Trial Report



Trial Number 7

(Client Number 220, Project Number 1)

Trial Purpose: To evaluate five new products on the fourth supplied soil.

Date Run: 04/30/04

Experiment 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.
