It is particularly effective for identifying issues such as: Weak or uneven heat seals Pinholes or punctures caused by handling Misaligned closures and material defects in film Key Sensitivity Limits:
ASTM D3078-02(2021) outlines a vacuum-based bubble emission test to identify gross leaks in flexible packaging, specifically targeting seals in pouches and blister packs. The procedure requires submerging packages in a vacuum chamber, with limitations noted for small leaks and reliance on operator interpretation. For more details, visit AMETEK MOCON
Part 3: Apparatus Requirements
| 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 |
Optional: A transparent top plate for observing packages that float. astm d3078 pdf 2021

Alternatives to ASTM D3078 for Leak Testing
If you cannot use the bubble method, consider these ASTM alternatives: Summary Table: Key Specs at a Glance |
| Standard | Method | Best for | |----------|--------|----------| | ASTM F2338 | Vacuum decay | Non-porous, micro-leaks, automated | | ASTM F1929 | Dye penetration | Porous/non-porous seals, colored dye | | ASTM F3039 | Laser-based gas leak | High sensitivity, non-destructive | | ASTM F2095 | Pressure decay | Rigid or semi-rigid packages |
Note: None of these are direct substitutes; selection depends on your package material and sensitivity requirement.
Step 5: Observation
- Start timing once target vacuum is reached.
- Observe for steady stream of bubbles.
- Do not count:
- Bubbles from trapped air under seals or folds (usually brief)
- Bubbles from package surface outgassing
- Single bubbles without repetition
