The ASTM D3078 procedure requires a vacuum chamber, a transparent lid (or a chamber with viewing windows), and a suitable immersion fluid (typically water). The general procedure is as follows:
| Method | Sensitivity | Quantifiable? | Destructive? | Cost | Best For | |--------|-------------|---------------|--------------|------|-----------| | | ~50–100 µm | No | No | $ | QC gross leak screen | | ASTM F2096 (internal pressurization bubble) | ~50–100 µm | No | Yes (often) | $ | Flexible pouches with headspace | | ASTM F2338 (vacuum decay) | ~5–15 µm | Yes | No | $$ | Pharma, medical devices | | ASTM F2391 (high voltage leak test) | ~10–50 µm | No | No | $$$ | Non-porous, conductive packages | | Helium leak test (ASTM E498) | <1 µm | Yes | No | $$$$ | High-integrity seals | astm d3078
In the world of medical devices, pharmaceuticals, and food packaging, sterility is non-negotiable. A microscopic pinhole in a flexible package can render a lifesaving device useless or turn a sterile drug into a health hazard. To combat this, manufacturers rely on standardized testing methods to validate their packaging processes. The ASTM D3078 procedure requires a vacuum chamber,
However, ASTM D3078 is designed for detecting . It is not intended to detect ultra-fine leaks that might require trace gas detection (like Helium leak testing) or high-voltage leak detection. However, ASTM D3078 is designed for detecting
