Softening point apparatus for Bitumen
Softening Point Apparatus for Bitumen determines the temperature at which bitumen softens under heat using the Ring and Ball method for accurate quality testing.
Compliance Standard : ASTM D36 – Softening Point of Bitumen (Ring & Ball Apparatus), IS 1205 – Methods for testing tar and bituminous materials, IP 58, ISO 4625, DIN 52011.
Application : The Softening Point Apparatus is used to determine the softening point temperature of bitumen, asphalt, pitch, coal tar, and related materials using the Ring and Ball method. Bitumen & asphalt testing laboratories, Petroleum refineries, Road construction quality control labs, Research & educational institutes.
Product Description : The apparatus consists of a brass ring, steel balls, ball centering guides, glass beaker, ring holder assembly, and a controlled heating bath arrangement mounted on a sturdy stand. The sample is placed in brass rings and heated in a liquid bath at a controlled rate. As the temperature rises, the bitumen softens and allows the steel ball to fall a specified distance. The temperature at that point is recorded as the softening point.
The unit is supplied with the following :
- Electric heater with magnetic stirrer for uniform heating.
