GB/T 39524-2020 specifies the test method for the weather resistance of building doors and windows. This method utilizes laboratory equipment to simulate the accelerated aging effects of climatic factors such as sunlight, temperature, and rainwater on doors and windows. After testing, changes in key performance indicators such as opening and closing force, air tightness, and water tightness are inspected to evaluate their durability for long-term use.
