New Practice for Evaluating Water-Miscible Metalworking Fluid Foaming Tendency by Recirculation testing
1. Scope
This practice addresses the evaluation of the foaming tendency of metal working fluids including persistence over time and foam knockdown tendency using recirculation.Keywords
foam; foaming; metal working; recirculation; foam knockdownRationale
Many foam test methods provide insight into either foam knockdown or initial foaming behavior of a system. These methods do not always simulate the field application for metal working fluids as they are used over extended periods of time. There is a need for a standard test method in which foam control persistence and knockdown are tested with the ability to alter temperature, water hardness, speed, pressure and filtration depending on the application.
