|Standard type:||ASTM D|
|Name:||ASTM D 3985|
|Designation:||Standard-Prüfverfahren für die Durchlässigkeit von Sauerstoffgas durch Plastikfolien unter Verwendung eines coulometrischen Sensors|
Tests of this standardOxygen transmission rate (OTR) of plastic films, laminates, coated papers, Alufoils, etc.
Coulombmetric (oxygen specific) carrier gas method Method (Ametek/ Mocon). Usually deviating from the standard as a double determination
Oxygen transmission rate (OTR) of packages, pouches, moulded parts, bottles, etc. (only suitable for barrier materials, see also "i")
The measurement is carried out using the coulommetric, oxygen-specific carrier gas method.
Attention: This is only suitable for packages with a good oxygen barrier. Materials with high permeation coefficients, such as PP, PE or PS cups cannot be measured because the permeation is too high.
