High UV, high humidity, and high rainfall (subtropical weathering).
While laboratory accelerated weathering tests (like ASTM G154 or ASTM G155 using artificial UV lamps) are fast, they cannot perfectly replicate nature. ASTM G7 serves as the "real-world" baseline. Companies frequently use ASTM G7 data to validate and calibrate their indoor laboratory test results. How to Get the Official ASTM G7 PDF
