CA 2104218
Condoms and similar sheaths are leak tested by being placed over a porous support form (11) referred to as a mandrel similar in shape to the condom, and applying a pressure differential between the outside and the inside of the mandrel, which is preferably hollow. With the open end of the condom sealed in an airtight manner against a smooth surface at the base (17) of the mandrel, leaks are detected by the flow of air or other gas into the mandrel interior.
On vérifie l'étanchéité des préservatifs et des protections similaires en les plaçant sur une forme de support poreux (11) appelée matrice, dont la forme est identique à celle du préservatif, puis en appliquant une différence de pression entre les parties interne et externe de la matrice qui est de préférence creuse. En positionnant de manière étanche l'extrémité ouverte du préservatif contre une surface lisse située à la base (17) de la matrice, on détecte les fuites par l'écoulement d'air ou d'un autre gaz à l'intérieur de la matrice.
