Automotive Lighting Mechanical Wear Test Chamber

2. Product Introduction

Automotive Lighting Mechanical Wear Test Chamber Suitable for testing the mechanical wear resistance of the exterior or components of automotive lighting devices. Main simulation test mixture: spray pressure, spray flow rate, spray spacing, and spray time are used to test the sample. After the testBy measuring the average changes in transmittance and diffuse transmittance of the sample, the degree of mechanical wear damage to the sample can be determined.
