NON-DESTRUCTIVE TEST METHOD FOR TESTING THE SEALING OF AN ELECTROCHEMICAL CELL ELECTROLYTE

摘要

The invention relates to a method for testing the sealing of a part (4) comprising an electrochemical cell electrolyte, said method comprising the following steps: forming a closed cavity (18) defined by a first external surface (20) of the part containing the electrolyte to be tested; bringing a second external surface (40) of the part, opposite the first surface, into contact with a first fluid; flowing a second fluid, different from the first, through said closed cavity (18) between a cavity inlet (26) and a cavity outlet (28); and analysing fluid extracted via the outlet of the cavity (18) in order to detect the presence of the first fluid.
