Ring-and-ball method (ASTM D36-26). In the United States, two other softening point methods ate employed cube-in-air (35) and cube-in-water (36). Cube-in-air softening point = R-and-B softening point +4 C. Cube-in-water softening point = R-and-B softening point +10 C. 

Trinidad asphalt has a relatively uniform composition of 29% water and gas, 39% bitumen soluble in carbon disulfide, 27% mineral matter on ignition, and 5% bitumen that remains adsorbed on the mineral matter. Refining is essentially a process of dehydration by heating the cmde asphalt to ca 165°C. The refined product averages 36% mineral ash with a penetration at 25°C of about 2 (0.2 mm), a softening point (ring and ball method) of 99°C, a flash point (Cleveland open cup) of 254°C, a sulfur content of 3.3%, and a saponification value of 45 mg KOH/g. The mineral matter typically contains... 

Although not widely used, there are other methods to determine the softening point, such as the capillary method, the flow point, the drop point, and the Kofier method. The different methods provide different values of the softening point. In general, the Ring and Ball method provides the highest softening point while the... 

There are several methods commonly employed to measure the softening point, such as the ring-and-ball method and Durran s mercury methods. These measure the temperature at which the resin reaches an arbitrary softness.
