Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:

ASTM D6272 – Flexural Properties Testing of Unreinforced and Reinforced Plastics by Four-Point Bending

To request a quotation for any test email info@trl.com for a prompt reply

ASTM D6272 testing measures force, center span displacement and strain in four-point bending. This test method covers the determination of unreinforced and reinforced plastics, including high-modulus composites and electrical insulating materials in the form of rectangular bars molded directly or cut from sheets, plates or molded shapes. Touchstone is also able to perform eh technically equivalent standard ISO 14125 (Method B) – Determination of Flexural Properties of Fiber-Reinforced Plastic Composites.

After testing and analyzing the data, maximum strain in outer fibers of the specimen, flexural strength, tangent modulus of elasticity in bending, flexural yield strength, flexural offset yield strength and stress at any given strain up to 5% will be reported. Flexural properties determined by this test method are most commonly used for quality control and specification purposes.

Please email info@trl.com or call (304) 547-5800 for information regarding test procedures, results, specimen information, pricing or any other ASTM D6272 questions you may have. Touchstone Engineers are experienced in flexural testing of many materials and will be able to help if you are unsure whether the material should be tested using a three-point bend fixture (ASTM D790) or a four-point bend fixture (ASTM D6272).
