Ductility Testing Machine By Eie Instruments Private Limited

(As Per IS : 1208 a 1978)
Introduction:
This method is used for determining the ductility of bituminous materials by measuring the elongation before breaking when two ends of a briquette specimen are pulled apart at a speed of 50mm/min + 2.5mm/min at temperature of 270C + 0.50C.
General Description & Specifications:
The Machine consist of the following:
Stainless steel bath
Temperature controller (Thermostatic/Digital)
Immersion electric heater
Constant speed Pump cum stirrer
Carriage holding up to three standard briquette moulds
Electric motor with gear mechanism
Stainless steel scale and pointer
Control Panel
Optional Fittings At Extra Cost:

Digital Temperature indicator cum controller (in place of Thermostatic control)
Digital display for Elongation
The more advanced model with refrigeration system which ensures better temperature control in tropical conditions. The Machine is mounted on a steel stand with refrigeration unit at its base.
Base Plate for mould.
Mould for elastic recovery.
Specifications:
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 both. A pointer fixed to the carrier moves over.
