冷熱沖擊試驗箱也是我們常說的高低溫沖擊試驗箱，主要用于對于復合(he)材(cai)料在(zai)連續高溫(wen)或低(di)溫(wen)的沖擊(ji)環境下(xia)的忍耐(nai)度測試(shi)，以測試(shi)材(cai)料在(zai)短時(shi)間內受到冷熱(re)沖擊(ji)下(xia)的物理傷害及化(hua)學(xue)變化(hua)。那么(me)在(zai)測試(shi)之(zhi)后(hou)要怎么(me)校準試(shi)驗箱(xiang)的溫(wen)度恢復時(shi)間呢？

 按(an)規定位置(zhi)安(an)裝溫(wen)(wen)(wen)度丈量傳感(gan)器(qi)(qi)，將高溫(wen)(wen)(wen)箱和低溫(wen)(wen)(wen)箱的(de)溫(wen)(wen)(wen)度控制器(qi)(qi)分別調理到所要(yao)求的(de)標準溫(wen)(wen)(wen)度上；

 分別使箱體(ti)升(sheng)溫(wen)(wen)和(he)降溫(wen)(wen)，自冷熱(re)沖擊箱進入控溫(wen)(wen)狀態(tai)后(hou)穩定30min或按(an)產品技術條件要(yao)求穩定相(xiang)應的(de)時間，記錄丈量點(dian)的(de)溫(wen)(wen)度值；

 冷熱沖擊箱將檢驗負載置入高溫裝備中，按(an)產品技術條件要求或有(you)關標(biao)準的(de)規定選擇相應的(de)保持時間；

 選擇冷熱沖擊(ji)箱的(de)轉(zhuan)換(huan)時間(jian)，然后將(jiang)檢(jian)驗(yan)負(fu)載由高(gao)溫(wen)(wen)裝(zhuang)(zhuang)備轉(zhuan)入(ru)低溫(wen)(wen)裝(zhuang)(zhuang)備，注意視(shi)察和(he)記錄(lu)丈(zhang)量點的(de)溫(wen)(wen)度；再按(an)相同的(de)方法進(jin)行檢(jian)驗(yan)負(fu)載由低溫(wen)(wen)裝(zhuang)(zhuang)備向高(gao)溫(wen)(wen)裝(zhuang)(zhuang)備的(de)相反轉(zhuan)換(huan)，注意視(shi)察和(he)記錄(lu)丈(zhang)量點的(de)溫(wen)(wen)度；

分別(bie)記錄檢驗冷熱沖擊(ji)箱負載(zai)從高(gao)(gao)溫(wen)(或低(di)溫(wen))裝(zhuang)備(bei)(bei)轉換到(dao)低(di)溫(wen)(或高(gao)(gao)溫(wen))裝(zhuang)備(bei)(bei)后至裝(zhuang)備(bei)(bei)丈量點溫(wen)度(du)恢復到(dao)檢驗負載(zai)放入之前的(de)溫(wen)度(du)狀(zhuang)態所需要的(de)最短時間。
