Trial Report



Trial Number 334

(Client Number 153, Project Number 1)

Trial Purpose: Laboratory evaluations of alternative cleaning products

Date Run: 05/27/04

Experiment Procedure:
Each product was used at full strength in a 250 ml beaker and heated to 96 F on a hot plate.
Nine preweighed silver plated copper coupons were coated with the Houghton Chemical Cut-Max 135 (64742-52-5, 64741-96-4) 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 weighed a final time and efficiencies were calculated.
