Trial Purpose:
To evaluate five new products on the fourth supplied soil.
Date Run:
04/30/2004Experiment Procedure:
Five products were selected based on client request for vapor degreasing solvents. Each product was used at full strength in a 250 ml beaker and heated to 96 F on a hot plate. Fifteen preweighed aluminum coupons were coated with the C.P. Hall Co. Plasthall ESO oil (8013-07-8) 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 allowed to sit for 10 minutes for drying at room temperature. The coupons were weighed a final time and efficiencies were calculated.
Trial Results:
All five products removed over 98% of the second soil. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.

Success Rating:
A follow up test, usually based on company input.Conclusion:
Eleven products have been tested on four soils using immersion cleaning. The next step in the evaluation will be to test products via vapor degreasing.
