怎麽區別高溫老（lǎo）化房與（yǔ）高溫試驗箱？在長期與用戶接觸中，經常遇到用戶（hù）對於（yú）高溫試驗箱與高溫老化房（fáng）(燒機房)等指標近似作用界限模糊的設（shè）備分不清（qīng）的（de）情（qíng）況，在此做（zuò）了一個較係統的說明。希（xī）望對（duì）大家了（le）解高溫老化房和（hé）高溫（wēn）試驗箱有幫助啊。
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. 高溫試驗箱用於試驗樣品做高溫適應性試驗及高溫應（yīng）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（gāo）溫試驗箱。
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（chú）前（qián）期失（shī）效（xiào）工件。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（xiāng）技（jì）術條件》
Existing Implementation Standard GB/T11158-2008 "Technical Conditions for High Temperature Test Box"
高溫老化房（fáng）沒有專用的（de）產品標準，一般參照GB/T11158-2008《高溫試驗箱技術條件》執行
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（wēn）試驗（yàn）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（chà）：±2℃
Temperature deviation: +2 C
高溫老化房
High temperature aging room
由於高溫老化房沒有產品標準，且使用溫度不高，一（yī）般參照高溫試驗（yàn）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（wēn）度波動度：≤1℃
Temperature fluctuation: <1 Temperature
溫度均（jun1）勻度：≤2℃(按GB/T11158-98的指（zhǐ）標)
Temperature uniformity: <2 C (according to GB/T11158-98)
溫度偏差：±2℃
Temperature deviation: +2 C
換氣（qì）量：可調
Air exchange capacity: adjustable
三（sān）、結構
Three, structure
由於高溫試驗箱溫場要求較高，一般（bān）采用層流設計。
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架或試品車的情況。
High temperature aging room should generally consider the situation of test rack or test car.
