ActiveTesting of cores - Part 7: Determination of flexural modulus by the three-point method
纸芯的测定 第7部分：弹性模量的测定（三点法）
Application Summary AI generated
This standard specifies the three-point bending test method for determining the flexural modulus of paper cores, which are cylindrical tubes used as winding supports in the paper, film, and textile industries. It is applied in quality control and material specification contexts to evaluate the stiffness and structural integrity of cores under load, ensuring they can withstand winding tensions without excessive deformation. The test is critical for manufacturers and users of cores in converting processes, such as paper mills and packaging production lines.
