Ring & Ball Softening Pt Apparatus 2Ball

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.
