CA 2434360

A method of testing a product for leaks includes providing a pressure system (14, 240, 340, 440) for applying to the product a reference pressure that is less than 50.6 KPa. The method also includes developing a gas flow through a leak detection sensor (9, 220, 320, 420) in response to applying the reference pressure to the product. Another step of the method includes determining, based upon the gas flow between the prodct and the pressure system, whether the product leaked an unacceptable amount during the test period.

L'invention concerne un procédé permettant de rechercher des fuites de produit comprenant un système de pression (14, 240, 340, 440) destiné à appliquer une pression de référence inférieure à 50,6 KPa sur ledit produit. Ce procédé consiste également à développer un écoulement gazeux à travers un capteur de détection (9, 220, 320, 420) de fuites en réponse à l'application de la pression de référence sur ledit produit. Ledit procédé consiste enfin à déterminer, en fonction de l'écoulement gazeux s'effectuant entre le produit et le système de pression, si la quantité de fuite de produit est inacceptable pendant la durée d'un essai.
