Summary
The instrument is designed and made as per GB/T4507 Standard Test Method for Softening Point of Petroleum Asphalt of national standard of People's Republic of China , T0608 Asphalt Softening Point Test (Ring-and-Ball Apparatus) in the Industrial Standard of People's Republic of China JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering and ASTM D36 Standard Test Method for Softening of Bitumen (Ring-and-Ball Apparatus). It is suitable to determine softening point of petroleum asphalt, coal pitch, liquid petroleum asphalt, and various asphalts. It can be widely used for asphalt manufacturing companies, highway and bridge construction companies, relative colleges and universities, and scientific research institutes.
