How long UV Aging Test Chamber Sample Time = 1 Year Outdoor Exposure

How many hours in UV Aging Test Chamber is equivalent to one year of outdoor exposure? This data is not available to verify.

 

It seems to be a simple question, but the answer is a complex one. Theoretically, we cannot get a simple number and multiply it with the UV Aging Test Chamber test time to get the outdoor exposure time. The reason is not that we have not developed a test chamber to meet this requirement of customers, but whether your aging test chamber is imported or the price is very high, or can not find this figure.

In fact, the biggest problem is that the outdoor exposure environment is complex and unpredictable. UV Aging Test Chamber in the test time and outdoor exposure time and the following factors are related to: in logic to talk about the artificial accelerated aging time and outdoor exposure length conversion factor is not meaningful. The reason is that one is a fairly constant environment, while the other is highly variable. Finding a conversion factor between the two is beyond the range of variability. In other words, weather data is relative data.

 

Still, you can get excellent weathering test data from an artificial UV Aging Test Chamber. But you must recognize that the data is relative data, not absolute data. The reliable data you get from laboratory tests is the relative rating of the material under test for aging compared to other materials.
