ASTM E466 Testing — Laboratories & Overview
ASTM E466 describes practice for force-controlled constant amplitude axial fatigue tests on metallic materials, the basis of many S-N data programmes.
When is it used?
- Generating S-N curves for design
- Comparing material or process fatigue performance
- Substantiating cyclic life requirements
Sample considerations
- Specimen surface preparation and alignment strongly affect results.
- Load ratio, frequency and run-out definition must be agreed before starting.
