T-peel test fixture for a vertical test machine. The test fixture includes an upper grip (12) for holding an arm of a peel specimen that has a hangover tail and a lower grip (14) for holding the other arm of the peel specimen. A first rack (18)is connected to a support hanger (38). The upper grip and the first rack move in a vertical direction at a selected speed. A second rack including a support plate (24)located to support the specimen hangover tail is driven in the vertical direction at one-half the selected speed. The fixture thus supports the hangover tail so that symmetry is maintained with respect to gravity to suppress the interfering effect of gravity on a peel test.
