplied soil under the same conditions.
