ASTM D3985 用库仑传感器测定塑料薄膜和薄板的氧气透过率的标准试验方法
标准名称
ASTM D3985 Standard Test Method for Oxygen Gas Transmission Rate Through Plastic Film and Sheeting Using a Coulometric Sensor
ASTM D3985 用库仑传感器测定塑料薄膜和薄板的氧气透过率的标准试验方法
适用范围
Scope：
This test method covers a procedure 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. It provides for the determination of (1) oxygen gas transmission rate (OTR), (2) the permeance of the film to oxygen gas (PO 2 ), and (3) oxygen permeability coefficient (P'O 2 ) in the case of homogeneous materials.
