Impact test
This test measures the impact resistance of a material or coating and studies how a material absorbs the energy during an impact.
Can be applied to:
metals, plastics, composites, coatings
Test method standards:
EN ISO 148-1, ISO 179, ISO 148, ISO 6272, ASTM D2794
Test procedures:
1. Charpy test
The Charpy impact test or Charpy V-notch test is a standardised test which determines the amount of energy absorbed by a material during fracture. We conduct these tests with notched test bars and/or a pendulum hammer to create the impact.
The test can be conducted at different low temperatures to simulate the behaviour of the material in real industrial conditions.
2. Falling Dart Pass/Fail test
The falling dart or impact test is a common test to check the flexibility, adhesion and impact resistance of a coating.
The test can either be used as a pass/fail test to check if a coating matches a predefined specification, given by a minimum height of a falling dart with specific diameter and weight. The coating surface after impact is evaluated and should be free of cracks or coating delamination.
The impact resistance of a coating can also be expressed by a combination of height and weight at which the coating shows the first signs of damage.
Lead time:
From 5 to 10 business days
All tests – composites – metals – plastics – coatings – adhesives – 3D prints
