This standard is a specialized part of the series for testing the fatigue properties of polymer matrix composites, specifically developed for adhesive-bonded joints. It details the test method for evaluating the fatigue performance of adhesives under tensile shear loading. It provides a unified testing procedure to assess the durability and service life of bonded joints under cyclic shear stress. Implementation of this standard requires testing instruments capable of applying cyclic tensile loads with constant amplitude and frequency to lap shear specimens, typically high-frequency fatigue testing machines or universal material testing machines with dynamic loading capabilities. The equipment must accurately record the number of cycles and load variations to determine the fatigue life of the adhesive at specific stress levels or to generate stress-cycle curves.
