Abstract

Methods for testing leakage in a tank system are disclosed including sealing the tank system, creating a pressure variation in the sealed tank system, measuring the pressure values in the sealed tank system at predetermined time intervals for a measuring period, and comparing the shape of a curve formed by the measured pressure values to a predetermined curve for the system, whereby if that comparison exceeds a predetermined limit value, the leakage test is disregarded. Apparatus for carrying out such testing is also disclosed.
