The BMW AA-0224 standard is a 7-day Cyclic Corrosion test to verify the corrosion behavior of surface coatings and gluing agents. The test cycle consists of three stages: salt fog spray, condensate exposure and room temperature regeneration. The specific steps include 24-hour salt fog spray, followed by room temperature condensate test and regeneration to simulate corrosion in the real environment and evaluate the corrosion resistance of protective coatings and gluing agents.
