Abstract
The invention relates to a method for determining the permeation of a barrier layer on the surface of a container (), wherein the container is placed inside a pressure-tight closeable vessel (), is degasified after a conditioning period on the side comprising the barrier layer, the pressure is measured for the duration thereof and measuring data therefrom enables the permeation of the barrier layer to be determined. The permeation of a plurality of containers () can be determined for an industrial application in a consecutive manner in a relatively short period of time by using very simple measuring devices. The invention is characterized in that the pressure-tight closeable vessel () and the container () arranged therein are evacuated, the partial pressures of several substances emitted from the wall of the container are measured and the increase in the pressure-time-curve is determined, representing a direct measurement of the quality of the barrier layer.
