Abstract

Est concerné un ensemble pour tester la résistance à l'arrachement d'un revêtement (2) fixé à un substrat (4), sur une éprouvette (6) de test. L'ensemble comporte un bâti support (8), l'éprouvette de test (6), une structure de liaison (20) fixée d'un côté à une face (18) du revêtement, et, à l'opposé, à un moyen de traction (28) pour tirer sur le revêtement (2) selon une direction (100) de biais par rapport à ladite face (18) de fixation du revêtement. En outre, sont prévus un moyen de maintien (30) fixé au bâti support (8) et présentant une surface d'appui (34) perpendiculaire à la direction de traction (100), et au moins une cale (32) présentant : - une première surface (72) plane, parallèle à la surface d'appui (34), et - une seconde surface (70) opposée à la première surface (72) et épousant la forme de ladite face (18) de fixation pour, alors que la traction opère, plaquer ladite première surface (72) contre la surface d'appui (34) du moyen de maintien (30).This concerns an assembly for testing the resistance to peeling of a coating (2) fixed to a substrate (4), on a test specimen (6). The assembly comprises a support frame (8), the test specimen (6), a connecting structure (20) fixed on one side to a face (18) of the coating, and, on the other hand, to a traction means (28) for pulling on the coating (2) in a direction (100) at an angle with respect to said coating fixing face (18). In addition, there are provided a holding means (30) fixed to the support frame (8) and having a bearing surface (34) perpendicular to the direction of traction (100), and at least one wedge (32) having: - a first flat surface (72), parallel to the bearing surface (34), and - a second surface (70) opposite the first surface (72) and matching the shape of said fixing face (18) for, then that the traction operates, press said first surface (72) against the bearing surface (34) of the retaining means (30).
