About Flexural Testing

Flexural test methods determine the flexural properties of unreinforced and reinforced plastics and rubbery materials.  Flex testing is a mechanical testing system (MTS) method.  
 

  • Approaches

    Flexural test methods utilize either a three-point or a four-point loading system applied to a supported beam.

    Flexural properties, as determined by these test methods, are especially useful for quality control and specification purposes.  Other purposes include:

    • Product comparison
    • Material development
    • Determination of mechanical property degradation as a result of product use, accelerated aging, or response to chemical exposure.

    ASTM Methods:

    • D790
    • D6272
  • Sample Considerations

    Typical samples are 7-15cm long.

    The width or thickness of a sample can vary based on the material.

    Flexural test methods are generally applicable to both rigid and semi rigid materials.

    Standard specimens or molded products can be tested.

  • Experience

    Products we've tested:

    • Liners for cure in place pipe (CIPP)
    • Dental implant materials
    • Power transmission components for automobiles
    • Dilation catheter
    • Orthopedic anchors and splints

    Work we've done:

    • Aged materials testing (compare the stiffness or rigidity over time and through use)
    • Strength testing of materials (ensuring they will be strong enough for a certain application)
    • Ensuring a material is meeting specifications
    • Developing specifications
