高温试验箱与老化房有哪些区别

在长期与用户接触中，经常遇到用户对于高温试验箱与老化房(烧机房)等指标近似作用界限模糊的设备分不清的情况，在此做一个较系统的说明。老化房一般用于产品出厂前的老练筛选，挑除前期失效工件。多用于电工电子产品。高温试验箱用于试验样品做高温适应性试验及高温应力试验，也可当干燥箱用，但由于指标差异大，干燥箱不能替代高温试验箱。
In the long-term contact with users, users often encounter the ambiguous boundary between the high temperature test box and the aging room (burning machine room) and other indicators. Here, a more systematic description is given. Aging room is generally used for veteran screening of products before they leave the factory, and to pick out pre-failure workpieces. It is mostly used in electrical and electronic products. 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. 一、对应的产品标准
1. Corresponding Product Standards
高温试验箱现行执行标准GB/T11158-2008《高温试验箱技术条件》
Existing Implementation Standard GB/T11158-2008 "Technical Conditions for High Temperature Test Box"
老化房没有专用的产品标准，一般参照GB/T11158-2008《高温试验箱技术条件》执行
There is no special product standard for aging room, which is generally implemented with reference to GB/T11158-2008 "Technical Conditions for High Temperature Test Box"
二、指标的异同
Differences and Similarities of Indicators
高温试验箱
High temperature test box
温度波动度：≤1℃
Temperature fluctuation: <1 Temperature
温度梯度：≤2℃
Temperature gradient: <2 Temperature
温度偏差：±2℃
Temperature deviation: +2 C
老化房
Aging room
由于老化房没有产品标准，且使用温度不高，一般参照高温试验箱指标：
As there is no product standard for the aging room atand the temperature is not high, the index of high temperature test box is generally referred to:
温度波动度：≤1℃
Temperature fluctuation: <1 Temperature
温度均匀度：≤2℃(按GB/T11158-98的指标)
Temperature uniformity: <2 C (according to GB/T11158-98)
温度偏差：±2℃
Temperature deviation: +2 C
换气量：可调
Air exchange capacity: adjustable
三、结构
Three, structure
由于高温试验箱温场要求较高，一般采用层流设计。
The laminar flow design is generally adopted because of the high temperature test box temperature field requirements.
老化房一般要考虑试品架或试品车的情况。
Aging room should generally consider the situation of test rack or test car.
