Testing Principle of Gas Permeability Tester
Based on the differential pressure testing principle, the pre-treated sample is placed and clamped between the upper and lower test chambers. The lower chamber (low-pressure chamber) is vacuumed, followed by evacuating the entire system. Once the desired vacuum level is reached, the lower chamber is sealed, and the upper chamber (high-pressure chamber) is filled with the test gas at a specified pressure, creating a constant (adjustable) pressure differential across the sample. The gas permeates from the high-pressure side to the low-pressure side due to the pressure gradient. By monitoring the pressure in the low-pressure side, the barrier properties of the sample are determined.
Reference Standards:
GB/T 1038, ASTM D1434, ISO 2556, ISO 15105-1, JIS K7126-A, YBB 00082003, etc.
