|accelerated weathering test;加速老化试验
加速老化测试(Accelerated Aging Test) 是一种在实验室环境中,通过施加比正常使用条件更严苛的环境应力(如升高温度、湿度、光照强度、机械应力等),来快速评估产品或材料在长期使用或储存后性能变化和寿命的可靠性试验方法。其核心目的是在相对较短的时间内,预测产品在自然老化条件下的耐久性和失效模式。

accelerated aging test(加速老化试验)是一种通过提高环境条件来模拟材料或产品长期老化过程的测试方法,主要用于评估其耐久性和性能变化。以下是详细解释:
核心原理
通过施加高强度环境应力(如高温、高湿、强光照、化学腐蚀等),加速材料或产品的老化过程,从而在较短时间内预测其正常使用条件下的寿命和可靠性。例如,食品行业常用此方法评估储存期,电子行业则用于测试元件耐久性。
应用领域
关键要求
测试需确保加速条件不改变失效机理,否则结果无效。例如,若高温导致材料熔化而非自然老化,则测试不适用。
相关术语
该测试通过极端条件缩短评估周期,是质量控制和研发中重要的效率工具,但需科学设计以保持结果可靠性。
