ASTM F2054 is a critical standard test method developed by ASTM International that evaluates the burst resistance of 

flexible package seals through internal air pressurization while using restraining plates. This method provides 

manufacturers and quality control professionals with a reliable means to assess package integrity, which is essential

 for ensuring product protection, shelf life, and consumer safety.

Scope and Purpose

The ASTM F2054 standard specifies the procedure for determining the minimum burst pressure of flexible package 

seals when subjected to internal air pressure. The test is performed while the package is constrained between rigid

 plates, simulating real-world conditions where packages often rest against other products or container walls during 

storage and transportation.

The test requires specific equipment:

Pressure system: Capable of delivering controlled internal air pressure to the test specimen at a specified rate

Restraining plates: Rigid, flat plates with a central opening that allows package expansion while limiting deformation

Pressure measurement device: Accurate to ±1% of the measured value

Specimen mounting fixture: To securely hold the package between the restraining plates

The standard specifies that restraining plates should have a minimum thickness of 6 mm (0.25 in) and an opening 

diameter appropriate for the package size being tested.

Testing instrument：LT-03A Leak and seal strength tester

Test Procedure

Specimen preparation: Packages should be conditioned at 23±2°C (73.4±3.6°F) and 50±5% relative humidity for at 

least 24 hours before testing.

Mounting: The package is placed between the restraining plates, ensuring the seal area to be tested is properly aligned 

with the plate opening.

Pressurization: Air is introduced into the package at a constant rate of 10 kPa/s (1.45 psi/s) or other specified rate until 

failure occurs.

Failure detection: The test continues until the package seal bursts or the package material fails.

Data recording: The maximum pressure achieved before failure is recorded as the burst strength.

Interpretation of Results

The burst pressure provides quantitative data about package seal strength. Higher values indicate more robust seals

 capable of withstanding greater internal pressures. The standard recommends testing multiple samples (typically 10 

or more) to establish statistically significant results.

Applications and Industries

ASTM F2054 is widely used across various industries:

Medical device packaging: Ensuring sterile barrier integrity

Food packaging: Maintaining product freshness and preventing contamination

Pharmaceutical packaging: Protecting drug products from environmental factors

Consumer goods: Verifying package durability during distribution

Conclusion

ASTM F2054 provides an essential methodology for evaluating the burst resistance of flexible package seals under 

controlled conditions. By implementing this standardized test, manufacturers can improve package design, ensure 

product protection, and maintain consistent quality in their packaging operations. As packaging technologies evolve, 

standards like ASTM F2054 continue to play a vital role in advancing packaging performance and reliability.
