|accelerated weathering test;加速老化試驗
加速老化測試(Accelerated Aging Test) 是一種在實驗室環境中,通過施加比正常使用條件更嚴苛的環境應力(如升高溫度、濕度、光照強度、機械應力等),來快速評估産品或材料在長期使用或儲存後性能變化和壽命的可靠性試驗方法。其核心目的是在相對較短的時間内,預測産品在自然老化條件下的耐久性和失效模式。

accelerated aging test(加速老化試驗)是一種通過提高環境條件來模拟材料或産品長期老化過程的測試方法,主要用于評估其耐久性和性能變化。以下是詳細解釋:
核心原理
通過施加高強度環境應力(如高溫、高濕、強光照、化學腐蝕等),加速材料或産品的老化過程,從而在較短時間内預測其正常使用條件下的壽命和可靠性。例如,食品行業常用此方法評估儲存期,電子行業則用于測試元件耐久性。
應用領域
關鍵要求
測試需确保加速條件不改變失效機理,否則結果無效。例如,若高溫導緻材料熔化而非自然老化,則測試不適用。
相關術語
該測試通過極端條件縮短評估周期,是質量控制和研發中重要的效率工具,但需科學設計以保持結果可靠性。
