本文件是GB/T2423的第17部分。GB/T2423已經(jīng)發(fā)布的部分見附錄NA。

本文件代替GB/T2423.17—2008《電工電子產(chǎn)品環(huán)境試驗第2部分：試驗方法試驗Ka：鹽

霧》，與GB/T2423.17—2008相比，除結(jié)構(gòu)調(diào)整和編輯性改動外，主要技術(shù)變化如下：

a）更改了“范圍”內(nèi)容（見第1章，2008年版的第1章）；

b）增加了“概述”（見第4章）；

c）“鹽霧”更改為“鹽溶液”，并更改了內(nèi)容（見第5章，2008年版的第3章）；

d）更改了“試驗設(shè)備”內(nèi)容（見第6章，2008年版的第2章）；

e）增加了“試樣”一章（見第7章）；

f）在“預(yù)處理”一章中將“注”的內(nèi)容調(diào)整為正文內(nèi)容（見第9章，2008年版的第5章）；

g）增加了“試樣的安置”一章（見第10章）；

h）“條件試驗”更改為“運行條件”，并更改了內(nèi)容（見第11章，2008年版的第6章）；

i）增加了“試驗持續(xù)時間”一章（見第12章）；

j）“相關(guān)規(guī)范中應(yīng)給出的細節(jié)”更改為“相關(guān)規(guī)范應(yīng)給出的信息”，并更改了內(nèi)容（見第15章，

2008年版的第10章）；

k）更改了“試驗報告”內(nèi)容（見第16章，2008年版的第9章）。

本文件等同采用IEC60068?2?11:2021《環(huán)境試驗第2?11部分：試驗方法試驗Ka：鹽霧》。

本文件做了下列最小限度的編輯性改動：

—為與現(xiàn)有標(biāo)準(zhǔn)協(xié)調(diào)，將標(biāo)準(zhǔn)名稱改為《環(huán)境試驗第2部分：試驗方法試驗Ka：鹽霧》；

引言

GB/T2423系列標(biāo)準(zhǔn)包括了環(huán)境試驗及其嚴(yán)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(biāo)準(zhǔn)中，每個文件分別介紹了一組試驗和應(yīng)用。

GB/T2423系列標(biāo)準(zhǔn)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(biāo)準(zhǔn)大氣條件。

1981年以來，GB/T2423系列標(biāo)準(zhǔn)先后有50余項文件發(fā)布實施，現(xiàn)行GB/T2423標(biāo)準(zhǔn)48項，其中

40項采用IEC60068?2系列標(biāo)準(zhǔn)。現(xiàn)行GB/T2423系列標(biāo)準(zhǔn)組成部分詳見附錄NA。

本試驗引起的劣化與電工設(shè)備、部件和材料長期暴露于含鹽環(huán)境之間的關(guān)系難以確定，不是用于量

化電工設(shè)備、部件和材料的長期老化的可靠方式。本試驗通常會因鹽霧引起加速劣化，為比較電工設(shè)

備、部件和材料在含鹽環(huán)境中的抗腐蝕能力提供了有效方法。
