What Is an Impact Tester?
An impact tester is used to measure the amount of distortion, expansion, contraction, flatness, and surface cracking of a sample when it is subjected to impact.
The testing methods include: High-acceleration impact tester, in which products such as electronic devices are fixed to a test table and accelerated. Izod impact testing, in which one side of a specimen is fixed and impact is applied to the opposite side to measure the impact value. Charpy impact testing, in which both sides of a specimen are fixed and impact is applied to the center of the specimen to measure the impact value. Charpy impact testing is used to measure impact values. Other tests include the Plastics - Tensile Impact Strength Test, the DuPont Drop Impact Test, and the Dart Impact Test.
Uses of Impact Testers
Impact testers are used to determine whether or not a product, its components, or its materials have the specified impact strength or at what level of impact strength. When selecting impact testers, it is necessary to consider the size of the specimen to be tested, the size of the impact required, and safety requirements. In addition, the accuracy of the sensor used to measure the degree of distortion, expansion, or contraction of the specimen should also be carefully selected.
Principle of Impact Testers
The principle of impact testers is explained in the following sections, which are divided into High Acceleration Shock Testers, Izod Shock Testers, and Charpy Shock Testers for measuring mobile devices and other electronic devices.
1. High Acceleration Shock Testing Machine
High-acceleration impact testers are used to measure the degree to which a product is damaged by impact by fixing the product to be measured on a shock table and generating a waveform of impact acceleration on the table. This tester is used for electronic devices such as smartphones and notebook PCs.
2. Izod Impact Testers
This tester is used to measure the amount of deformation of a sample piece and the magnitude of impact at the time of breakage by fixing one side of the sample piece with an incision and applying an impact to the other side with the magnitude of the force of fixing.
3. Charpy Impact Testers
This tester is used to measure the amount of deformation of a specimen or the magnitude of impact at the time of breakage by fixing both ends of a specimen with a cut in the center and impacting the center of the specimen with a fixed force. At the time of breakage, the energy absorbed by the specimen at the time of breakage is calculated using the potential energy of the hammer that jumped up upon impact.
