How do I determine the test time for the Xenon Arc Weatherometer?

Xenon Arc Weatherometers reproduce weathering damage by sunlight, temperature, humidity and water spray. 

 

When Xenon Arc Weatherometer is in operation, customers often want to know how long the accelerated weathering test should be conducted to correspond to 5, 8, 10 years, etc. It can be clearly said that there is no such correspondence, which is due to the diversity of materials, the diversity of material formulations, climate diversity and many other complex factors, and the conditions of the Xenon Arc Weatherometer test are relatively fixed, but it is just a number of cycles of the same test conditions. So, what to do at this point? There are several methods for reference.

1, refer to the relevant product standards

 

Many products or materials manufacturers have made provisions for the aging test time in their product standards, we just need to test according to the standard time and conditions, many international standards, national standards and industry standards also have specific provisions for reference.

 

2、According to the existing correlation conversion formula for projection

 

Artificial accelerated aging and natural exposure correlation research has been in progress, there are also many conversion formula, but only limited to specific materials, if it happens that you happen to, then congratulations, you can project to a relatively reliable use of years.

 

3, control the total amount of artificially accelerated aging radiation and natural exposure to total radiation equivalent

 

For example, the total amount of natural exposure radiation in a certain area throughout the year is relatively small difference, want to test in this area of a certain material can be used for 5 years, then you can know the total amount of natural exposure radiation for 5 years, and then by controlling the artificial accelerated aging radiation weight to the total amount of natural exposure radiation for 5 years to determine the test time. However, it should be noted that this is generally speaking also unreliable, for information purposes only, but of course, if the standard is so specified or agreed, it is okay to do so.
