Test method for appearance quality of PVC coated aluminum decorative coils
The experiment was carried out in natural light away from direct sunlight. At least two samples of the same batch (total area not less than 1m2) were randomly selected and connected side by side in the same production direction, and visually inspected 3m away from the center of the assembly plate. The consistency of sample production direction should be maintained during the test.
The person who takes and places the sample shall not participate in visual inspection.
Monochrome products according to GB/T11186.2 and GB/T11186.3 color evaluation. Metallic paint and anodized film are subject to visual inspection.
