Active Standard ASTM C1422 / C1422M | Developed by Subcommittee: C14.08

Historical (view previous versions of standard)
1.1 This specification covers the requirements for chemically strengthened glass products that originate from flat glass and are used in general building construction, transportation, and other specialty applications, such as copy machine scanners, computer disks, and flat glass screens for television monitors. Techniques such as ion implantation, dealkalization, etch-strengthening, and glaze coatings are specifically excluded.
1.2 Classification of chemically strengthened glass products is based on the laboratory measurements of surface compression and case depth and not on the modulus of rupture (MOR). This specification does not purport to address end-use performance.
1.3 A test method for the measurement of case depth and surface compression is included in Section 8.
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
