Steps
Confirm the condition is a perimeter joint — the void between the interior face of an exterior curtain-wall/spandrel assembly and the edge of the floor slab — distinct from an interior fire-resistive joint.
Select a perimeter fire barrier (PFB) system tested to ASTM E2307 using the intermediate-scale, multi-story test apparatus (ISMA), which exposes the system to fire from two stories simultaneously.
Verify the system's rating includes both the temperature-rise-based rating and the flame/hot-gas-passage rating produced by the E2307 test, and confirm both meet the project's required duration.
Check that the tested system accounts for expected deflection/deformation of the curtain wall and floor assembly under fire exposure, not just a static joint condition.
Keep the PFB system selection and documentation limited to firestop/PFB scope, routing glazing, spandrel-panel, and structural curtain-wall design questions to the curtain-wall discipline.
Known gotchas
E2307 is a full-scale/intermediate-scale system test used to establish the PFB system's rating, distinct from ASTM E2393's on-site inspection practice for already-installed joints — don't conflate testing the system with inspecting the install.
Perimeter fire containment interacts closely with curtain-wall/spandrel design (glazing, panel construction); coordinate with the curtain-wall consultant but keep the firestop scope limited to the PFB system itself, not general curtain-wall/glazing scope already covered elsewhere.
Confirm the current edition of E2307 referenced by the adopted code before citing a specific year, since the standard has been revised across multiple editions.
