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。

The problems existing in accelerated weathering testing are discussed. The importance of outdoor exposure testing is illustrated. It is pointed out that outdoor exposure testing should be used to test accelerated weathering. With the right test procedure, outdoor exposure testing can achieve better test results in less time. Proper test design, proper evaluation methods, reliable statistical analysis and application of reference samples allow testers to determine acceleration and correlation coefficients between accelerated and outdoor exposure tests to ensure correct test results are accelerated.
