Proper Sample Preparation for ASTM E8
and Sheet Metal - Sample Grinding
After a tensile bar has been punched out on a press, the sides should be smoothed down with a grinding machine. When the sample is initially punched, the edges will be warped and compressed. This warping on the edges can effect tensile test measurements up to 5% and Poisson's Ratio measurements by up to 25%! It is highly recommended that the sample edges are ground down to ensure proper sample preparation for ASTM E8, ASTM A370, and other metal tensile tests.
