Abstract
This part of GB/T 30789 provides a method for assessing the peeling grade by comparing with the standard illustrations and using the definitions specified in ISO 46281. ISO 46281 defines a system for assessing the number and size of defects caused by coating aging, as well as the degree of uniformity in appearance, and outlines the general principles of the assessment system. This evaluation system is applicable to defects caused by aging and weathering, as well as uniform changes such as color changes (e.g., yellowing).
