Standards

YBB 00082003, GB/T 1038, ASTM D1434, ISO 2556, ISO 15105-1, JIS K7126-A

Gas Permeability Tester using the pressure difference method, the pre-treated sample is placed and clamped between the upper and lower test chambers. First, the low-pressure chamber (lower chamber) is vacuumed, then pumping the vacuum for the whole system, when the specified vacuum degree is reached, close the lower chamber, fill the high pressure chamber (upper chamber) with test gas at a certain pressure, and ensure that a constant pressure difference is formed on both sides of the sample (adjustable). In this way, the gas will permeate from the high-pressure side to the low-pressure side under the action of the pressure difference gradient. Through the monitoring and treatment of the internal pressure of the low pressure side, the barrier parameters of the tested samples are obtained. Fully comply with GB1038, ASTM D1434 and other standards.
