Trial Purpose:
To evaluate an additional five products on the first contaminant
Date Run:
05/07/2004Experiment Procedure:
Five products were selected based on success on the fourth supplied contaminant. All five products were used at full strength in a 250 ml beaker. Two products were heated to 96 F on a hot plate and the three Dow products were used at room temperature. Twenty-seven preweighed silver plated copper coupons were coated with the Exxon Mobil Vacmul 03D (94741-44-2) 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 five products tested on the oil removed over 97% in five minutes. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon.
