UV Accelerated Weathering Test Chamber
Introductions
This test equipment simulates the damage caused by the sun's ultraviolet light, by exposing the material under test to light at a controlled high temperature to test the material for weathering. It uses UV lamps to simulate the radiation effect of sunlight, and simulates dew and rain through condensation and water spray. In just a few days or weeks, the UV irradiation equipment can reproduce the damage that takes months or even years to occur outdoors, including fading, color change, loss of gloss, chalking, cracking, crazing, wrinkling, blistering, brittleness, strength reduction, oxidation, etc. The test results can be used to select new materials, improve existing materials, or evaluate changes in material formulations.
Fetures
1. To irradiance, temperature, time and other important test parameters to provide comprehensive and detailed real-time monitoring and curve records (controller with paperless recorder function), through the computer can also generate reports and curve printing.
2. Irradiation/condensation/water spray test can be conducted separately, and any combination of irradiation/condensation/water spray test can be programmed.
3. Adopt South Korea Sanyuan level 5.7 inch true color touch screen control system, which has good stability, monitoring, operation and maintenance.
4. Provide life reference for the imported UV lamp with expensive material (the lamp is consumable and the life is about 1600 hours), which is convenient for users to confirm the replacement time of the lamp and save the cost of use. Through irradiance measurement and control device (by adjusting the voltage), irradiance can be measured and controlled, so that the irradiance is automatically stabilized at the set value and the service life of the lamp is greatly extended.
5. Adopt automatic water supply and drainage design, and match with high power water mercury of higher cost, to ensure the flow rate and uniformity of water spraying.
6. Most of the main components use international brands, and a small part uses domestic brands to improve the safety and reliability of the product. (For details, please refer to the attached list of main components.)
7. The installation and wiring of the electrical part of the equipment are executed in accordance with international electrical standards.
8. Perfect professional after-sales service.
Test Standards:
IEC61215, ASTM D4329,D499,D4587,D5208,G154,G53; ISO 4892-3,ISO 11507; EN 534; BS 2782; JIS D0205; SAE J2020,ect.
Test theory:
UV accelerated aging test chamber can simulate the damage of sunshine, rain, dew to the material quickly and exactly. Damage types including bleaching, discoloration, loss of light, powder, crack, turbidity, bubble-based, embrittlement, strength decline and oxidation need to be engenderd in months or years but can engender in a few days or weeks.

FAQ
A. What is the UV weathering test method?
UV Exposure testing uses fluorescent UV lamp weathering devices to simulate exposure to natural sunlight. This test measures the effect of ultraviolet light on the mechanical properties of a product.
B. How do you test weathering?
1. Some of the accelerated weathering testing conditions simulated in the test lab include:
2. Solar exposure to natural, ultraviolet and infrared light.
3. Water exposure through simulated rain, condensation, and mist.
4. Temperature fluctuations from extreme heat and cold.
5. Salt and corrosion conditions.
C. What are the two biggest factors that determine weathering?
Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering.
