 冷熱沖擊試驗的試驗目的和條件及對試驗箱的要求

 冷熱沖擊試驗用于電子電器零組件、自動化零部件、通訊組件、汽車配件、金屬、化學材料、塑膠等行業,測試其材料對高、低溫的反復抵拉力及產品于熱脹冷縮產出的化學變化或物理傷害,可確認產品的品質,從精密的IC到重機械的組件,無一不需要它的認同。

 

一、試驗目的

        確定設備(產品)在周圍大氣溫度急劇變化時的適應性。

二、試驗條件

2.1  試驗溫度:高溫為70℃;低溫為-55℃。

2.2  試驗溫度保持時間:1h或者直至試驗樣品達到溫度穩定,以時間長者為準。

2.3  轉換時間:不大于5min。

2.4  循環次數:3次。

三、對試驗箱(室)的要求

    本標準應用冷熱沖擊試驗箱(室)或采用高溫試驗箱(室)和低溫試驗箱(室)進行冷熱沖擊試驗,以提供試驗樣品經受周圍空氣溫度急劇發生變化的環境溫度。

3.1  高溫試驗箱(室)的要求,應符合GJB150.3-86《軍用設備環境試驗方法    高溫試驗》的第3章各條所規定的要求。

3.2  低溫試驗箱(室)的要求,應符合GJB150.4-86《軍用設備環境試驗方法    低溫試驗》的第3章各條所規定的要求。

3.3   冷熱沖擊試驗箱(室)提供高溫試驗部分和低溫試驗部分,應分別符合GJB150.3-86和GJB150.4-86的第3章各條所規定的要求。

3.4   試驗箱(室)的容積應保證在試驗樣品放入候補超過試驗溫度保持時間的10%就能使試驗箱(室)溫度達到GJB150.1-89中3.2條規定的試驗條件容差范圍之內。

四、恢復

        試驗樣品從試驗箱(室)內取出后,應在正常的試驗大氣條件下進行恢復,直至試驗樣品達到溫度穩定。
