The tester is researched and produced according to the technical requirements of GB/14214-2003 "General Requirements and Test Methods for Spectacle Frames" and ISO12870:1997 "Ophthalmic Optics - Spectacle Frames - Basic Requirements and Test Methods". Clamp the eyeglass frame to both ends of the jig for a torsion test. Angular deflection and twisting by a stepper motor. After the design requires the number of twists. Stop the operation of the instrument, remove the sample, observe the degree of wear and evaluate its folding resistance, and provide reference data for material selection.
