Summary
The softening point test instrument is designed and made as per
GB/T4507 Standard Test Method for Softening Point of Bitumen of
national standard of People’s Republic of China, T0608 Softening
Point Test (Ring-and-Ball Apparatus) in the industrial standard of
People’s Republic of China JTG E20-2011 Standard Test Methods for Bitumen and Bituminous
Mixtures for Highway Engineering and ASTM D36 Standard Test Method for Softening of Bitumen
(Ring-and-Ball Apparatus).
The ring and ball apparatus is used to determine softening point of
petroleum asphalt, coal pitch, liquid petroleum asphalt, and
several of asphalts. It can be widely used for asphalt
manufacturing companies, highway and bridge construction companies,
relative colleges and universities, and scientific research
institutes.
I. Main technical features
1. This astm d36 softening point tester adopts microcomputer to
control the test. Automatically stir, linear heating, automatically
get the result and automatically print the test result.
2. The beaker adopts high temperature resisting glass material. The
sizes of steel ring and ball can meet test standards.
3. Small desktop structure. LCD display. Light touch panel. It can
determine four samples at a time. Easy to use and results reliable.
