ISO 21207-2015 Accelerated corrosion test (ACT) in artificial atmospheres, including alternating exposure to corrosion-promoting gases, neutral salt spraying and drying is an international standard designed to evaluate the corrosion resistance performance of metallic materials in harsh environments. The standard contains two accelerated corrosion test (ACT) methods (A and B) designed to simulate climate effects in outdoor environments, including salt pollution and corrosion-promoting gases in industrial or traffic environments. Test Method A simulates a moderately aggressive traffic environment, while Test Method B simulates a harsher industrial or traffic environment. These tests allow an assessment of the corrosion resistance of a product under real-world conditions of use, particularly for metal-sensitive products such as electronic components. The application of ISO 21207-2015 helps manufacturers improve product design and material selection to ensure long-term performance and durability in a wide range of environment conditions.
