Tape Pull Test

The commonly used instrument is a tensile tester, which is mainly to slowly apply a load to both ends of the sample, so that the working part of the sample is partially subjected to axial tension, causing the sample to elongate in the axial direction. It is generally carried out until it is pulled off. The tensile strength and plastic properties of the material can be determined through the tensile test. Tensile test specimens should meet the relevant national and industrial standards for tensile testing of different materials.
