Scope
This part of GB/T 30789 provides a pictorial reference standard for evaluating the degree of powdering of color paint coatings. This part also specifies the method for evaluating the powdering grade. When using this method, it is important to carefully distinguish between genuine aging degradation products and contaminants, especially when there is slight powdering.
