Astm E466-21 |verified| | Desktop SAFE |

Feature a continuous radius between the gripping heads and the center gauge section to reduce stress concentrations.

is the latest version of a standard practice that outlines the procedure for performing force-controlled (load-controlled) , constant amplitude, uniaxial fatigue testing on metallic materials. The "21" designation indicates the year of the last approved revision—2021. astm e466-21

When should you use E466? — If your component sees millions of cycles at stresses below yield (e.g., valve springs, rotating shafts). Use E606 if your component sees few thousand cycles at high strains (e.g., seismic braces, thermal cycling). Feature a continuous radius between the gripping heads
