Aluminum coated glassmirror 1 Scope This standard specifies the terms and definitions, classification, requirements, test methods, inspection rules, as well as marking, packaging, transportation and storage of aluminum coated glassmirror. This standard is applicable to the mirrors intended for indoor use, which are manufactured using flat glass as the substrate, coated with an aluminum film through vacuum magnetron sputtering coating or vacuum evaporation coating processes, and subsequently provided with a protective layer of paint. This standard is not applicable to aluminum coated glassmirrors made with non-flat glass or processed flat glass products as the substrate, such as mirrors made from patterned glass, tempered glass, semi-tempered glass, laminated glass, or hot-bent glass. 2 Normative references The following referenced documents are indispensable for the application of this document.
