Xenon Light Weatherable Tester(Insolation Weatherable Tester)
KP-XD Xenon Light Weatherable Test is an important means of selecting for-
Mula and optimizing product combination as well as a key part of product quality inspection in scientific research and production;apply material like coating material,plastic material,aluminum-plastic panel,paint,safety glass for automobiles in the test in accordance with standard requirements.
The key factors of causing aging are sunlight and moisture.UV can simulate sunlight effect with fluorescent UV lamp and rainfall and dew with condensation moisture.Put tested material in the cyclic process of sunlight and moisture under certain temperature.UV can recreate the outdoor hazards with several weeks or years using several days or weeks.UV test data can help you choose new materials,transform existing materials and evaluate how formula changes effect durability of new product.
Test method for material
1. Black standard temperature and blackboard temperature:Use the following two temperature for reference in exposure test:65℃±3℃/100℃±3℃.(Note:the higher one is designed for special test).Above temperatures are not necessarily a priority.When the parties concerned reach an agreement by consensus,we can also choose other temperature and make an explanation of it in the test report.If using water spray,keep temperature constant during waterless interval.If the thermometer cannot reach the required temperature,specify the highest temperature during waterless interval.If the exposure device continuously works by the means of substitution,then black standard thermometer measures in the same way.If using blackboard thermometer,specify the type,settlement methods and working temperature.
2. Relative humidity:It should be selected to reach an agreement by consensus.The measured relative humidity inside the cabinet is not necessarily equal to neighbouring relative air humidity.
3. Spray period:It should be decided to reach an agreement by consensus,but it’s better to choose the following:spray time/time:18min±0.5min;waterless interval:102min±0.5min
4. Dark period:test method 1 and 3 are applicable to test with continuous illumination.We can choose a more complicated cycle period in this part like higher relative temperature,increase temperature and generate condensation.Specify detailed conditions during dark period in test report.
