What Is the Ring And Ball Apparatus (Electrical) Used For?
Softening point gives a simple measure of the temperature at which bitumen changes from a semi-solid towards a liquid, and it is one of the standard grading tests for paving and industrial binders. The tapered rings are filled with the bitumen sample, set in the ring holder with a 9.5 mm ball on each, and placed in the glass bath; the energy regulator is then set so that the heater raises the bath temperature steadily. The thermometer in the bath is read when each ball, wrapped in softened bitumen, drops to the bottom, and the mean of the two rings is reported. The standards listed are ASTM D36, AASHTO T 53 and BS 2000.
What to Specify When Ordering
- Quantity — the number of apparatus required.
- Thermometer — the IP 60C thermometer (-2 °C to 80 °C) listed as an essential accessory.
Frequently Asked Questions
How is the bath heated on the electrical model?
It has electrical heating through a heater and energy regulator, so the bath temperature can be raised at a controlled rate from a 230 V, 50 Hz, single phase A.C. supply.
What comes with each unit?
Each unit is supplied with a bath of heat resistant glass, 2 Nos. tapered rings, 2 Nos. steel balls of 9.5 mm dia and 1 ring holder.
Which thermometer is needed?
An IP 60C thermometer, range -2 °C to 80 °C, is listed as an essential accessory, together with a 30 °C to 200 °C range.
Why are two rings tested at once?
Two rings and two balls are run together in the same bath so that the result can be taken as the mean of a pair of determinations.
Which standards apply?
The standards listed are ASTM D36, AASHTO T 53 and BS 2000, under which the softening point of bitumen is found by the ring and ball method.
