ASTM D3811 Test Fixture | GD3811-3


Model #
GD3811-3 test fixture meets ASTM D3811 requirements. ASTM D3811 measures the peak force to unwind a roll of pressure-sensitive adhesive tape. The test simulates unwind tape at low speeds. Rolls of tape are tested at a standard 1 inch sample width. The roll should be of consistent width throught the test. A free rotatation spindle test fixture holds the tape roll. The special fixture is used with one tensile grip. Unwind force is defined as the peak load during the test. Average peel force can also be measured and analyzed.
