    Abstract

    The flexural fatigue resistance of plastics as determined by ASTM Test for Flexural Fatigue of Plastics by Constant-Amplitude-of-Force (D 671-71) employs a technique that permits the testing of only a single specimen at a time. By contrast, the test based on constant-amplitude-of-deflection of the specimen proposed in this paper accommodates up to 16 specimens simultaneously, thereby substantially reducing the time required for the test. Constant-amplitude-of-deflection of the specimen is effected by rotation of its builtin end. Experimental data are presented that show that both methods give substantially comparable results for nylon 6/6 and acetal homopolymer. A brief description of the apparatus required for the new test is also given.
