Impact and Tearing Tester

The impact tester with dart drop weight DIT-01 tests the impact strength and failure limit of material samples made of plastic, aluminium and composite foils, sheets, paper and cardboard with a thickness of <1mm. A ball test is available as well.

The FPP-01 pendulum impact tester measures the impact strength of various materials such as plastic films, paper or cardboard.

The FTS-01, also called the Elmendorf tester, tests the tear strength of foils, paper or similar flat materials.
