ASTM D4799 ASTM D4587 ASTM G154 QUV UV Aging Testing Chamber

ASTM D4799 ASTM D4587 ASTM G154 QUV UV Aging Testing Chamber Price

This testing chamber can simulate the harm caused by sunlight, rain, and dew. UV uses fluorescent ultraviolet UV lamps to simulate the effect of sunlight, and uses condensed moisture to simulate rain and dew. The tested materials are exposed to light and moisture at a certain temperature. Test in alternate cyclic programs. UV can reproduce the hazards that occur outdoors in months to years in a few days or weeks. UV test data can help you choose new materials and evaluate how changes in formulations affect the durability of new products.

Use:

1. The UV weathering tester is mainly used to simulate the damaging effects of sunlight, humidity and temperature on materials;

2. Material aging includes fading, loss of gloss, strength reduction, cracking, peeling, chalking and oxidation, etc.;

3. The UV weathering tester simulates sunlight, condensation, and natural humidity, and the sample is tested in a simulated environment for several days or weeks, which can reproduce the damage that may occur outdoors for months or years;

4. In the ultraviolet weathering test machine, the fluorescent ultraviolet of the ultraviolet lamp can reproduce the influence of sunlight, and the condensation and water spray system can reproduce the influence of rain and dew;

5. During the entire test cycle, the temperature is controllable;

6. A typical test cycle is usually ultraviolet light irradiation at high temperature and a dark and humid condensation cycle with a relative humidity of 100%;

7. Typical applications are paint coatings, automotive industry, plastic products, wood products, glue, anodic oxide film, etc.
