The standard provides a cyclic heat and humidity corrosion test method for high-strength aluminium alloys, primarily for research and development, or to evaluate the performance of produced materials in specific material specifications. The test simulates flaking corrosion behavior in marine and industrial environments, predicting the corrosion resistance of a material in harsh environments through constant immersion in a corrosion test solution. While the method can show the exfoliation resistance of aluminium alloys, the relevance to actual conditions of use still needs further verification. The standard applies to all forged aluminium alloy products, including sheets, extrusions and forgings, and requires users to establish appropriate safety and health practices prior to use.
