ASTM D790 Testing

Applied Technical Services’ ASTM D790 testing procedures determine the flexural properties of unreinforced and reinforced plastics, electrical insulation materials, and high-modulus composites.
What is Flexural Strength, and Why is it Important?

Flexural strength, or bending strength, refers to the maximum bending stress a material can endure before it yields. Manufacturers rely on flexural strength testing to evaluate how products and materials resist deformation under stressful loads. Flexural strength tests aid manufacturers in various processes, including the following:

ASTM D790 Testing Explained

The ASTM D790 testing standard consists of two test procedures. Each method correlates to material’s specific strain limit. Procedure A, the preferred method, employs a strain rate of 0.10 mm/mm/min and is ideal for materials that break at small deflections. Procedure B works for materials that don’t yield or rupture within the 5% strain limit when following the protocol of Procedure A. 

Technicians prepare for the procedure by configuring the testing equipment to the client’s specifications. To begin the process, technicians lay a rectangular specimen across two supports before applying a load to the material. Technicians apply the load until the sample deforms or reaches a maximum strain of 5%. The ASTM D790 testing procedure provides information on the following:
