The GB 8808-1988 standard specifies the method for determining the disbonding force of soft composite plastic materials, which is suitable for the disbonding force test of various plastics compounded on substrates. The test is carried out by T-type disbonding test to determine the average disbonding force between the composite layer and the substrate. The sample size varies depending on the material used. The test environment should be carried out at 23 +/- 2 ° C and 45% -55% relative humidity. The test shall be carried out using a Tensile Testing Machine with a graphic recording device and at a specified speed. The test results are determined by the disbonding force Linear dispersion shape and take the arithmetic average value. The report shall include detailed sample information and test data.
