GB/T 1038.2-2022 Plastics—Film and sheeting—Determination of gas-transmission rate—Part 2:Equal-pressure methods
Abstract
This document specifies two test methods for determining the gas permeability of materials such as plastic films, sheets, co-extruded materials, plastic-coated materials, and laminates under isobaric conditions — the Coulomb sensor method and gas chromatography.
This document is applicable to the determination of gas permeability in plastic films and sheets. The determination of gas permeability in other materials can be used for reference.
