The Izod impact test evaluates a material's toughness by measuring its ability to resist impact force. The Izod impact test specimen is typically a notched bar placed vertically, and the test involves striking the specimen with a pendulum to determine the energy absorbed during fracture. Accurate specimen preparation and alignment are crucial for reliable results. In contrast, the scratch hardness tester measures a material’s surface resistance to scratches and abrasions, providing insights into its durability under wear conditions. While the Izod impact test focuses on impact resistance, the scratch hardness test assesses surface resilience. Together, these tests offer a comprehensive evaluation of material toughness and surface integrity, helping industries select robust materials for their applications.
