3 Principles
Sample is clamped between two jaws of tension tester along clamping lines; as two clamps of tensile machine are draw apart gradually, each adhesive point in latitudinal or longitudinal direction of samples starts to be stressed successively; the stress is transmitted along the peeled off line gradually, separated and cracked until the sample is peeled off.
4 Test Equipment
4.1 Constant rate of extension type or constant rate of traverse type tension tester is adopted and the accuracy is ± 1.0% .
4.2 Clamp: the center point of two clamps of tension tester shall be on the same plumb line; the jaw line of clamp shall be vertical to plumb line and thereof clamp lines and sample shall be on the same plane. Clamp shall be able to clamp sample and make it not slide; and sample cannot be damaged obviously. The clamp width of clamp shall not be less than 30mm and the clamp face shall be flat and smooth.
