Softening Point Apparatus
Article No. 13298
Ring & Ball Softening Pt Apparatus 2Ball
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 starts to convert into a liquid state under certain specific conditions.
Features
- One of the most common ways to determine a softening point is through the use of a ring-and-ball apparatus.
- During this test, steel balls are placed on top of bitumen disks within a bath.
- As the temperature of the bath rises, the samples soften and are unable to hold the balls.
- The temperature at which the balls drop 25mm (1 inch) is then recorded.
Standards
Conforms to ASTM D36, ASTM D2398, ASTM E28, AASHTO T53, AASHTO IP198
