ActiveTest methods for anodic oxidation coatings and organic polymer coatings on aluminium and aluminium alloys—Part 5:Assessment of resistance to cracking
铝及铝合金阳极氧化膜及有机聚合物膜检测方法 第5部分：抗破裂性的测定
Application Summary AI generated
This standard specifies test methods for evaluating the resistance to cracking of anodic oxidation coatings and organic polymer coatings on aluminium and aluminium alloys. It is applied in manufacturing and quality control settings, particularly for coated aluminium components used in construction, automotive, and aerospace industries, where coating integrity under mechanical or thermal stress is critical. The standard ensures coatings can withstand deformation without cracking during forming, installation, or service.
