2.Standard

3.Test principle:

1) Based on the vacuum chamber, vacuum that immersed in the water sample of inside and outside differential pressure, observations in the sample gas to escape, to determine the sample sealing performance;

2) Through the vacuum in vacuum chamber, make sample generation inside and outside differential pressure, the observation sample expansion and shape of the samples after the release of vacuum recovery, to determine the sealing performance for the sample.
