Abstract

L'invention concerne un procédé de détermination du débit de fuite lors d'un essai d'étanchéité d'un objet à contrôler (2), comprenant les étapes consistant à : générer une pression négative dans l'objet à contrôler (2); envelopper une partie au moins de la surface de l'objet à contrôler (2) au moyen d'un dispositif d'enveloppement (1) de telle façon que l'espace (3) inclus entre le dispositif d'enveloppement (1) et l'objet à contrôler (2) définit un volume déterminé; remplir l'espace inclus (3) avec un gaz d'essai; détecter la fraction du gaz d'essai dans l'objet à contrôler (2); comparer la fraction du gaz d'essai dans l'espace inclus (3) à la fraction du gaz d'essai dans l'objet à contrôler (2); déterminer le débit de fuite sur la base de la comparaison de la fraction du gaz d'essai dans l'espace inclus (3) avec la fraction du gaz d'essai dans l'objet à contrôler (2).
