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(lái)，GB/T2423系列標(biāo)準(zhǔn)先后有50余項(xiàng)文件發(fā)布實(shí)施，現(xiàn)行GB/T2423標(biāo)準(zhǔn)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(jiàn)附錄NA。
