 冷热冲击试验的试验目的和条件及对试验箱的要求

 冷热冲击试验用于电子电器零组件、自动化零部件、通讯组件、汽车配件、金属、化学材料、塑胶等行业,测试其材料对高、低温的反复抵拉力及产品于热胀冷缩产出的化学变化或物理伤害,可确认产品的品质,从精密的IC到重机械的组件,无一不需要它的认同。

 

一、试验目的

        确定设备(产品)在周围大气温度急剧变化时的适应性。

二、试验条件

2.1  试验温度:高温为70℃;低温为-55℃。

2.2  试验温度保持时间:1h或者直至试验样品达到温度稳定,以时间长者为准。

2.3  转换时间:不大于5min。

2.4  循环次数:3次。

三、对试验箱(室)的要求

    本标准应用冷热冲击试验箱(室)或采用高温试验箱(室)和低温试验箱(室)进行冷热冲击试验,以提供试验样品经受周围空气温度急剧发生变化的环境温度。

3.1  高温试验箱(室)的要求,应符合GJB150.3-86《军用设备环境试验方法    高温试验》的第3章各条所规定的要求。

3.2  低温试验箱(室)的要求,应符合GJB150.4-86《军用设备环境试验方法    低温试验》的第3章各条所规定的要求。

3.3   冷热冲击试验箱(室)提供高温试验部分和低温试验部分,应分别符合GJB150.3-86和GJB150.4-86的第3章各条所规定的要求。

3.4   试验箱(室)的容积应保证在试验样品放入候补超过试验温度保持时间的10%就能使试验箱(室)温度达到GJB150.1-89中3.2条规定的试验条件容差范围之内。

四、恢复

        试验样品从试验箱(室)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。
