Trial Report



Trial Number 1

(Client Number 220, Project Number 1)

Trial Purpose: To evaluate selected cleaners on second supplied contaminant

Date Run: 04/16/04

Experiment Procedure:
Six 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.
Eighteen preweighed aluminum coupons were coated with the Cargill, Inc Canola Oil (120962-03-0) 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
Two of the six products were successful in removing over 85% of the soil in five minutes of immersion. Many of the coupons were found to have residual
oil on the back side of the coupons. This resulted when coupons were removed from the beakers (dragging through accumulated oil on the surface). The
table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.

Success Rating
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.

Conclusion
The same products will be tested on the third supplied oil under the same conditions.
