Note: Nothing in this standard supercedes applicable laws and regulations.

Note: In the event of conflict between the English and domestic language, the English language shall take precedence. 

Purpose. This standard describes an accelerated corrosion test that can be combined with mechanical, electrical, and/or pneumatic inputs with environmental (chemical and thermal) inputs to produce realistic vehicle part or system wear and aging. This test is designed for corrosion replication of functional incidents and where galvanic corrosion mechanisms are present. 

Foreword. This is a cyclic environmental test, which exposes test items to periodic wetting with a salt/mud solution followed by drying all at an elevated temperature. If requested, forces or other dynamic inputs should be applied in a realistic manner consistent with the function of the item under test. The test requestor must define the test duration and the required component loading based on anticipated failure mechanisms and acceleration rates. 

Applicability. This procedure is applicable to passenger car and truck components or subassemblies. This test has shown good test-to-field correlation of accelerated galvanic corrosion with dynamic inputs.
