Vacuum Decay vs. Bubble Leak Testing Under ASTM F2096 Method
Manufactured by Burhani Engineering Technology
Company Overview
Burhani Engineering Technology manufactures precision package integrity testing solutions for medical, pharmaceutical, and food packaging industries. Our systems support regulatory compliance, quality assurance, and validation through reliable and repeatable testing methods.
Product Introduction
Vacuum Decay and Bubble Leak Testing are two complementary methods for detecting leaks and seal defects in sealed packages. Both techniques can be applied under ASTM F2096 methodology to verify package integrity for medical devices, pharmaceutical products, and other sealed packaging applications.
Standard Compliance
The testing methods comply with ASTM F2096 – Standard Test Method for Detecting Gross Leaks in Packaging by Internal Pressurization (Bubble Test), ensuring accurate, standardized, and reproducible results for regulatory and quality control purposes.
Testing Method Overview
Vacuum Decay Testing:
Vacuum Decay is a quantitative, non-destructive method that measures pressure changes within a sealed test chamber. A leak is detected when vacuum loss exceeds predefined limits. This method is highly sensitive and suitable for detecting micro-leaks without using water or submersion.
Bubble Leak Testing:
Bubble Leak Testing is a visual method where the package is submerged in a water-filled chamber and internally pressurized. Leaks are identified by visible bubbles escaping from the package, providing a clear and immediate indication of gross leaks or seal defects.
Key Differences
-
Sensitivity: Vacuum Decay is more sensitive for detecting micro-leaks, while Bubble Leak Testing is ideal for gross leak detection.
-
Method: Vacuum Decay is non-destructive and dry; Bubble Leak Testing requires submersion in water.
-
Result Type: Vacuum Decay provides quantitative results; Bubble Leak Testing provides visual confirmation of leak location.
-
Applications: Vacuum Decay is suitable for sterile or high-throughput testing; Bubble Leak Testing is effective for visual validation and routine QC.
