International Standards 3-Point Bending Test:
ASTM D790 - DIN EN ISO 178 - ISO 178 - a.o.
For the 3-Point Bending Test, our laboratory has a universal testing machine with load cells in various force ranges up to 150 kN.
As a deflection measuring device, we use a displacement transducer with the highest resolution, which meets the accuracy class 0.5 (ISO 9513). The use of a two-point sensor makes it possible to determine the deflection free from the effects of machine compliance and, in particular, to determine the bending modulus precisely and correctly.
With our equipment, we are able to accurately test the flexural strength, flexural modulus and other aspects of the flexural stress / flexural strain relationship of plastics and their compounds.
The 3-point bending test is a material testing method in which plastic samples are examined with regard to their bending behavior. A standardized, beam-shaped specimen is supported on two supports, while a force perpendicular to the specimen is applied in the center. The resulting deflection generates stresses in the material, which are used to determine the bending properties. The measurement is made until the specimen breaks or until a specified deflection is reached.
The 3-point flexure test is an important method for the characterization and quality control of plastics.
