In the packaging industry, maintaining the integrity of flexible packages is essential for product protection and compliance. ASTM F2095 provides a standardized approach to detect leaks in flexible packaging using pressure decay methods. This test ensures that packaging—especially in sectors like food, medical, and pharmaceuticals—meets stringent safety and quality expectations.
Pressure Decay Tester and Its Role in ASTM F2095
A key component of ASTM F2095 is the use of a pressure decay tester. This instrument measures the internal pressure loss in a sealed flexible package over time. A loss of pressure indicates a potential leak in the packaging material or seal. The pressure decay method is valued for its sensitivity and non-destructive nature, making it ideal for high-risk applications such as food packaging leak detection and sterile medical product validation.
Ten Tester szczelności i wytrzymałości uszczelnień LSST-01 by Instrumenty komórkowe is specifically designed for these applications. It provides precise pressurization, time-controlled testing, and reliable data recording, aligning perfectly with the procedural requirements of ASTM F2095.
ASTM F2095 Pressure Decay Method
Understanding ASTM F2095 Test Methods
Test Method A: Without Restraining Plates
This method is typically used when the package can naturally expand under pressure. It includes the following steps:
Pressurize the package to a preset value.
Stabilize the internal pressure.
Measure pressure decay over a fixed duration.
Determine leak presence based on the pressure drop.
This approach is ideal for assessing packaging where internal volume variations can occur, such as flexible food packaging or resealable pouches.

ASTM F2095 Leak Test Method B
Test Method B: With Restraining Plates
In scenarios where package expansion must be minimized to maintain consistent volume during testing, rigid restraining plates are used. This method is especially suitable for porous or irregularly shaped packages. The plates ensure that the test measures only pressure decay due to leaks, not due to volume fluctuations.
For both methods, the sample must be properly conditioned to match the testing environment—typically at 23 ± 2°C and 50 ± 5% RH—to avoid pressure fluctuations due to temperature differences.
Apparatus Requirements for ASTM F2095
To ensure compliance with ASTM F2095, your test system should include:
Ten Cell Instruments LSST-01 meets these requirements and offers user-friendly operation with automated cycles, reducing human error and increasing repeatability.
Applications in Food Packaging Leak Detection
W food packaging leak detection, ensuring seal integrity directly impacts product shelf life and consumer safety. ASTM F2095 enables manufacturers to verify package integrity without destroying the product. The LSST-01 offers critical support in identifying packaging defects before distribution, thus helping brands maintain trust and regulatory compliance.
Furthermore, flexible packaging used in frozen food, ready meals, or modified atmosphere packaging (MAP) greatly benefits from pressure decay testing, as even micro-leaks can compromise quality.
