Trial Number 4

Trial Purpose:

To determine temperature dependance

Date Run:

03/08/1996

Experiment Procedure:

The purpose of this trial is to determine the temperature dependance of the two terpene chemistries as compared to NMP.
Three coupons will be cleaned in 500 ml of each solution at each temperature level (75F, 120F, 160F). Cleaning time will be for thirty minutes, and an acetone rinse will follow. All coupons were prepared and contaminated in the same method as previous experiments.
Data for cleaning efficiency at 160F will be imported from Phase II results to avoid redundant testing.

SUBSTRATE MATERIAL: 304 Stainless Steel Coupons
CONTAMINANTS: Durane Base Coatings #51144
CONTAMINATING PROCESS USED: Rubbed on with swab and allowed to cure overnight
