怎麽區別高溫老化房與高溫試驗箱？在長（zhǎng）期與用（yòng）戶（hù）接觸中，經（jīng）常（cháng）遇到用戶對於高溫（wēn）試（shì）驗箱（xiāng）與（yǔ）高溫老化房(燒機（jī）房)等（děng）指標近似作用界限模糊的設（shè）備分不清的情（qíng）況，在（zài）此做了（le）一個較係統（tǒng）的說明。希（xī）望對大家了解高溫老（lǎo）化房和高溫試驗（yàn）箱有幫助啊。
How to distinguish high temperature aging room from high temperature test box? 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. 高溫試驗箱用於試（shì）驗樣品（pǐn）做高溫適應性試驗及（jí）高溫應力（lì）試驗，也可當幹燥箱用，但由於指標差異大，幹燥箱不能替代高溫試驗箱（xiāng）。
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.
高溫老化房一般用於產品出廠前的老練篩選，挑除前期失效工（gōng）件（jiàn）。多用於電工電子產品。
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.
一、對（duì）應（yīng）的產品標準
1. Corresponding Product Standards
高溫試驗箱現行執行標準GB/T11158-2008《高溫試驗箱技術條件（jiàn）》
Existing Implementation Standard GB/T11158-2008 "Technical Conditions for High Temperature Test Box"
高溫老化房沒有（yǒu）專用的產品標（biāo）準（zhǔn），一般參照GB/T11158-2008《高（gāo）溫（wēn）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（gāo）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
由於高溫老化房沒有（yǒu）產（chǎn）品標（biāo）準，且使用溫度不高，一般參照高溫試（shì）驗箱（xiāng）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
Air exchange capacity: adjustable
三、結構
Three, structure
由於高溫試驗箱溫場要求較高，一般采用（yòng）層流設計。
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（pǐn）架或試品車的情況。
High temperature aging room should generally consider the situation of test rack or test car.
