Trial Report



Trial Number 8

(Client Number 299, Project Number 1)

Trial Purpose: To evaluate products at higher concentrations and longer times on cutting fluid.

Date Run: 05/21/08

Experiment Procedure:
Three products from previous lab testing were used at 20% dilution and one was used at five percent. Preweighed coupons were coated with the supplied cutting fluid (WA wood, 57 F Cutting oil) using a hand held swab and weighed a second time to determine the amount of soil added.

Each cleaner was put in a bowl and three coupons were dunked into the solution at a constant rate for 30 seconds of cleaning. 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.

A second batch of coupons were cleaned for 1 minute following all other procedures. An additional three products were included in the evaluation at 20% dilutions.

Trial Results
The 20% solution at 30 seconds were still ineffective on the grinding fluid. However, the increased cleaning time (1 minute) improved the results of
one of the products removing 70% of the contaminant. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon
cleaned at both time lengths.
