Obtain the design load charts/thickness tables needed to size glass under ASTM E1300 for a wind-load calculation.

Steps

1. Search astm.org for 'E1300' — the current standard (E1300-24) is sold directly by ASTM at store.astm.org (e.g., store.astm.org/e1300-24.html) as a paid PDF/print document
2. Confirm there is no free, complete public mirror of the current E1300 charts; older superseded editions (e.g., E1300-16) circulate informally as PDFs on some third-party/fabricator sites but should not be relied on for current-code compliance since chart values and use conditions have been revised across editions
3. For non-critical, order-of-magnitude checks, note that several manufacturer technical bulletins and glass calculators (offered free by companies like Total Security Solutions or fabricators) implement E1300 methodology but are not a substitute for owning the standard when stamping engineering documents
4. Budget for direct ASTM purchase (single-standard PDF) if a licensed design professional needs the authoritative current charts
5. Confirm which E1300 edition the applicable building code or project spec incorporates by reference before purchasing, since IBC editions cite specific ASTM E1300 years
