Gas permeability determination method e.g. for container walls, involves having first surface of wall to analyze gas which is directed to surface and gas passing to first surface is measured

摘要

The method involves having a first surface (7) of a wall (1) to analyze gas which is directed to the surface. The gas passing to the first surface is measured. The gas analyzed is hydrogen and introduced into an interior of a container. An independent claim is included for a device for the determination of gas permeability.
