1.1 This specification covers the requirements for chemically strengthened glass products that are used in general building construction, transportation, solar, and other electronic applications, such as PC screens, notebooks, tablets, smart phones, and E-readers, as well as copy machine scanners, computer disks, and flat glass screens for television monitors. The technique covered in this specification usually involves conducting ion exchange of constituent alkali ions in a glass product by immersing it in a bath of molten salt containing larger alkali ions. Penetration of the larger ions into smaller host sites produces a layer of compression on the surface which strengthens the glass. Techniques such as ion implantation, dealkalization, etch-strengthening, and glaze coatings are specifically excluded from this specification.
