Attributes name ASTM E108 as the test standard. This record has 2 listings. OSFM 4175-1430:0101 sits beside ICC-ES ESR-2464 (ESR-2464).

Warnings place that OSFM identifier in category 4175, the general fire-rated series rather than WUI 8180. An ASTM E108 row in category 4175 is not automatically a WUI 8180 assembly identifier.

Lot comparison is how those two identifiers meet a place. The dual-listing pair is the comparable object, not a face sheet standing alone.

Specification notes

OSFM category 4175 is a general fire-rated roof covering listing, not the WUI-specific 8180 series. Confirm WUI applicability with the authority having jurisdiction.
Class A applies to the documented complete roof-panel configuration, not an isolated FRP skin. Match the Type A or Type SW-C face sheets, interior face, grid core, panel thickness, framing, supports, slope, fasteners, sealants, labeling, and installation conditions to the current report.
ESR-2464 requires the Type A and Type SW-C Class A panels to carry the UL listing mark on both interior and exterior facings. Verify the supplied labels before specification.
