ASTM STANDARD E 1921 REQUIRES THAT SPECIMENS BE MACHINED to certain proportionality and precision requirements. Most important for obtaining good data is that the specimens should be fatigue pre-cracked exactly as specified. Test machines must have calibrated load cells, and test fixturing should be aligned properly.
