Trial Report



Trial Number 436

(Client Number 153, Project Number 1)

Trial Purpose: Laboratory evaluations of alternative cleaning products

Date Run: 12/17/07

Experiment Procedure:
Using the laboratories standard operating procedures, several products were evaluated for lubricant removal.

Cleaning: 5 minutes of immersion soak at 130 F with stirbar agitation.
Rinsing: Tap Water
Drying : 30 seconds with air blow off
Contaminant: Lubricant - SYNCOOL
Substrate: 2"x 4"x 0.06" - Aluminium Coupons

Products were based on the compatibility of substrate and removal of foreign substance. Used 5% concentration and heated the samples at 135F. The coupons were immersed in a product for 5 minutes, rinsed for 30 seconds in tap water at 120F and dried in 30 seconds using compressed air is room temperature.

Coupons were coated with used oil. Using a handheld swab and allowed to dry for 144 hours at room temperature. The contaminated coupons were weighed again to determine the amount of soil added. After cleaning process the final weights were recorded, efficiencies were calculated and recorded.
