It was 2:00 AM when the alarm on Line 4 shrieked. A tray of glass vials, intended for a critical life-saving vaccine, had failed the preliminary vacuum decay test. The junior tech, Sarah, looked panicked. "The seals look fine, Elias. Maybe the machine is just out of calibration?" Elias didn't guess. He flipped to the section in Physical Test Methods
These methods rely on stochastic events (e.g., dye entering a leak only if the leak is oriented favorably). | | Cons | | :--- | :---
: Often considered the gold standard for validating a sterile barrier.
