ASTM D256 - 10

The ASTM D256 documents the test of impact pendulum that consists of examining the impact resistance of plastic material subjected to instantaneous force. The technique is used to gauge the energy consumed in the fracture of a notched specimen and to compare material toughness, brittleness, and endurance in industries. This test is widely used in packaging, automotive, electrical, polymer, and consumer product industries for material selection and quality checks. Presto Laboratories offers advanced Izod impact testing machines designed for accurate and repeatable readings with user-friendly operation. The machine supports fast specimen testing and helps manufacturers study material behavior before production and product application stages begin.
