Product Code:SAE J2334
Title:Laboratory Cyclic Corrosion Test
Issuing Committee:Automotive Corrosion And Prevention Committee
Scope:The SAE J2334 lab test procedure should be used when determining cosmetic corrosion performance for a particular coating system, substrate, process, or design. Since it is a field correlated test, it can be used as a validation tool as well as a development tool. If corrosion mechanisms other than cosmetic or general corrosion are to be examined using this test, field correlation must be established.
