Absolute pressure decay leak tester AUTO GBM-D1

pressurehigh-pressureleakage

Instrument introduction
GBM-D1 intelligent sealing performance tester pressurizes samples to evaluate seal strength and package integrity. It supports burst, leakage (pressure decay), creep and bubble methods and accepts flexible, rigid, porous and laminated aluminum packaging used in food, pharmaceuticals and industrial applications. The unit offers multiple test modes, accessory options and compliance with relevant ASTM, ISO and GB/YY standards.

Test principle
The tester applies controlled air pressure to the sealed sample either until burst or to a specified pressure level to assess sealing performance. Tests can quantify burst pressure, pressure decay, time-to-failure under sustained pressure and visible leaks (bubbles). Results are reported with test pressure, hold time, package location and leak position.

Test method

• Burst test: Pressure is increased continuously until the package ruptures. (Compliant with ASTM F1140, ASTM F2054, YY/T 0681.3, YY/T 0681.9)
• Leakage test: Inflate to a preset pressure and hold for the test duration, then perform pressure decay/leakage measurement. Testing can be unconstrained or use a restraining plate. (Compliant with ASTM F2095, ISO 11607-1)
• Creep test: Maintain a constant pressure near burst limit to evaluate seal performance over time; optional creep-to-failure mode available. (ASTM F1140, YY/T 0681.3)
• Bubble test: Submerge package in water, pressurize to a set pressure and observe for bubble emission during the hold period. (ASTM F2096, YY/T 0681.5)
