Find free, non-paywalled technical guidance on architectural glass marking, labeling, or glazing design practice published by the industry association, rather than relying on a paid ASTM/ANSI standard.

Steps

1. Go to glass.org's Resources > Publications > 'Glass Informational Bulletins and Technical Papers' page
2. Confirm NGA (National Glass Association) makes nearly 100 Glass Technical Papers (GTPs) available as free downloads to the general public, covering commercial/residential glass and window/door topics
3. For marking/labeling questions specifically, retrieve Glass Technical Paper FB11-06 ('Marking and Labeling of Architectural Glass'), which summarizes code identification requirements (e.g., IBC 2406.3-type etch/label rules) in plain language
4. Note that the broader GANA Glazing Manual (glazing guidelines, hazardous-location design guidance, primary/fabricated glass product info) and other downloadable manuals/design guides are now free specifically to NGA members, not the general public, per NGA's 2025 announcement
5. Use GTPs for general technical literacy and cross-check them against the actual adopted code text (IBC/IRC) for any code-compliance determination, since GTPs are industry guidance, not code
