ASTM D5894-21 standard practice specifies a test method for cyclic salt fog/UV exposure of painted metals. This method simulates the weathering resistance of coatings under various environmental conditions by alternately exposing samples in fog/dry cabinets and UV/condenser cabinets. This test helps to evaluate the ability of coatings to protect metal substrates under long-term exposure to salt fog and UV environments. It is suitable for Reliability detection of Coating masses and their performance prediction in harsh environments. This standard provides an important basis for evaluating the corrosion resistance and weathering resistance of Coating products, which are widely used in automotive, construction and other industries.
