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則》的規

定起草。

本文件是GB/T2423的第34部分。GB/T2423已經發布的部分見附錄NA。

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

循環試驗》，與GB/T2423.34—2012相比，除結構調整和編輯性改動外，主要技術變化如下：

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“預處理”的內容（見7.1，2012年版的6.1）；

e）更改了“溫度/濕度分循環描述”“低溫分循環描述”“無低溫暴露的24h循環描述”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”的內容（見7.4.5）；

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

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

度組合循環試驗》。

本文件做了下列最小限度的編輯性改動：

——為與現有標準協調，將標準名稱改為《環境試驗第2部分：試驗方法試驗Z/AD：溫度/濕

度組合循環試驗》；

——增加了附錄NA（資料性）“GB/T2423的組成部分”。

GB/T2423.34—2024/IEC60068?2?38:2021

引言

GB/T2423系列標準包括了環境試驗及其嚴酷等級的基礎信息，用于評定試驗樣品在預期的貯

存、運輸以及各種使用環境下的環境適應性。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系列標準旨在為產品規范制定者和產品試驗者提供一系列統一且可重復的氣候、機械和綜

合等環境試驗，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余項文件發布實施，現行GB/T2423標準文件48項，其

中40項采用IEC60068?2系列標準。現行GB/T2423系列標準組成部分詳見附錄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。

環境試驗第2部分：試驗方法

試驗Z/AD：溫度/濕度組合循環試驗

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

非另有規定，通電試驗樣品的測量通常在試驗的恒溫階段進行。
