What methods are used for vehicle corrosion testing?

Corrosion testing methods include: Accelerated laboratory tests (salt spray, cyclic corrosion tests like GMW 14872), proving ground exposure routes (stone chipping, salt exposure, water fording), outdoor exposure yards (coastal, industrial environments), and electrochemical measurements (corrosion potential, rate). Tests evaluate both cosmetic corrosion (appearance) and perforation (structural integrity). Targets typically include 3 years cosmetic and 10+ years perforation-free. Testing validates coating systems, drainage design, material selection, and sealing effectiveness.
