Test rationale试验原理:

Vacuumize the vacuum chamber, such that the test piece dipped in the water could generate differential pressure inside and outside, observe the escape of the air within the test piece, so as to determine the seal performance of the test piece. Vacuumize the vacuum chamber, such that the test piece could generate differential pressure inside and outside, observe the swell of the test piece and the shape recovery of the test piece after releasing the vacuum, so as to determine the seal performance of the test piece.

通过对真空室抽真空，使浸在水中的试样产生内外压差，观测试样内气体外逸情况，以此判定试样的密封性能；通过对真空室抽真空，使试样产生内外压差，观测试样膨胀及释放真空后试样形状恢复情况，以此判定试样的密封性能。
