Introduction
The ASTM F2622 standard is a critical test method for determining the oxygen gas transmission rate (OTR) through
plastic films and sheeting using various sensors. This standard is widely used in industries such as food packaging,
pharmaceuticals, and medical devices, where barrier properties are essential for product integrity and shelf life.
Scope and Application
ASTM F2622 applies to plastic films, laminates, and co-extruded sheets that may be used in packaging applications.
The test measures how much oxygen passes through a material over a specified time, helping manufacturers assess
material performance, quality control, and compliance with industry regulations.
Testing instrument:OTR-D3 Oxygen Permeability Tester
Test Principle
The method involves exposing a test specimen to an oxygen-rich environment on one side while measuring the oxygen
permeating through to the other side using electrochemical, coulometric, or other oxygen sensors. The transmission
rate is calculated based on the detected oxygen concentration, temperature, and humidity conditions.
Key Testing Parameters
Temperature & Humidity Control – Tests are conducted under controlled conditions (typically 23°C and 0% or 50% RH).
Sensor Selection – Different sensors (e.g., zirconia-based, optical) may be used based on sensitivity requirements.
Sample Preparation – Specimens must be free of defects and conditioned before testing.
Conclusion
ASTM F2622 is a vital standard for evaluating oxygen barrier properties in packaging materials. By following this method,
manufacturers can ensure product safety, extend shelf life, and meet compliance requirements.
