This lab test procedure should be used when evaluating the combined corrosion and fatigue performancefor a particular coating system, substrate, process and design. The test is intended to provide an A to Bcomparison of a proposed coil spring design versus an existing field validated coil spring when subjectedto the combined effects of corrosion and fatigue. The corrosion mechanisms covered by this test includegeneral, cosmetic and pitting corrosion. Fatigue testing covers the maximum design stress and/or stressrange of the coil spring design (typically defined as excursion from jounce to rebound positions in avehicle). The effects of gravel and heat are simulated by pre-conditioning the springs prior to fatiguetesting. Time dependant corrosion mechanisms such as stress corrosion cracking are not addressedwith this test.
