WebFor this reason, the determination of 'softening point' must be made by a fixed, arbitrary and closely defined method if results are to be comparable. Being very simple in concept and equipment, the Ring-and-Ball Test has remained a valuable consistency test for control in refining operations, particularly in the production of air-blown bitumens. Websoftening point Bitumens are viscoelastic materials without sharply defined melting points; they gradually become softer and less viscous as the temperature rises. The softening …
