Function and working principle of Eyeglasses Frame Endurance Tester
Publish Time: Author: SkyLine Editor
An Eyeglasses Frame Endurance Tester is a device used to test the strength and durability of eyeglass frames. By subjecting the frames to mechanical operations such as twisting, stretching, and bending under simulated human use conditions, the tester evaluates the frames' ability to withstand these loads and assesses their quality.
Various testing methods are typically used to simulate the eyeglass frames' performance under different conditions during the fatigue testing of eyeglass frames. For example, continuous cyclic testing can be performed by repeatedly twisting and stretching the frames to simulate long-term use, while single extreme load testing can be used to simulate extreme use conditions by applying larger twisting and stretching forces.
These tests can be used to evaluate the expected lifespan of the eyeglass frames under different conditions and provide reference for manufacturers and consumers.
eyeglasses frame endurance tester Testing Methods:
Open the eyeglass legs fully and measure the distance between the two legs, d1, at the predetermined measurement point.
Fix the eyeglass frame on the instrument and set the number of test cycles (500 cycles). Start the instrument.
After the instrument rotation is complete, remove the instrument and observe the condition of the eyeglass frame.
Conditions for compliance:
a. No cracks or fractures in the eyeglass frame.
b. Deformation is no greater than 5mm.
c. The eyeglass legs can be easily opened and closed by hand and will not close due to their own weight.
