The impact testing method is pivotal for determining a material’s ductile-to-brittle transition temperature and its ability to resist deformation due to impact loads.Mechanical testing covers a wide range of tests, which can be divided broadly into two types: . those that aim to determine a material's mechanical properties, independent of geometry. [1]those that determine the response of a structure to a given action, e.g. testing of composite beams, aircraft structures to destruction, etc. Impact testing is a mechanical test method utilized to determine the properties of a material when subjected to high-speed impact forces. This test involves applying a known amount of energy to a material sample and measuring the amount of energy that is absorbed by the material before it breaks or fractures. Impact strength is measured by allowing a pendulum to strike a grooved machined test piece and measuring the energy absorbed in the break (AS1544). The Izod test is at ambient temperature while the temperature controlled Charpy test (AS1544.2) uses typically 10x10mm, rectangular cross section samples cut at specified orientations to the .

Test Methods to Determine Impact Resistance of Coatings Impact tests signify toughness, or impact strength, of a coating to absorb energy under mechanical load. The drop impact test (or falling-weight impact test) is a commonly used test method to determine the impact resistance. The test standards used for impact resistance testing include: An Izod impact testing apparatus — which is essentially identical to a Charpy impact testing machine — is used to determine Izod impact strength. The primary differences between the Izod and Charpy impact tests are the size of the test specimen, how it is restrained, and which side is struck by the pendulum hammer.
