Category 4175 is the general fire-rated covering series on this record, not WUI 8180. The covering row is class-a under ASTM E108 on attributes. OSFM 4175-2114:0101 is that covering identifier.

Warnings flag the 4175 versus 8180 series split. A covering Class A in category 4175 does not answer a WUI 8180 assembly question by itself.

Lot comparison is where that covering row meets a place. Read 4175-2114:0101 as a covering identifier in the general series, not as a substitute WUI 8180 row.

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.
The OSFM classification is assembly-specific. Match the 15/32-inch AC plywood deck, 5:12 slope, Titanium PSU30 underlayment, fasteners, exposure, and every other listing and installation condition.
