The ASTM D6675-23 standard describes an accelerated method for testing the corrosion performance of organic coatings in salt environments. This method simulates the actual use of steel plates in high-salt environments such as de-icing salts or coastal areas, and evaluates the corrosion resistance of coatings through outdoor exposure and salt solution wetting. The testing process involves using control samples for comparison to ensure the Reliability of the test results and takes into account the influence of climate, pollution and other factors on corrosion.
