Leak locating method for containers e.g. water and oil coolers in vehicles

摘要

The method involves immersing the test item (3) filled with a pressurised search fluid, preferably a gas, in a test tank (1) filled with test fluid (2). If any search fluid emerges at a leakage point from the test object, if the search fluid is suitably chosen, it can rise up through the test fluid. The search fluid can then show up on the surface of the test fluid indicating the presence of a leak (5). From the position of the search fluid on the surface of the test fluid the location of the leak can be determined.
