前言

本文件按照GB/T1.1—2020《標(biāo)準(zhǔn)化工作導(dǎo)則第1部分：標(biāo)準(zhǔn)化文件的結(jié)構(gòu)和起草規(guī)則》的規(guī)

定起草。

本文件是GB/T2423的第34部分。GB/T2423已經(jīng)發(fā)布的部分見附錄NA。

本文件代替GB/T2423.34—2012《環(huán)境試驗第2部分：試驗方法試驗Z/AD：溫度/濕度組合

循環(huán)試驗》，與GB/T2423.34—2012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）在“范圍”中增加了不適用范圍的描述（見第1章）；

b）更改了“試驗概述”的內(nèi)容（見4.1，2012年版的3.1）；

c）更改了“濕熱試驗箱”中加濕用水的要求（見5.2，2012年版的4.1）；

d）更改了“預(yù)處理”的內(nèi)容（見7.1，2012年版的6.1）；

e）更改了“溫度/濕度分循環(huán)描述”“低溫分循環(huán)描述”“無低溫暴露的24h循環(huán)描述”中的步驟

及濕度值（見7.4.1、7.4.2、7.4.3，2012年版的6.4.1、6.4.2、6.4.3）；

f）增加了“中間檢測”的內(nèi)容（見7.4.5）；

g）更改了“試驗報告中應(yīng)給出的信息”的內(nèi)容（見第9章，2012年版的第8章）。

本文件等同采用IEC60068?2?38：2021《環(huán)境試驗第2?38部分：試驗方法試驗Z/AD：溫度/濕

度組合循環(huán)試驗》。

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Z/AD：溫度/濕

度組合循環(huán)試驗》；

——增加了附錄NA（資料性）“GB/T2423的組成部分”。

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，用于評定試驗樣品在預(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)有50余項文件發(fā)布實施，現(xiàn)行GB/T2423標(biāo)準(zhǔn)文件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。

本文件描述的組合試驗方法，主要用于元器件類試驗樣品，以加速方式來確定試驗樣品在高溫/高

濕和低溫條件劣化作用下的耐受性能。

1范圍

本文件描述了一種組合試驗方法，主要用于元器件類試驗樣品，以加速方式來確定試驗樣品在高

溫/高濕和低溫條件劣化作用下的耐受性能。

本文件不適用于在整個試驗過程中通電的試驗樣品。試驗樣品可以在試驗的恒溫階段通電。除

非另有規(guī)定，通電試驗樣品的測量通常在試驗的恒溫階段進行。

2規(guī)范性引用文件

下列文件中的內(nèi)容通過文中的規(guī)范性引用而構(gòu)成本文件必不可少的條款。其中，注日期的引用文

件，僅該日期對應(yīng)的版本適用于本文件；不注日期的引用文件，其最新版本（包括所有的修改單）適用于
