高低溫交變濕(shi)熱試驗(yan)箱如何選擇(ze)可(ke)靠的(de)
高低(di)溫(wen)交變試驗箱環境及可靠性(xing)試驗設(she)備的選擇應遵循(xun)以下五條基本原(yuan)則(ze)!
1、環(huan)(huan)境(jing)(jing)條(tiao)(tiao)件(jian)的再現(xian)性(xing)在一定的容(rong)差范圍之內，人(ren)們(men)*可以正(zheng)確而近似(si)地模擬(ni)工(gong)程產(chan)品在使(shi)用(yong)、貯存、運輸等(deng)過程中(zhong)(zhong)所經受的外界環(huan)(huan)境(jing)(jing)條(tiao)(tiao)件(jian)，根據不(bu)同類(lei)型(xing)產(chan)品所規定的高(gao)溫(wen)、低溫(wen)的試(shi)(shi)驗(yan)量值、試(shi)(shi)驗(yan)時間，同時也應滿足試(shi)(shi)驗(yan)規范中(zhong)(zhong)對溫(wen)度(du)場的均勻性(xing)和溫(wen)度(du)控制精(jing)度(du)的要求。只有這樣，才能保(bao)證在環(huan)(huan)境(jing)(jing)試(shi)(shi)驗(yan)中(zhong)(zhong)環(huan)(huan)境(jing)(jing)條(tiao)(tiao)件(jian)的再現(xian)性(xing)。
2、環(huan)(huan)(huan)境(jing)條(tiao)件的可(ke)(ke)(ke)重復性(xing)一(yi)臺環(huan)(huan)(huan)境(jing)試(shi)(shi)(shi)(shi)驗(yan)設備(bei)(bei)可(ke)(ke)(ke)能用于(yu)同(tong)一(yi)類型產(chan)(chan)品的多次試(shi)(shi)(shi)(shi)驗(yan)，而(er)一(yi)臺被(bei)試(shi)(shi)(shi)(shi)的工(gong)程(cheng)產(chan)(chan)品也可(ke)(ke)(ke)能在不同(tong)的環(huan)(huan)(huan)境(jing)試(shi)(shi)(shi)(shi)驗(yan)設備(bei)(bei)中進(jin)行試(shi)(shi)(shi)(shi)驗(yan)，為(wei)了保證同(tong)一(yi)臺產(chan)(chan)品在同(tong)一(yi)試(shi)(shi)(shi)(shi)驗(yan)規范所(suo)規定的環(huan)(huan)(huan)境(jing)試(shi)(shi)(shi)(shi)驗(yan)條(tiao)件下所(suo)得試(shi)(shi)(shi)(shi)驗(yan)結果的可(ke)(ke)(ke)比較性(xing)，必然要(yao)求(qiu)環(huan)(huan)(huan)境(jing)試(shi)(shi)(shi)(shi)驗(yan)設備(bei)(bei)所(suo)提(ti)供(gong)的環(huan)(huan)(huan)境(jing)條(tiao)件具有可(ke)(ke)(ke)重復性(xing)。并(bing)且環(huan)(huan)(huan)境(jing)試(shi)(shi)(shi)(shi)驗(yan)設備(bei)(bei)所(suo)提(ti)供(gong)環(huan)(huan)(huan)境(jing)條(tiao)件的可(ke)(ke)(ke)重復性(xing)是由國(guo)(guo)家計量檢定部門(men)依據國(guo)(guo)家技(ji)術監督(du)機(ji)構(gou)所(suo)制(zhi)定的檢定規程(cheng)檢定合格后(hou)提(ti)供(gong)保證。
3、環境(jing)條件(jian)(jian)參數(shu)的(de)可測(ce)控(kong)性任何一(yi)臺環境(jing)試驗設備(bei)所提(ti)供(gong)的(de)環境(jing)條件(jian)(jian)是可觀測(ce)的(de)和可控(kong)制的(de)。
4、環境(jing)試驗(yan)(yan)(yan)條件的(de)排(pai)(pai)它(ta)性：每一次進行(xing)的(de)環境(jing)或可靠性試驗(yan)(yan)(yan)，對(dui)環境(jing)因(yin)素的(de)類別、量值及容差都有嚴格的(de)規(gui)定，并排(pai)(pai)除非試驗(yan)(yan)(yan)所(suo)需的(de)環境(jing)因(yin)素，以便在試驗(yan)(yan)(yan)中或試驗(yan)(yan)(yan)結束后判(pan)斷和分析產品失效與(yu)故障模式時(shi)，提供(gong)確切的(de)依據，故要求環境(jing)試驗(yan)(yan)(yan)設備除提供(gong)所(suo)規(gui)定的(de)環境(jing)條件外，不允許對(dui)被試產品附(fu)加其(qi)它(ta)的(de)環境(jing)應(ying)力干擾。
