Brittleness Tester, ET 05-II

Elastocon Brittleness Tester, ET 05-II, for automatic determination of Brittleness point according to ISO 812, ISO 974, ASTM D746 and ASTM D2137.

The purchase includes the instrument, a software for the Brittleness test and a computer. The test rig is raised by pneumatic cylinders, which require an air supply of 6 Bar.

The brittleness tester is designed as a falling weight tester, where the speed is set by the height and the energy by the attached weights.

The computer controls the temperature rise and measures the temperature at impact. The result from each stroke is entered by typing the result in the software.

The speed is measured after the impact, to verify the speed loss during impact.

We recommend the automatic cooling system with liquid nitrogen that can be supplied. Another useful option is
the ET 04 freezer for precooling of the cooling media (usually ethanol), during nights or other times when the instrument
is not in use. If the cooling media is pre-cooled, the amount of liquid nitrogen necessary to start the test will decrease remarkably.
