ASTM D36 Automatic Bitumen Softening Point of Asphalt (Ring-and-Ball)
KN-36 Apparatus for Softening Point of Asphalt (Ring-and-Ball Test apparatus) conforms to the ASTM D36 Standard Test Method for Softening Point of Bitumen (Ring-and-Ball Apparatus). The apparatus covers the determination of the softening point of bitumen in the range from 30 to 160°C [86 to 320°F] using the ring-and-ball apparatus immersed in distilled water [30 to 80°C] or USP glycerin (above 80 to 160°C).

Automatic Dropping Point, Melting Point and Softening Point Tester
KN-70 Automatic Dropping Point, Melting Point and Softening Point Tester perfectly combines high-precision temperature control technology and high-definition video camera technology, not only to provide users with accurate, stable, and reliable test results, but also to provide users with efficient and convenient test experience. The high-definition video can easily and clearly see the whole process of the sample state change, and the real-time spectrum display is automatically detected, which is convenient for the user to accurately measure the dropping point/softening point of the sample. Standard cups and measurement methods can ensure the accuracy of the results.

ASTM D36 Softening Point Of Bitumen
Two horizontal disks of bitumen, cast in shouldered brass rings, are heated at a controlled rate in a liquid bath while each supports a steel ball. The softening point is reported as the mean of the temperatures at which the two disks soften enough to allow each ball, enveloped in bitumen, to fall a distance of 25 mm (1.0 in.)
