大型高低温冲击试验箱操作分为五部走:预处理、初始检测、试验、恢复、最后检测。下面恒泰丰科和大家一起分享一下详细流程内容:

1.预处理:将被测样品放置在正常的试验大气条件下,直至达到温度稳定。

2.初始检测:将被测样品与标准要求对照,符合要求后直接放入高低温冲击试验箱内即可。

3.大型高低温冲击试验箱试验:

1)试验样品应按标准要求放置在试验箱内,并将试验箱()内温度升到指定点,保持一定的时间至试验样品达到温度稳定,以时间长都为准。

2)高温阶段结束后,在5min内将试验样品转换到已调节到-55的低温试验箱()内,保持1h或者直至试验样品达到温度稳定,以时间长都为准。

3)低温阶段结束后,在5min内将试验样品转换到已调节到70的高温试验箱()内,保持1h或者直至试验样品达到温度稳定,以时间长都为准。

4)重复上述实验方法,以完成三个循环周期。根据样件大小与空间大小,时间可能会略有误差。

4. 恢复:试验样品从试验箱内取出后,应在正常的试验大气条件下进行恢复,直至试验样品达到温度稳定。

5.大型高低温冲击试验箱最后检测:对照标准中的受损程度及其它方法进行检测结果评定。



高低温冲击试验箱同类及其它产品有:三箱型高低温冲击箱、移动式高低温冲击箱、HAST加速试验箱、台式PCT老化试验箱、紫外线老化试验箱等。
