Trial Purpose:
To evaluate selected cleaner at a lower concentration.
Date Run:
06/06/2001Experiment Procedure:
One cleaner, selected by the client based on the previous trials was diluted to 1% using DI water and placed in a VWR Scientific Products Aquasonic 150 HT ultrasonic tank and degassed for 5 minutes. One part was analyzed prior to cleaning to determine a baseline level. The part was then cleaned in this solution for 5 minutes at room temperature. Following cleaning, the part was rinsed for 2 minutes using a Crest 40 kHz ultrasonic tank model 4Ht 1014-6 with DI water at room temperature and then dried for 30 minutes at 160 F. After the part cools to room temperature, a final microscopy analysis was performed.
Trial Results:
After analysis, the part looked clean along the seam. There was no major alteration of the surface. Pictures were taken of the part before and after.
Success Rating:
A follow up test, usually based on company input.Conclusion:
Cleaning the supplied part with Tower 270 at 1%, 68 F for 5 minutes appears to have been effective.
