砂(sha)塵試驗(yan)(yan)(yan)(yan)箱(xiang)又名防(fang)(fang)塵試驗(yan)(yan)(yan)(yan)機、砂(sha)塵測試箱(xiang)、防(fang)(fang)塵實驗(yan)(yan)(yan)(yan)機、耐塵實驗(yan)(yan)(yan)(yan)機、外(wai)殼防(fang)(fang)塵試驗(yan)(yan)(yan)(yan)箱(xiang)主要用(yong)于(yu)對電(dian)子、家用(yong)電(dian)器、電(dian)工(gong)、汽(qi)車(che)燈具、汽(qi)車(che)配件(jian)(jian)、摩托車(che)、化工(gong)及其他(ta)零部件(jian)(jian)及材(cai)料(liao)進行防(fang)(fang)塵試驗(yan)(yan)(yan)(yan)，從而檢測產(chan)品的外(wai)殼密封性能，滿足GB4208-93外(wai)殼防(fang)(fang)護等級IP5X/IP6X防(fang)(fang)塵試驗(yan)(yan)(yan)(yan)。砂(sha)塵試驗(yan)(yan)(yan)(yan)箱(xiang)主要是模擬沙塵暴天(tian)氣對鎖具、汽(qi)摩零部件(jian)(jian)、密封件(jian)(jian)、電(dian)力儀表(biao)燈產(chan)品所造成(cheng)的破壞。

  砂塵試驗箱用以確定設備防御塵埃料滲透效應的能力。試驗程序如下：
  沙塵試驗箱初始檢測：按GJB150.1－86中3.5.2條款要求進行。
  試驗樣品在試驗箱(室)中的安裝：按GJB150.1－86中3.5.3款和有關標準規定的安裝方向進行，應使試驗樣品的zui關鍵、zui薄弱的表面朝向砂塵氣流方向。如有規定，試驗時可以按規定改變試驗樣品的方向。
  防塵試驗箱試驗：控制試驗箱(室)內溫度為23℃，相對濕度小于30%，調節風速為8.9±1.2m/s，調整塵粒辦輸入量，使吹粉塵濃度為1.06±7m/ s3，保持上述條件6h。停止輸入塵粒，并將風速調節到1.5±1m/s，試驗箱(室)內溫度升高到60℃或設備zui高工作溫度，升溫速率小于10℃/min，保持上述條件16h或試驗樣品達到溫度穩定所需的時間。保持試驗箱(室)內溫度為60℃或設備zui高工作溫度,調節風速為8.9±1.2m/s,繼續輸入塵粒，控制吹粉塵濃度為10.6±7g/m3，如無其它規定，保持上述條件6h。
  砂塵防護試驗箱試驗恢復：試驗箱(室)停止工作,使試驗箱(室)內條件恢復到正常的試驗大氣條件。取出試驗樣品，抖掉或用刷子掉積聚在試驗樣品上的塵粒，注意避免其他砂塵再落到試驗樣品上，不能用吹風機或真空吸塵器清除試驗樣品上的塵粒。
  試驗zui后檢測：按GJB150.1－3.5.7款要求進行。在外觀檢查時，應注意檢查試驗樣品的軸承、油脂密封處、潤滑部位等是否有塵粒積聚、積聚部位和積聚量。然后，按GJB150、1－86中3.5.8款要求評定試驗結果。
