Ductility Tester, Temperature-Controlled

Ductility Tester, Temperature-Controlled

The Ductility Test Apparatus is a precision instrument designed to conduct ductility tests on bituminous materials, measuring the elongation of a binder specimen before failure. During testing, the ends of a molded specimen are pulled apart in a liquid-filled trough at a specified speed and temperature, providing accurate and repeatable results. With the addition of Force Ductility Kits, both tensile strength and ductility of specimens can be measured concurrently, making this a versatile tool for comprehensive binder analysis.

Temperature Control

The ductility tester features an advanced heating and cooling circulator for complete temperature control. Mounted in a stainless steel water bath, the system ensures precise control of test temperatures and can test three standard ductility specimens simultaneously. The heating/cooling fluid circulation system uses an immersion heater and refrigerating unit to digitally regulate temperatures from 5° to 25°C ±0.5° (41° to 77°F ±0.9°). Temperature setpoints are easily programmed through the digital controller/display, and dual safety thermostats are in place to prevent temperature over-runs, ensuring safe and accurate testing conditions at all times.

Operation

Engineered for vibration-free operation, the apparatus features a maximum stroke of 1,500mm and maintains a constant travel speed of 50mm per minute via a direct-drive motor. This ensures consistent and reliable test results across all specimens. The maximum force capacity is 300 ±0.1N (67 ±0.02lbf), and a traveling pointer indicates the exact position of the carriage on a fixed scale, providing easy monitoring throughout the test. The ductility test apparatus is housed in a durable enamel outer steel case, with fiberglass-insulated interior stainless steel walls, ensuring longevity and resistance to harsh laboratory environments.

Please note that ductility briquette molds and base plates are required for testing specimens and are sold separately.
