What is an impact testing machine?

Impact testing machines are used in the plastic and metal industries to understand material strength, durability and failure behavior. Impact testing is achieved by either a pendulum impact machine or a drop weight tester.

Impact testing machines release high amounts of energy between 0.5 joules and several kilojoules for each test. Test specimens are often notched to observe behavior at a single fracture and various temperatures. These tests are often performed on numerous samples of similar materials to understand which would perform best for a given application. To ensure accurate results, produce test specimens from the same machine using the same methods.
