How Long Is the Xenon Lamp Weathering Test Chamber Equivalent to a Year of Outdoor Exposure?

How long is the xenon lamp weathering test chamber equivalent to a year of outdoor exposure? How to test out its durability? This is a technical problem, but also a lot of users are concerned about the problem. Today's engineers of Lab Companion are going to explain this problem.

This problem looks very simple, in fact, it is a complex problem.We can not just get a simple number, let this number and the test time of the xenon lamp weathering test chamber to multiply, so as to get the outdoor exposure time, nor is the quality of our xenon lamp weathering test chamber not good enough! No matter how good the quality of the xenon lamp weathering test chamber is, how advanced it is, it is still impossible to find only a number to solve the problem. The most important thing is that the outdoor exposure environment is complex and changeable, affected by many factors, what are the specific?

1. The influence of geographical latitude

2. The influence of altitude

3. The influence of geographical environment when testing, such as wind speed.

4. The impact of the season, winter and summer will be different, summer exposure is 7 times the damage of winter exposure.

5. Direction of the test sample

6. Is the sample insulated or uninsulated? Samples placed on insulators will generally age much faster than those not placed on insulators.

7. Test cycle of xenon lamp weathering test chamber

8. Xenon lamp weathering test chamber operating temperature, the higher the temperature, the faster the aging

9. Testing of special materials

10. Spectrum distribution in the laboratory
