Status derived from the cited listings by a published rule, never hand-assigned. Each chip
above is one evidence channel and its direction. A listing is not a permit — the authority
having jurisdiction decides.
Longboard documents its lap siding as a 6-inch extruded-aluminum system and identifies ASTM E136 noncombustibility and ASTM E84 surface-burning evaluation. CAL FIRE OSFM listing 8140-2430:0001 covers 0.06-inch-thick panels in 12- and 24-foot lengths installed horizontally over Tyvek, 1/2-inch gypsum wallboard, 7/16-inch OSB, and studs at 16 inches on centre. ICC-ES ESR-4182 separately evaluates Longboard siding as exterior veneer and unvented eave soffit.

OSFM listing 8140-2430:0001 and ICC-ES ESR-4182 have distinct assembly scopes. The BML WUI assembly names 7/16-inch OSB plus exterior gypsum; ESR-4182 requires a solid substrate and at least 5/8-inch plywood when that substrate is wood sheathing. Follow the conditions governing the proposed assembly and do not combine the least restrictive details from each document. OSFM listing is not a permit. The authority having jurisdiction decides.
