ASTM F2096
Gross Bubble Leak Testing

ASTM F2096 is a widely recognized standard test method used for detecting gross leaks in packaging through internal pressurization, commonly known as the bubble leak test. This test is critical in quality assurance protocols for medical devices, pharmaceuticals, and other high-integrity packaging sectors.

The method involves submerging a package under water and injecting air inside. A visible stream of bubbles indicates a leak path or seal failure. Its ease of implementation, visual clarity, and ability to handle various packaging types make it an industry-favored option.

At Cell Instruments, we offer high-performance testing solutions tailored for ASTM F2096, including our GLT-01 Gross Leak Bubble Tester, engineered for sensitive and accurate bubble emission tests.

Overview of the Bubble Leak Test Procedure

Bubble Emission Test for Package Integrity

Der bubble emission test under ASTM F2096 is designed to simulate real-world failure scenarios in packaging. It evaluates defects such as seal failures, pinholes, or material cracks, ensuring product sterility and safety.

Two primary procedures are outlined:

Test Method A for nonporous packaging
Test Method B for porous materials (e.g., Tyvek®)

The typical test steps include:

Creating a controlled puncture in the package.
Submerging it under approximately 25.4 mm of water.
Injecting air at a predetermined pressure.
Observing for bubble streams indicating leaks.

Das gross leak detection method is destructive and ideal for design validation, quality control, and compliance testing.

Gross Leak Bubble Tester: Role and Importance

To perform ASTM F2096 effectively, a gross leak bubble tester is essential. This apparatus consists of:

A pressure delivery system with a bleed-off control valve
A transparent water immersion tank
A device for puncturing and monitoring internal pressure

Using a properly calibrated tester ensures repeatable and accurate leak detection, reducing false positives or overlooked defects.

Zellinstrumente’ GLT-01 Gross Leak Tester is purpose-built for this standard. It supports:

Precise low-pressure control (0–50 mbar)
Transparent observation chamber for enhanced visibility
Customizable fixtures for diverse package formats

This makes it an ideal solution for manufacturers in medical, food, and pharmaceutical industries who must comply with strict packaging integrity standards.

Application of ASTM F2096 in Industry

Why ASTM F2096 Matters

Ensuring package integrity is essential for:

Sterility assurance in medical packaging
Contamination control in food packaging
Shelf-life stability for pharmaceuticals

This standard supports regulatory and customer expectations by providing a visual and straightforward integrity test with quantifiable sensitivity. According to the standard, it can detect leaks as small as 250 μm with 81% probability, making it suitable for high-risk applications.

Manufacturers who adopt ASTM F2096 as a routine QC method demonstrate commitment to product safety, regulatory compliance, Und brand trust.
