Elite lab is manufacturer and supplier of Ring and Ball Apparatus in Kolkata, Patna, Ranchi, West Bengal, Bihar and Jharkhand in India. The softening point of asphalt, bitumen, and coal tar determined using the ring and ball test. The softening point of various bituminous materials is assessed using this test, which contains of brass rings and two steel balls.

Bitumen, Asphalt, and Coal Tar's Softening Point

The temperature at which bitumen or tar begins to soften is known as the softening point. ASTM E28-67, ASTM D6493-11 or ASTM D36, specify the temperature in degree oC at which the ball goes through a sample of bitumen and falls through 2.5 cm of bitumen in a mould when heated under water or glycerine under specific conditions of test. Before being used on a road, a binder must be sufficiently fluid.

What are the applications and Accessories of Softening Point?

Calculating a bitumen binder's softening point helps identify the ideal temperature for heating it for various road uses. A ring and ball gadget is used to determine the softening point.

• The Softening Point Testing Apparatus.
• There are two parts to this: a ring and a ball
• Steel balls with a diameter of 9.5 mm and a mass of 3.5 0.05 g apiece.
• Hot Plate with temperature controller.
• Electrically operated stirrer.

6.4 mm-thick brass rings with two numbers on each. There is a 15.9mm and 17.5mm diameter at the bottom and top of the internal diameter, respectively.

To control the movement of steel balls centrally, ball guides are needed Rings may be held in place and a thermometer can be suspended with the aid of this support. There is a 25mm gap between the rings and the top surface of the bottom plate.

Results

The temperature at which binders have the same viscosity is known as the softening point. There is no melting point for bituminous materials. Instead, across a wide range of temperatures, the condition changes from solid to liquid gradually. Materials of Ring and Ball Apparatus Suppliers used as joint and crack fillers must have a high softening point. The advanced the softening point, the less likely they are to flow. The lower the temperature sensitivity, the advanced the softening point. In hotter climates, bitumen with a higher softening point is preferred.

The handle on the PT100 drip tray and probe holder provided by Ring and Ball Apparatus Exporter Kolkata India. makes it easier to insert beakers in specimen holders.

Listed below are our recommendations for three different ways to use hot plates:

10-D1402/D 1500 W standard hot plate with a diameter of 185 mm More affordable option in accordance with ASTM standards.

81-B0145/C1 Hot plate for 81-B0145 Ring and Ball Apparatus in Bihar, Jharkhand, West Bengal, Kolkata, Ranchi, Patnawith centering/protection device. Better suited to a business setting.

10-B0145/E Water churning is required for improved temperature consistency in accordance with either ASTM or EN 1427 Standards.
