高溫試驗箱與老化房有哪些區別

在長期與用戶接觸中，經常遇到用戶對於高溫試驗箱與老化房(燒機房)等指標近似作用界限模糊的設備分不清的情況，在此做一個較系統的說明。老化房一般用於產品出廠前的老練篩選，挑除前期失效工件。多用於電工電子產品。高溫試驗箱用於試驗樣品做高溫適應性試驗及高溫應力試驗，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。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 u印花地坪sed 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、對應的產品標準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》Existing Implementation Standard GB/T11158-2008 "Technical Conditions环氧地坪 for High Temperature Test Box"老化房沒有專用的產品標準，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 aging room, which is generally implemented with reference to GB/T11158-2008 "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老化房Aging room由於老化房沒有產品標準，且使用溫度不高，一般參照高溫試驗箱指標：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: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，一般采用層流設計。The laminar flow design is generally adopted because of the high temperature test box temperature field requirements.老化房一般要考慮試品架或試品車的情況。Aging room should generally consider the situation of test rack or test car.
