Ductility Testing Apparatus Ductility is a process defined as distance in cms to which a standard briquette of bitumen is stretched before the thread breaks. Attached briquette is stretched at a rate of 50mm/minute ±25mm per minute at a temperature of 27ºC ± 0.5ºC. Some of the essential features of our products are:
- Consists of a water bath with a thermostatic heater and a circulating pump to maintain uniform water temperature.
- One half of the briquette moulds is fixed on a fixed plate in the water bath, the other half of the briquette mould is fixed to a carrier which slides over a rotating threaded shaft with a clutch
- The motor and gears to rotate the shaft are housed in a cabinet fixed above the other end of the bath
- A pointer fixed to the carrier moves over a scale graduated from 0-110 cm x 1mm fixed on the bath with “0” (zero) of the scale towards the fixed plate side
- The rotating shaft has 2 speeds of travel for the bracket, 5cm/min and 1 cm/min., selected by a clutch. Water bath inside is aluminum, it is an insulated water bath.
- Water bath is provided with a drain.
- A heater with thermostatic control is fixed inside the water bath.
- Control switches for motor, stirrer, heater and indicator lamps are fixed at a convenient place on the water bath, complete with three briquette moulds and one base plate, all made of brass.
- Operates on 230 volts A.C. single phase.
- Accessories: Thermometer IP 38 C, range 23ºC to 27ºC and dDuctility mould with base-plate.
