Choose between UL 972 and ASTM F1233 when specifying security/burglary-resistant glazing

Steps

1. Confirm UL 972's current status (Burglary Resisting Glazing Material) on UL's standards catalog — note it was reaffirmed without technical changes as of a recent review cycle; verify current reaffirmation/revision status before citing an edition.
2. Confirm UL 972's core acceptance criterion — impact testing (a repeated steel-ball drop test regimen, including a high-energy drop) with no penetration of the glazing as the pass criterion — against the current standard text.
3. Confirm ASTM F1233's current scope on the ASTM store — a standard test method for security glazing materials and systems evaluating resistance to a broader multi-stage attack sequence (blunt and sharp tool impacts, and in some classification levels thermal/chemical stress), producing a graded classification rather than a single pass/fail.
4. Select UL 972 when the project needs a simple burglary-resistance listing (e.g., retail storefront, ATM enclosure) and select ASTM F1233 when a graded, attack-scenario-specific classification is needed (e.g., higher-security applications with a defined threat profile).
5. Confirm which standard, if either, the local code or the owner's security consultant actually requires before specifying — these are largely voluntary/owner-driven specifications rather than baseline building code requirements.
