Digital Softening point apparatus

Digital Softening Point Apparatus measures the temperature at which bitumen softens using automated heating and digital temperature display for precise results.

Digital Softening point apparatus

Compliance Standard : ASTM D36 / D36M, AASHTO T53, IP 58, 198, IS 1205-1958, NF T 66-008.
Application : Bituminous materials, Petroleum asphalt, coal pitch, and various asphalts, Thermoplastic adhesives, resins, plastics, paraffin wax, rubber, and grease (depending on the specific standard), Evaluating the consistency and temperature susceptibility of bituminous binders used in road construction and other applications.

Product Description : The ring and ball apparatus determines the temperature at which a material (like bitumen) softens enough to allow a steel ball of specific dimensions to fall a required distance under test conditions. The sample is cast into shouldered rings and heated at a controlled rate while under the weight of a steel ball.

Technical Specifications :

Temperature Range:

Typically 30 to 200°C or 30 to 157°C, depending on the model and standard. 

Resolution:

Often 0.1°C for digital models. 

Heating Medium:

Distilled water (for lower temperatures), glycerin, or silicone fluid (for higher temperatures). 

Heating Rate:

Heating rate controlled with energy regulator 

Power Supply:

Commonly 220-240 V, 50/60 Hz. 

Testing Capacity 

2 samples at a time.
