Force Ductility Testing Machine


The TB-1430 Force Ductility Testing Machine is used to determine the the deformation energy required to stretch a bitumen sample from 200 mm elongation to 400 mm elongation. Force ductility machine is capable of testing 3 specimens simultaneously. The speed of the machine can be adjusted from 5 mm/ min. to 100 mm/ min. Internal tank is made of stainless steel. The bath is fitted with an immersion heater in order to obtain the 25°C test temperature required for normal ductility testing.
Water bath is covered by insulating material to reduce the heat loss during testing.

The machine can be supplied with an external Cooler / Circulator Unit necessary to obtain the 5°C test temperature required for force ductility testing according to EN 13589.

TB-1430 Force Ductility Testing Machine has 3 load cells. The accuracy of load cells are ±0,1N with a maximum capacity of 300 N. Test speed can be adjusted and load-displacement curves can be drawn through the software. Software for TB-1430 is capable of calculating deformation energy according to EN 13589 and displaying force vs displacement graphs for each sample separately or on the same screen.

Cooler/Circulator Unit (TGE-4110), moulds and mould base plates should be ordered separately.
