Title (EN) PENDULUM-TYPE MAR TESTING DEVICE
(FR) DISPOSITIF DE TEST DE LA RÉSISTANCE AUX DOMMAGES DE TYPE PENDULE
Abstract:
(EN) Test the mar resistance of a coating using a pendulum mar testing device that has a swing member; a pivot about which the swing member is free to move along an arc; and a stylus that has a sample-contact portion extending from the swing member that contact the coating being tested when place along the arc; wherein the swing member, pivot, stylus and any members connecting these members define a deformable linkage that permits at least the surface-contact portion of the stylus to deflect radially towards the pivot at least three millimeters when the stylus engages the test sample and wherein the dimensions and mass of the swing member and stylus are sample-contact portion of the stylus is capable of achieving a speed of at least 0.4 meters per second as it travels along the arc in an absence of a test sample.
(FR) Cette invention concerne un test de résistance aux dommages d'un revêtement faisant intervenir un dispositif de test de la résistance aux dommages de type pendule, ledit dispositif comprenant un élément oscillant ; un pivot autour duquel l'élément oscillant est libre de se déplacer sur un arc ; et un stylet ayant une partie en contact avec l'échantillon s'étendant à partir de l'élément oscillant qui entrent en contact avec le revêtement testé quand ils se trouvent sur l'arc. L'élément oscillant, le pivot le stylet et tous les organes reliant ces éléments définissent une liaison déformable qui permet au moins à la partie en contact avec la surface du stylet de dévier radialement en direction du pivot d'au moins trois millimètres quand le stylet est en contact avec l'échantillon d'essai et les dimensions et le poids desdits élément oscillant, stylet et partie en contact avec la surface du stylet permettent d'obtenir une vitesse d'au moins 0,4 mètre par seconde quand il se déplace sur l'arc en l'absence d'échantillon d'essai.
