3 Terms and Definitions

The terms and definitions defined in GB/T 31379.2 apply to this document.

4 Principles

Artificially simulated harsh external environmental conditions were used to accelerate the aging of samples, and the size, optics, appearance, and pressure-sensitive adhesive layer of the samples before and after aging were compared.

Changes in performance.
