Check heat-treated glass fabrication tolerances (dimension, bow, warp) against ASTM C1048

Steps

1. Confirm the current active edition of ASTM C1048 (Standard Specification for Heat-Treated Flat Glass — covering heat-strengthened Kind HS and fully tempered Kind FT, coated and uncoated) on the ASTM store before citing a specific edition year, since multiple editions have been published over time.
2. Confirm which glass 'condition' applies to the project's spandrel or vision glass (Condition A uncoated, Condition B ceramic-coated spandrel, Condition C other coated) since dimensional and quality tolerances can vary by condition.
3. Pull the fabricator's quality control documentation showing measured bow/warp and dimensional tolerances against the current C1048 limits for the specific glass thickness and size on the project.
4. Confirm fragmentation test data (required for fully tempered glass) is on file from the fabricator, since C1048 also sets fragmentation count requirements for Kind FT glass.
5. Flag any oversized or non-standard lite dimensions for early coordination with the fabricator, since larger/thinner lites are more prone to exceeding bow/warp tolerances.
