Test Qa and Qc are rough inspections, to observe the bubbles emerging from the leak. Test Qd is to observe the leakage of liquid, under heating conditions. Test Qy is to make the gas pass through the leak and enter the test box, under reduced pressure, then measure the performance change of the test box. Test Qk, Qm is to use tracer gas to detect small leaks. Test Qf, Ql is to make liquid enter it through the leak, under pressurized conditions, then measure its performance changes. This Part is suitable for testing the sealing performance of various electrical and electronic products. It is also suitable for testing the sealing performance of other sealing parts.
