ASTM D790
Standard Test Methods for Flexural Properties of Unreinforced and Reinforced Plastics and Electrical Insulating Materials

ASTM D790 is a method for determining the flexural properties of plastics. In this test, the specimen is typically placed on two supports and loaded at the center until it bends or breaks. The material’s response is measured as it deflects under load.
Understanding the flexural properties of plastics is crucial for applications where plastics will experience bending or flexing forces, such as in automotive, construction, and consumer goods. ASTM D790 helps manufacturers select appropriate materials for design and quality control purposes.
