Ductility Testing Machine

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 27°C ± 2°C. 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 from 5° to 30°C. The Machine is having built in refrigeration system to work a below ambient temperature up to 10°C in tropical conditions. The Machine will operate at 27°C with control accuracy of ± 0.5°C as per the requirement of IS.
