Ductility Testing Machine

Keeping in mind the vast necessities of the patrons, we are engaged in providing wide range of Cast Iron Ductility Testing Machine.


Other Details:

• With refrigeration system and micro-processor based digital temperature controller
• Ductility is defined as distance in cm 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.± 2.5 mm per minute at a temperature of 27°C ± 0.5°C
• The Machine is having built in refrigeration system to work a below ambient temperature up to 5°C in tropical conditions
• The Machine will operate at 27°C with control accuracy of ± 0.5°C as per the requirement of IS
• The apparatus consists of water bath with a 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 1 mm 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 is fitted inside the water bath
• The Temp is controlled by dual display Microprocessor based Auto Tuning PID Digital Temp
• Indicator cum controller
• 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
• As per IS 1208
