前言

本文件按照GB/T1.1—2020《標準化工作導則第1部分：標準化文件的結構和起草規(guī)則》的規(guī)

定起草。

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，除結構調(diào)整和編輯性改動外，主要技術變化如下：

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）“相關規(guī)范中應給出的細節(jié)”更改為“相關規(guī)范應給出的信息”，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)有標準協(xié)調(diào)，將標準名稱改為《環(huán)境試驗第2部分：試驗方法試驗Ka：鹽霧》；

—增加了附錄NA（資料性）“GB/T2423的組成部分”。

GB/T2423.17—2024/IEC60068?2?11:2021

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信息，用于評定試樣在預期的貯存、運輸

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

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系列標準先后有50余項文件發(fā)布實施，現(xiàn)行GB/T2423標準48項，其中

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

本文件規(guī)定的試驗目的在于比較電工設備、部件和材料抗鹽霧腐蝕的能力。

本試驗能用于評價防護涂層的質(zhì)量和均勻性。

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

化電工設備、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

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。

本文件描述了評估在鹽霧環(huán)境中電工產(chǎn)品部件、設備和材料抗腐蝕能力的試驗方法。

本試驗方法旨在對有腐蝕防護和沒有腐蝕防護的某金屬材料在暴露于鹽霧后所維持的狀態(tài)進行質(zhì)量

比較驗證。
