Document Type and Number:
Japanese Patent JP4288006
Kind Code:
B2
Abstract:
The invention relates to a method for the integral leak detection on test samples with relatively thin walls, in which the test sample (1) comprising the test gas is tested for leaks in a test chamber; in order to test whether or not test samples are properly filled with test gas, it is proposed that for checking the test gas concentration in the test samples (1), the test gas concentration in at least one of the test samples (1) is measured thereby that its wall (2) is provided with a leak (4), and that with this test sample (1) a leak detection process is carried out.
