Abstract: In order to study the testing method of the shear modulus of the material of the insulating glass seal interval, based on the newly invented particular test device, the technical requirements of the specimen making and data processing for the shear modulus test of the material were proposed. The test verifies the test method, Three groups of shear modulus specimens of transverse and longitudinal seal interval materials were made. Considering the influence of three different thicknesses of materials, the shear modulus of seal interval material was obtained according to the shear load and displacement relationship curve. The relative difference of shear modulus of each specimen in the same group is no more than 5%. The research results show that the mechanical principle of the test device is clear, and the test results are practical and straightforward. The test process is simple, the test method is reasonable, the data processing method is simple, the test data is stable, and the shear modulus of the material of the insulating glass seal interval can be reasonably tested. According to the research conclusion, the technical suggestions for evaluating the test results are put forward.
