Abstract

The present invention relates to a method of testing the joints for leaks in a thin plate lined storing room, in particular an underground storing room, for a fluid, a gas or a liquid. Said joints (3) are welded standing joints having at least one exterior folded fold portion (12), which is folded in such a way, that a closed duct (17) is formed in a space between said exterior folded fold portion (12) and longitudinal welding seams (13, 16), which mutually connect all the elements of said joint. A leak-testing fluid can be fed into said duct (17) thus formed, leaks being detected by sensing leak-testing fluid, which passes a welding seam (16), by means of which said folded fold portion (12) is welded. The present invention also relates to a joint adapted to the performance of the method.
