Note:
1. The gas supply port of instrument is Φ6 mm PU Tubing;
2. Customers will need to provide gas supply;
3. The given temperature and humidity control ranges are independently valid.
Principle
Put the pre-conditioned specimen between the upper chamber and lower chamber, clamp it tightly. First evacuate the low-pressure chamber (lower chamber), and then the whole system. When the specified degree of vacuum is achieved, shut off the lower test chamber and feed test gas to the upper test chamber (high pressure chamber) until certain pressure is reached. Ensure that a constant differential pressure (adjustable) is maintained across the specimen. Hence under the gradient of differential pressure, the test gas permeates from the high-pressure side to the low-pressure side. By monitoring and measuring the pressure in the low-pressure side, a variety of barrier parameters of the tested specimen can be obtained.
Standards
This gas permeability tester conforms to the following standards:
ASTM D1434, ISO 2556, ISO 15105-1, GB/T 1038-2000, JIS K7126-1, YBB 00082003
