This standard primarily specifies an outdoor accelerated corrosion test method for evaluating the weather resistance of metals and alloys, as well as their surface coating materials. The core of this method involves the use of a tracking solar exposure test device that continuously aligns with the sun, along with a tracking solar reflector concentrator device that gathers more solar radiation, thereby accelerating the aging process of materials. The standard details the principles of the test, the required equipment and instruments, specific operational procedures, and methods for data recording and result processing. During the test, instruments such as thermohygrometers and pyranometers are required to monitor environmental parameters. This method is mainly applicable to materials such as organic coatings, composite materials, and plastic coatings based on metals and alloys, aiming to provide a technical basis for evaluating the weather resistance of products in industries such as metallurgy, automotive, and aerospace.
