Abstract
A non-destructive method for testing sealed packages for leakage, particularly packages having a gas-permeable portion and a non-gas-permeable portion, by applying a temporary barrier over the gas-permeable portion, wherein the temporary barrier has two apertures, and enclosing the package in a testing chamber having a carrier gas flowing through it to a detector, and passing a tracer gas through the package interior via the two apertures in the temporary barrier.
