包括在铝合金上生产和测试涂层的要求，该涂层不需要经受长期暴露在风化和阳光直射下。阳极氧化工艺应用于航空航天产品的制造中，以提高耐腐蚀性，为美观目的生产彩色表面，或为识别目的对零件进行颜色编码。

Includes requirements for producing and testing a coating on aluminium alloys where the coating is not required to withstand prolonged exposure to weathering and direct sunlight. The anodizing process is applied in the manufacture of aerospace products to improve resistance to corrosion, produce coloured surfaces for aesthetic reasons or to colour code parts for identification purposes.
