Note1: Where both tension and hardness tests are performed, the tension tests shall take precedence for acceptance purposes.
Note2: The yield and tensile streng1h values for full-size products shall be computed by dividing the yield and maximum tensile load by the stress area for the product diameter and thread pitch as given in table on tensile stress areas
