Effect)而出現(xiàn)表面濕氣吸附，滲入、凝結(jié)等情形，在低濕環(huán)境中會因靜電荷累積效應誘發(fā)產(chǎn)品出現(xiàn)失效。除了戶外型品必須執(zhí)行結(jié)露試驗(Condensation test)外，通常對室內(nèi)使用產(chǎn)品在濕度試驗過程中應避免水氣凝結(jié)(Condensation)情形出現(xiàn)，因水氣凝結(jié)易造成產(chǎn)品線路出現(xiàn)短路現(xiàn)象而造成失效。高溫試驗用來考核試驗樣品在高溫條件下貯存或使用的適應性。蘇州產(chǎn)品環(huán)境可靠性測試單位有哪些</p><div
