2403.1 Identification.
BC § 2403.1
Each pane shall bear the manufacturer's label designating the type and thickness of the glass or glazing material. The identification shall not be omitted unless approved and an affidavit is furnished by the glazing contractor certifying that each lite is glazed in accordance with approved construction documents that comply with the provisions of this chapter. Safety glazing shall be identified in accordance with Section 2406.3. Each pane of tempered glass shall be permanently identified by the manufacturer. The identification label shall be acid etched, sand blasted, ceramic fired, laser etched, embossed or of a type that, once applied, cannot be removed without being destroyed. Exception: Tempered spandrel glass shall be permanently labeled unless doing so would weaken, alter the performance of, or cause breakage of the spandrel glass, as determined by the manufacturer. Where the manufacturer makes such a determination, the tempered spandrel glass shall be provided with a removable paper marking by the manufacturer, and an affidavit shall be provided in accordance with this section.
