Fundamentals of Vacuum Decay Testing

Vacuum decay testing is a non-destructive, quantitative leak test method used to detect leaks in packaging and ensure container closure integrity (CCI). This technique relies on creating a vacuum within a sealed test chamber and monitoring pressure changes over time to identify any leaks.

Principles of Pressure Differential in Leak Detection

Vacuum decay testing operates on the principle of pressure differential to detect leaks. Here’s how it works:

  • The package is placed in a tightly fitted chamber, which is then evacuated to a predetermined vacuum level.
  • After reaching the desired vacuum, the vacuum source is isolated, and the pressure inside the chamber is monitored for a set period.
  • If the package is intact, the pressure inside the chamber remains stable.
  • Any rise in pressure indicates a leak in the package, compromising its integrity.

Key Components of a Vacuum Decay Testing System

A vacuum decay testing system consists of several crucial components that work together to ensure accurate and reliable leak detection:

Test Chamber Design and Functionality

  • The test chamber is designed to accommodate various package sizes and shapes.
  • It features a tight-fitting seal to maintain the vacuum during testing.
  • Some chambers include adjustable fixtures to hold packages securely in place.

Vacuum Pump Specifications and Operation
