The drop impact apparatus is specifically designed to test the brittleness of flexible plastic materials when subjected to impact at low temperature. The wood base, rubber pad, and specimen are stacked in order. The specimen is stapled 6mm from the edge of the wood base, and the entire drop impact apparatus is then placed in a low temperature chamber for conditioning. Afterward, the striker is released to strike the specimen, which is then removed to assess the fracture behavior.
