Scope
This lab test procedure should be used when evaluating the combined corrosion and fatigue performance for a particular coating system, substrate, process and design. The test is intended to provide an A to B comparison of a proposed coil spring design versus an existing field validated coil spring when subjected to the combined effects of corrosion and fatigue. The corrosion mechanisms covered by this test include general, cosmetic and pitting corrosion. Fatigue testing covers the maximum design stress and/or stress range of the coil spring design (typically defined as excursion from jounce to rebound positions in a vehicle). The effects of gravel and heat are simulated by pre-conditioning the springs prior to fatigue testing. Time dependant corrosion mechanisms such as stress corrosion cracking are not addressed with this test.
Rationale
The technical report covers technology, products, or processes for which technical expertise no longer resides in the owning committee.

Materials, Processes and Parts Council
The Materials, Processes, and Parts Council (MPPC) promotes, directs, supervises and provides for the development of consensus SAE Technical reports. The council also conducts investigations for activities related to engineered materials, processes and parts used in the surface mobility industry. Participants in the SAE Materials, Processed and Parts Council include OEMs, suppliers, consulting firms, government and other interested parties.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
