2, color fastness: this refers to the color of reflective safety clothing in a variety of environmental conditions, such as washing, drying and exposure to sunlight, can maintain its stability and do not fade.

4, friction durability: This is through the use of friction tester to simulate the wear of reflective clothing in daily use, such as friction, folding and distortion. After testing, the reflective clothing is evaluated for its reflective performance and structural integrity.

5, washing durability: This is to evaluate the durability of reflective clothing by multiple washes. Good reflective clothing should be able to withstand more than 25-50 washes without significantly reducing its reflective properties

6, ergonomics: this means that the design and material of reflective clothing should meet the requirements of ergonomics to improve the comfort and safety of the wearer. In summary, the durability evaluation criteria of reflective clothing cover many aspects such as mechanical properties, color fastness, moisture permeability, friction durability, washing durability and ergonomics. These standards ensure that reflective clothing maintains its performance and effectiveness in a variety of environments and conditions of use.
