1. The fixed device for the test sample is placed on the test rack. When facing the fluorescent lamp, if the sample rack is not filled with the sample, a blackboard is needed to fill the sample rack and keep the inner wall of the test box closed.
2. Test temperature: When exposed to light, three temperatures of 50 ℃, 60 ℃, and 70 ℃ can be used, with 60 ℃ being the preferred temperature; The temperature during the condensation stage is 50 ℃, with a temperature tolerance uniformity of ± 2.
3. The condensation cycle for each illumination can be selected from two cycles: 4H illumination and 4H condensation, or 8H illumination and 4H condensation.
4. After 400-450H of * lighting, each row of lamps needs to be replaced with a fluorescent lamp, and other lamps should be compensated for the losses caused by lamp aging according to the lamp cycle and replacement method. This operating mode ensures that the service life of each lamp tube is between 1600-2000H.
5. When replacing the lamp tube, the water tray should be wiped dry and cleaned to avoid the formation of scale.

GB/T14522-93 "National Standard of the People's Republic of China - Plastic, Coating, and Rubber Materials for Mechanical Industry Products - Accelerated Test Method for Artificial Climate"
GB/T16585-1996 "National Standard of the People's Republic of China - Test Method for Artificial Climate Aging of Vulcanized Rubber (Fluorescent UV Lamp)"
Design and manufacture of corresponding standard clauses such as GB/T16422.3-1997 "Plastic Laboratory Light Source Exposure Test Method"

The UV weathering test chamber uses a fluorescent UV lamp as the light source to simulate the UV radiation and condensation in natural sunlight, and conducts accelerated weather resistance tests on materials to obtain the results of material weather resistance.
Simulate environmental conditions such as UV, rain, high temperature, high humidity, condensation, and darkness in natural climate, reproduce these conditions, merge them into a cycle, and let it automatically complete the cycle times.
