The standard addresses a specific engineering concern: . Unlike a single overload that causes immediate fracture, fatigue happens slowly, over thousands or millions of cycles. Classic examples include a bridge component cracking under decades of traffic vibrations or an aircraft wing spar failing after repeated pressurization cycles.
ASTM E466-15 outlines the practice for force-controlled, constant-amplitude axial fatigue testing of metallic materials to evaluate fatigue resistance. It focuses on elastic strain behaviors for notched or unnotched specimens, typically generating S-N curves in room-temperature air.

ASTM E466-15 provides the standard practice for force-controlled constant amplitude axial fatigue testing of metallic materials in high-cycle, elastic range conditions. The procedure dictates specific specimen preparation and servo-hydraulic testing methods to generate accurate S-N curves and define fatigue limits.
