Trial Report



Trial Number 6

(Client Number 299, Project Number 1)

Trial Purpose: To evaluate additional products on third supplied metal working fluid

Date Run: 05/20/08

Experiment Procedure:
Preweighed coupons were coated with the supplied rust preventative (WA Wood FPS Rustnot) coating using a hand held swab and weighed a second time to determine the amount of soil added.

Three cleaners from the previous trial and three newly selected products were put in a bowl and three coupons were dunked into the solution at a constant rate for 30 seconds of cleaning. Products were diluted to 20% except for one (Bio T 300B). The coupons were then put on a tray and when done and allowed to air dry. There was no rinse. The process was done to as closely replicate the process used on site as possible. Once dry, final weights were recorded and efficiency calculated for each coupon cleaned.

Trial Results
All six products were fairly successful, removing more than 68% of the rust preventative from the aluminum coupons in 30 seconds of agitation. The
table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
