户外测试检验加速测试

Outdoor Weathering Must Verify Accelerated Testing

探讨了加速老化测试存在的问题,阐述了户外暴露测试的重要性,指出应该利用户外暴露测试来检验加速老化。使用正确的测试程序,户外暴露测试可以在较短的时间内获得较好的测试结果。采用正确的测试设计、恰当的评估方法、可靠的统计分析及应用参照样品等,可使测试者确定加速程度及加速测试与户外暴露测试的相关系数,以确保加速测试结果的正确性。

In this paper,we will discuss the inherent problems that accelerated testing can have,and show techniques that can be used to ensure that the results from the accelerated testing are correct.Outdoor weathering must be used to verify accelerated testing,and it is possible with the correct testing procedure to get meaningful data from an outdoor test in a short time frame.Those techniques include correct experimental design,proper evaluations,control materials,and the use of reliable statistical analysis.These processes will allow the user to determine acceleration and correlation factors and will ensure that the accelerated testing is giving right results.
