引言

GB/T2423系列標準包括了環(huán)境試驗及其嚴酷等級的基礎(chǔ)信息，用于評定試樣在預(yù)期的貯存、運輸

以及各種使用環(huán)境下的環(huán)境適應(yīng)性。在該系列標準中，每個文件分別介紹了一組試驗和應(yīng)用。

GB/T2423系列標準旨在為產(chǎn)品規(guī)范制定者和產(chǎn)品試驗者提供一系列統(tǒng)一且可重復(fù)的氣候、機械和綜合

等環(huán)境試驗，并包含了測量和試驗用標準大氣條件。

1981年以來，GB/T2423系列標準有50余項文件發(fā)布實施，現(xiàn)行GB/T2423標準文件48項，其中

40項采用IEC60068?2系列標準。現(xiàn)行GB/T2423系列標準組成部分詳見附錄A。

本文件描述了用于檢驗鹽霧、太陽輻射、溫度和相對濕度等環(huán)境因素對電工電子設(shè)備、零部件和材

料影響的模擬試驗方法。金屬材料受氯化物作用發(fā)生電化學腐蝕，有機材料受太陽輻射作用而發(fā)生光熱

老化。腐蝕老化速率在很大程度上取決于試樣所處環(huán)境的溫濕度、表面含溶解氧的鹽溶液分布、試樣的

溫度以及太陽輻射。

本綜合環(huán)境試驗通過組合鹽霧、干熱、濕熱和太陽輻射等環(huán)境條件考察試樣可能出現(xiàn)的失效現(xiàn)象。

濕熱、鹽霧與太陽輻射的同時加載能有效的模擬含鹽大氣與陽光同存時的腐蝕老化環(huán)境，干熱與太陽輻

射能有效模擬強光狀態(tài)下的老化環(huán)境，濕熱與鹽霧則模擬高濕、含鹽大氣的腐蝕環(huán)境。通過以上試驗條

件的組合，最終考察電工電子設(shè)備、零部件和材料的綜合防護及環(huán)境適應(yīng)性能。

本文件描述的試驗與大多數(shù)預(yù)期使用條件相比較是加速的。不同材料的加速并不一致，難以為各種

不同類型的試樣建立一個綜合加速系數(shù)。雖然綜合試驗的濕熱、鹽霧、干熱和太陽輻射的環(huán)境條件能得

到控制，但是仍不能模擬實際使用的暴露條件，由此獲得的是設(shè)備、零部件和材料的相對耐久性。盡管

如此，本文件所描述的方法仍是一種有效檢驗產(chǎn)品質(zhì)量的方法。
