GB/T 19789-2005 "Encasement materials Plastic film and sheet oxygen permeability test coulometer detection method" stipulates the use of coulometer to detect Plastic film and sheet oxygen permeability test method. The standard clarifies the test principle, equipment, sample prepative requirements, standardizes the operation process and data processing method, and accurately determines the oxygen permeability through coulometer. It provides a standardized means for evaluating the oxygen barrier performance of Encasement materials and helps Encasement material quality control and performance evaluation.
