ASTM D790 is the test method for the flexural properties of plastics and electrical insulating materials using three-point loading. To match this to your program, talk with our team.
What ASTM D790 Covers
It determines flexural strength and modulus of rigid and semi-rigid plastics, a common property for material selection and quality control.
How the Test Is Run
A bar specimen is supported near its ends and loaded at the center at a controlled rate, and flexural strength and modulus are calculated from the load-deflection response.
Why It Matters
Flexural properties rank plastic stiffness and strength in bending; a rigid three-point fixture and accurate deflection measurement are essential.
