    Fatigue tests to determine the life of components, machines and structures are generally made on the actual parts or scaled models, or on test specimens designed to accommodate a specific type of loading. Fatigue tests to obtain S-Ndiagrams for materials are made with test specimens of relatively simple design for each product; for example, bar, sheet, tubing, and wire. Tubing and wire are usually tested with specimens of the same cross-section as the original product.
