PackageIntegrityLeakTestQualityChecker

Package Integrity & Leak Test Quality Checker — Control of Package Integrity (CCIT)

ℹ️  Utility checks compliance of leak test results with USP <1207> requirements:
   • Measured leak value must be strictly below the established Reject Limit.
   • Supported methods: HVLD (High Voltage Leak Detection), Vacuum Decay, Pressure Decay.

⚠️  CRITICAL: Exceeding the limit means breach of package barrier function!
   Product is considered non-sterile and must be immediately quarantined.

Usage:
 PackageIntegrityLeakTestQualityChecker.exe                            → demo mode (console output)
 PackageIntegrityLeakTestQualityChecker.exe input.csv output.json      → evaluate your data

Input format:
BatchNumber,MeasuredLeakValue,RejectLimit,TestMethod

Example:
 CCIT-VIAL-2026-001,1.5,5.0,HVLD

— WHY IS THIS NEEDED?
Container Closure Integrity Testing (CCIT) replaces traditional dye immersion testing.
• USP <1207> recommends use of deterministic physicochemical methods (HVLD, vacuum decay).
• Allows detection of microscopic defects (cracks, seal failures, cap defects) invisible to visual inspection.
• Non-destructive method allows product retention if test is passed.
• Automation eliminates risk of missing defective units.

⚠️  CRITICAL:
• Reject Limit must be established based on method validation and critical defect size.
• For HVLD: high conductivity may indicate electrolyte outside vial (leak) or electrode contamination.
• For Vacuum/Pressure Decay: pressure stability over time is key indicator.
• Instrument calibration must be performed using artificial defects of known size.

Key features:
• Verification of measured parameters against safety limits.
• Support for various leak detection technologies.
• Generation of clear PASS/FAIL status for quality management systems.

Critical parameters:
• Leak Value: < Reject Limit

💡 Usage tips:
1. Regularly clean contact surfaces (for HVLD) or chamber seals (for vacuum methods).
2. Check instrument with "zero" sample (dummy) before starting series.
3. Account for ambient temperature and humidity influence on sensor sensitivity.
4. For highly conductive products, use pressure-based methods rather than current-based.
5. Save signal graphs (if available) for investigating questionable results.

⚠️ Note: Unlike Dye Ingress test, which is probabilistic and destructive, these methods are deterministic, quantitative, and allow 100% automated inline control.
