MECHANICAL TESTING LABORATORY

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

ASTM D7791 – Uniaxial Fatigue Properties of Plastics

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

ASTM D7791 covers the determination of dynamic fatigue properties of rigid and semi-rigid plastics in uniaxial loading.

Specimens of rectangular or circular cross section are gripped and then run loaded cyclically in either tension or compression. Testing continues until the specimen ruptures in the gage area

These tests can be used to determine the effect of processing, surface condition, and stress on the fatigue resistance of plastic material subjected to uniaxial stress for relatively large number of cycles.

Please email info@trl.com or call (304) 547-5800 for information regarding test procedures, results, specimen information, pricing or any other ASTM D7791 questions you may have.
