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.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
spot faults
spot faults, such as gaseous or solid impurities, attachments and fragments, cause halo together with their surrounding areas. The size of a spot fault shall be based on its core part
3.2
scratches
scratches on the glass surface caused by scratching, scraping, grinding, etc.
3.3
color spots
small color spots generated in the reflective layer
3.4
dark stripe
strip area where the brightness or reflected color of the mirror surface differs from the overall appearance
3.5
stain
cloud-like, radial, or streaky faults where the mirror surface color has changed
3.6
corrosion
localized chemical attack occurring at the edge or in the middle of the product
3.7
cluster
presence of three or more spot faults within a circle of 100mm in diameter
3.8
edge faults
faults on the edge of the finished product, including projection/concave, chip, and corners on/off
3.9
halo
phenomenon forming around a spot fault that distorts the reflected light
3.10
chip
