Introduction

cosmetic test such as scratch/abrasion test for screen or product covers are used to ensure the product can withstand normal wears appropriately.

Test Overview

Abrasion/Scratch Test

• It's with a wear eraser that goes back and forth. This test is subjective to each company so it's hard to define a spec here. An recommendation would be performing a competitive analysis with similar product on the market.

• Here's a linear abraser test video from Taber (a company that makes the test equipment)
