Oxygen Permeation of Flexible Barrier Materials Using a Coulometric Sensor ASTM D3985, ISO 15105
Oxygen Transmission Rate Scope:
Determine oxygen transmission rate (OTR) of flexible barrier materials used in packaging or industrial applications. Key factors to understand material permeation include thickness of the material and environmental factors such as relative humidity and temperature.
ASTM D3985 Test Procedure:
At a selected temperature and humidity, a barrier film is sealed between a chamber containing oxygen and a chamber void of oxygen. A coulometric sensor measures the oxygen that is transmitted through the material.
Typical Test Area: 50cm2
Data:
Oxygen Transmission Rate (OTR) mol/(m2•s)
