Abstract

L'invention concerne un système d'essai (100) pour effectuer un essai d'échantillon, tel qu'un essai de mesure de la force d'étanchéité résiduelle (RSF) et/ou un essai de mesure du frottement sous compression (CF). Le système d'essai comprend une colonne (114) supportée par une structure de base (104), une cellule de charge (106) supportée par ladite colonne, une plaque d'échantillon (110a) configurée pour recevoir une pluralité d'échantillons (112), un moteur (204) et un dispositif de commande (150). La cellule de charge est configurée pour se déplacer le long de la colonne vers la structure de base et à l'opposé de celle-ci par l'intermédiaire d'une traverse (108) couplée à un actionneur (156). La pluralité d'échantillons comprend un premier échantillon et un second échantillon. Le dispositif de commande est configuré pour commander le moteur pour ajuster une position de ladite plaque d'échantillon.
