ASTM D7774 Test Fixture
Standard Test Method for Flexural Fatigue Properties of Plastics
4-point bend test fixture for reverse fatigue bending to determine the dynamic fatigue properties of plastics under flexural stress according to ASTM D7774 Procedure B
ASTM D7774 is a standard method for measuring the fatigue strength of plastic materials in bending. It's applicable to both stiff and slightly flexible plastics. The test involves repeatedly bending plastic samples to determine how well they withstand repeated stress. This information is useful for selecting the right plastic for applications where it will experience bending stress.
- Three- or four-point bending fixtures are used to apply stress to the plastic samples.
- Samples are bent back and forth in a cyclic manner until they break or fail.
- The test helps determine the influence of factors like manufacturing processes, surface quality, stress levels, and others on the fatigue resistance of plastics.
- The results of these tests can be used in designing products or structures made from plastic materials.
