高溫試驗箱用于試驗樣品做高溫適應性試驗及高溫應力試驗，也可當干燥箱用，但由于指標差異大，干燥箱不能替代高溫試驗箱。高溫老化房一般用于產(chǎn)品出廠前的老練篩選，挑除前期失效工件。多用于電工電子產(chǎn)品。在長期與用戶接觸中，經(jīng)常遇到用戶對于高溫試驗箱與高溫老化房(燒機房)等指標近似作用界限模糊的設(shè)備分不清的情況，在此做了一個較系統(tǒng)的說明。希望對大家了解高溫老化房和高溫試驗箱有幫助啊。
The high temperature test box can be used for high temperature adaptability test and high temperature stress test of test samples, and also for drying box. However, because of the great difference of indexes, the drying box can not replace the high temperature test box. The high temperature aging room is generally used for the veteran screening of products before they leave the factory, and for the removal of pre-failure workpieces. It is mostly used in electrical and electronic products. In the long-term contact with users, users often encounter ambiguous boundary between high temperature test box and high temperature aging room (burning machine room) and other indicators. Here, a more systematic explanation is made. Hope to help you understand the high temperature aging room and high temperature test box. 一、對應的產(chǎn)品標準
1. Corresponding Product Standards

高溫試驗箱現(xiàn)行執(zhí)行標準GB/T11158-2008《高溫試驗箱技術(shù)條件》
Existing Implementation Standard GB/T11158-2008 "Technical Conditions for High Temperature Test Box"

高溫老化房沒有專用的產(chǎn)品標準，一般參照GB/T11158-2008《高溫試驗箱技術(shù)條件》執(zhí)行
There is no special product standard for high temperature aging room, which is generally implemented with reference to GB/T 1158-2008 "Technical Conditions for High Temperature Test Box"

二、指標的異同
Differences and Similarities of Indicators

高溫試驗箱
High temperature test box

溫度波動度：≤1℃
Temperature fluctuation: <1 Temperature

溫度梯度：≤2℃
Temperature gradient: <2 Temperature

溫度偏差：±2℃
Temperature deviation: +2 C

高溫老化房
High temperature aging room

由于高溫老化房沒有產(chǎn)品標準，且使用溫度不高，一般參照高溫試驗箱指標：
Because there is no product standard for high temperature aging room and the use temperature is not high, generally refer to the index of high temperature test box:

溫度波動度：≤1℃
Temperature fluctuation: <1 Temperature

溫度均勻度：≤2℃(按GB/T11158-98的指標)
Temperature uniformity: <2 C (according to GB/T11158-98)

溫度偏差：±2℃
Temperature deviation: +2 C

換氣量：可調(diào)
Air exchange capacity: adjustable

三、結(jié)構(gòu)
Three, structure

由于高溫試驗箱溫場要求較高，一般采用層流設(shè)計。
The laminar flow design is generally adopted because of the high temperature test box temperature field requirements.

高溫老化房一般要考慮試品架或試品車的情況。
High temperature aging room should generally consider the situation of test rack or test car
