The impact test is used to observe the mechanism of the material that how the material will react when it is subjected to instant shock that causes immediate deformation, rupture or fracture of the sample completely. To perform this test, the sample is placed into a holding fixture with the specific orientation or geometry and then a known weight is applied on the sample in the shape of the pendulum so that it get collides with the sample with quick force. This collision between the specimen and weight results in the deformation of the specimen but the transfer of energy between the two substances initiates the fracture in the material.
The test is performed to measure the strength of the material to tolerate energy when it collides with some other substance before it gets ruptured. In other terms, it is performed to measure the impact strength, toughness, fracture, impact resistance strength, etc. depending upon the type of sample and requirement of the application. This value helps the manufacturers in different industries to select the most appropriate material that can be used for a specific application. The test is performed on numerous materials such as plastics, glass bottles, metals, etc. Presto offers a wide range of impact strength testers for different production verticals to measure the strength of the products.
