How to Insert a Specimen into the ASTM D3410 Shear Fixture — Step-by-Step Demonstration

In this video, we demonstrate the proper method for inserting a composite specimen into an ASTM D3410 shear fixture for compression testing. ASTM D3410 is the standard used to determine the compressive properties of polymer matrix composites using the Combined Loading Compression (CLC) fixture, and correct specimen installation is essential for obtaining accurate, repeatable results.

We walk through the full setup process, including fixture alignment, clamping technique, and proper specimen positioning to help prevent slippage, uneven loading, or premature failure. This walkthrough is useful for technicians, lab personnel, and engineers working with advanced composite materials who want to improve consistency in their testing procedures.
