Impact Resistance Testing

 

The object is to subject the product to an impact load in flexion, tensile or torsion. In general, the energy absorbed during the rupture is measured by a single impact, for example in a Charpy, Izod impact test or a tensile impact test. There are also impact tests in which the sample is subjected to several impacts of increasing intensity, for example in the ball impact test or the repeated impact test.

 

examples of impact testing include

  • Impact with balls: These balls are made of hardened steel with a chrome finish and is equipped with a removable eyelet to allow the direct drop or the use in pendulum. Falls can vary in height and angle according to the specifications of applicable standards
  • Impact with the spring hammer: In this test, it is a question of striking the surface of the prototype with the spring hammer calibrated to a certain force. The interpretation of the results obtained will be specific to each of the standards
  • Ball pen hammer Hammer: 1 Lb. / 16 oz: It is a question of striking the surface of the prototype
