ASTM D256

ASTM D256 is a standardized test method used to measure a material's impact resistance, specifically its ability to withstand sudden force or shock without breaking. Commonly applied to plastics and polymers, the test involves striking a sample with a swinging weight and recording the energy absorbed before failure. This helps determine the material's toughness and suitability for different applications, ensuring safety and durability. The test provides consistent, comparable results across materials, guiding manufacturers and engineers in selecting the right materials for products that need to endure impact or sudden stresses.
