ASTM D790 | Plastics and Elastomers | Bend Testing
ASTM D790 is one of the most commonly used specifications in the plastics industry. This test measures the flexural strength and flexural modulus of reinforced and unreinforced plastics. These calculations relate to the stiffness of your material and allow you to choose materials that do not bend when supporting the loads you require for your application. The test uses a universal testing machine and a three point bend fixture to bend plastic test bars to acquire the data needed to make the calculations.
Prior to conducting ASTM D790, it is important to read the entire specification in the relevant ASTM publication.
