PLASTICS – FILM AND SHEETING – DETERMINATION OF OXYGEN GAS TRANSMISSION RATE USING A COULOMETRIC SENSOR
This Malaysian Standard prescribes method for determination of the steady-state rate of transmission of oxygen gas through plastics in the form of film, sheeting, laminates, coextrusions, or plastic-coated papers or fabrics.The method is used to determine:
a) oxygen gas transmission rate (O2GTR);
b) the permeance of the film to oxygen gas (PO2);and
c) oxygen permeability coefficient (PO2) in the case of homogeneous materials.
