The softening point apparatus is a ring and ball method apparatus used to determine the softening point of asphalts, pitches, tars and most resins. The softening point is the degree of temperature at which a solid substance begins to convert into a liquid state under certain specific conditions.
Characteristics
-
One of the most common ways to determine the softening point is by using a ring and ball apparatus.
-
During this test, steel balls are placed on bitumen disks inside a bath.
-
As the temperature of the bath increases, the samples soften and are unable to retain the beads.
-
The temperature at which the balls drop 25 mm (1 inch) is then recorded.
