Basic cleaning performance testing was conducted using ASTM G122 as the bases for cleaning.
Cleaning: 5 min. immersion cleaning with air sparger as an agitation medium at 120 F.
Rinsing: 1/2 min. manual with water at 120 F.
Drying :1 min. with heat gun at 500 F.
Contaminant:
1. Grease: keystone KSL-111.ELF Lubricant, Diester based Grease
2. Lubricant - ITW Devkon Safetap stick, grinding lubricant, contains TSRK 80100221-5000P, TSRK 80100221-5001P, TSRK 80100221-5002P
1st 3 evaluations are for comparing stir-bar agitation with air sparger. It was found that first two evaluations, the results were almost comparable but in the third one with Watson formula 7300, air sparger was more affective, about 12% more efficiency.
