Process and system for testing the tightness of an enclosure

Description

Leak testing of a glovebox is obtained by the determination of the difference between internal pressure and a standard pressure versus time and this evolution is compared to a theoretical differential pressure corresponding to a predetermined leak for comparison of the real leak to the predetermined leak, corrections are made for outside pressure and internal temperature

Abstract (French)

Pour controler l'etancheite d'une boite a gants, on determine l'evolution temporelle de la difference entre la pression interne de l'enceinte et une pression de reference, et on compare cette evolution a celle d'une pression differentielle theorique correspondant a un taux de fuite predetermine de l'enceinte, de facon a pouvoir comparer le taux de fuite reel de l'enceinte a ce taux de fuite predetermine. Avant la comparaison, une correction de la difference de pression en fonction de la pression regnant a l'exterieur de l'enceinte et de la temperature interne a celle-ci est effectuee
