ASTM D3078-02(2021)e1, "Standard Test Method for Determination of Leaks in Flexible Packaging by Bubble Emission," is the current protocol for detecting gross leaks using vacuum chamber bubble emission. The standard, which evaluates flexible packages with headspace gas, is available through authorized distributors. Purchase the standard directly from ASTM International ASTM International

| Component | Specification | |-----------|---------------| | Vacuum chamber | Transparent (glass, acrylic), sealable, with a rigid or flexible top | | Vacuum source | Vacuum pump or aspirator capable of achieving target vacuum | | Vacuum gauge | Accuracy ±2.5% of reading or ±2.5 mmHg, whichever is larger | | Immersion liquid | Clean water (default). Other liquids (e.g., water with wetting agent, oil) may be used if water wets package poorly. | | Timing device | ±1 second accuracy | | Pressure release valve | Slow venting to avoid agitation |
📌 : If your quality manual references the 2002 version, you are likely already compliant with the 2021 reapproval, as the fundamental methodology remains the same. How the Test is Performed
