The purpose of the pen-core circle writing tester is to assess the quality and performance of pen cores in terms of their ability to produce consistent, clear, and uninterrupted lines when writing in a circular motion. This test method simulates the writing movements commonly used in documents, such as signatures, and ensures that pen cores meet the requirements of ISO 27668-1 for documentary use. The results of the test are used to evaluate the quality and reliability of pen cores and ensure that they provide consistent writing performance.
Read MoreThe purpose of the spectacle frame endurance tester is to evaluate the mechanical endurance of spectacle frames under simulated conditions that mimic the wear and tear experienced during normal use. This test method assesses the ability of spectacle frames to withstand repeated mechanical stresses, such as bending, twisting, and flexing, without failure or deformation. The results of the test are used to determine the durability and reliability of spectacle frames and ensure that they meet the requirements of ISO 12870.

An eyeglasses frame torsion testing machine is a device used to test the torsional (twisting) properties of eyeglass frames. The machine simulates the way a person's eyes view the eyeglass frames and measures the amount of torsion present. The eyeglass frame is placed on the testing machine's platform and viewed through the machine's eyepiece. The eyepiece displays the eyeglass frame's torsional properties, and the operator can determine if the eyeglass frame meets the torsional requirements by observing the shape of the frame in the eyepiece.
