GB/T2423.65—2024

引言

GB/T2423系列標(biāo)準(zhǔn)包括了環(huán)境試驗(yàn)及其嚴(yán)酷等級(jí)的基礎(chǔ)信息，用于評(píng)定試樣在預(yù)期的貯存、運(yùn)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(gè)文件分別介紹了一組試驗(yàn)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(yàn)者提供一系列統(tǒng)一且可重復(fù)的氣候、機(jī)械和綜合

等環(huán)境試驗(yàn)，并包含了測(cè)量和試驗(yàn)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(xiàng)文件發(fā)布實(shí)施，現(xiàn)行GB/T2423標(biāo)準(zhǔn)文件48項(xiàng)，其中

40項(xiàng)采用IEC60068?2系列標(biāo)準(zhǔn)?，F(xiàn)行GB/T2423系列標(biāo)準(zhǔn)組成部分詳見附錄A。

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

料影響的模擬試驗(yàn)方法。金屬材料受氯化物作用發(fā)生電化學(xué)腐蝕，有機(jī)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(yàn)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(shí)加載能有效的模擬含鹽大氣與陽光同存時(shí)的腐蝕老化環(huán)境，干熱與太陽輻

射能有效模擬強(qiáng)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(yàn)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(hù)及環(huán)境適應(yīng)性能。

本文件描述的試驗(yàn)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(gè)綜合加速系數(shù)。雖然綜合試驗(yàn)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(shí)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(duì)耐久性。盡管

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