ISO 36 determines the strength required to separate two plies of fabric bonded together with rubber, or a rubber and a fabric ply bonded together. This test is referred to as a “T-peel” test, because as the two adherends are pulled apart, they form the shape of a “T”. Specimens for ISO 36 are 25 mm wide and are pulled apart at 50 mm/min for a minimum separation of 100 mm. Common results are the average, minimum and maximum peel force and peel strength values. The challenges of testing to this standard are: Data rate used to capture peaks and troughs Gripping materials of varying thickness Eliminating slippage throughout the test
