The TB-1400 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. It is designed for testing 3 specimens simultaneously. The Internal tank is made of stainless steel. The bath is fitted with an immersion heater in order to obtain (in normal conditions), the 25°C test temperature.
Each machine comprises speed control and water circulator to maintain the homogenous water temperature.
TB-1400 and TB-1420 have the same specifications, except that TB-1420 contains an internal cooler. It is not possible to convert TB-1400 to TB-1420.
