For determining the hardness number of mastic asphalt for flooring.

It consists of an internally insulated cabinet to the base of which is fitted a water bath having two taps. The bath is heated by an immersion heater and the temperature is controlled with a thermostat at 350+/- 0.50C. A 6.35 mm dia pin is loaded on the specimen by means of a lever to give 31.7 kg. Weight. A dial gauge 0.01 mm x 25 mm is provided to record the penetration of pin into the specimen.

OVERVIEW

The Ductility Testing Machine is used to determine the ductility of bituminous materials in a briquette mould by measuring the breaking elongation at a constant speed of 50 mm/min.

  • This Ductility Testing Machine is designed to test three specimens simultaneously.
  • The machine consists of a carriage moving over a lead screw. An electric motor driven reduction gear unit ensures smooth constant speed and continuous operation.
  • The entire assembly is mounted with a stainless steel lined water bath completely encased in metal bound hardwood.
  • It is equipped with an electric pump circulator and heater. The temperature is controlled thermostatically.
  • Two rates of travel i.e. 50 mm/min and 10 mm/min are provided. Suitable for operation on 230 V, 50 Hz, Single Phase, A.C. supply.

Ductility Testing Machine is supplied complete with:
VSLIC-B125-I Ductility Mould, with Base Plate 3 Nos.
VSLIC-B125-II Thermometer IP 38° C, Range: 23° C to 27° C



SPECIFICATIONS

For determining the hardness number of mastic asphalt for flooring.

It consists of an internally insulated cabinet to the base of which is fitted a water bath having two taps. The bath is heated by an immersion heater and the temperature is controlled with a thermostat at 350+/- 0.50C. A 6.35 mm dia pin is loaded on the specimen by means of a lever to give 31.7 kg. Weight. A dial gauge 0.01 mm x 25 mm is provided to record the penetration of pin into the specimen.

Application and principle:

Ductility is defined as distance in cms to which a standard briquette of bitumen can be stretched before the thread breaks. The briquette is stretched at a rate of 50 mm/min. ± 2.5mm per minute at a temperature of 25°C ± 0.1°C

Apparatus Description:

The apparatus consists of water bath with a thermostatic heater, and a circulating pump to maintain uniform water temperature. One half of the briquette moulds is fixed in 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 0‑100 cm x 1mm fixed on the bath with “0” (Zero) of the scale towards the fixed plates side. The rotating shaft has 2 speeds of travel for the bracket, 5 cm/min and 1 cm/min ‑ selected by a clutch. Water bath inside is of stainless steel with insulation and water drain cock . A heater with thermostatic control is fitted 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 supply single phase.

Note: Refrigerated ductility testing machine to operate at 27 °C with control accuracy of ± 0.1 °C also available. Price on request. The Ductility Testing Machine can be supplied with Digital Temp. controller for accurate temp. control at extra cost
