Codes, standards, and referenced documents applicable to SFRM inspection
Where the rules come from
The SFRM inspector works down a chain of documents: the adopted building code, the referenced ASTM standards, the approved fire-resistance design (often a UL 263/ASTM E119 listing), and the manufacturer's written application instructions. IBC Chapter 17 makes sprayed fire-resistant materials a special-inspection item: Section 1705.14 requires physical and visual checks plus thickness, density, and bond/cohesion verification, and Section 1704.2.5 requires reports to the building official and the design professional.
Standards you must be able to name
- ASTM E605 - thickness and density of SFRM on structural members.
- ASTM E736 - cohesion/adhesion (bond) of SFRM.
- ASTM E119 / UL 263 - the fire test that establishes the rating; not a field test.
- ASTM E759 (deflection), E760 (impact), E761 (hose stream), E859 (air erosion), E937 (corrosion) - material-qualification tests, not routine jobsite QA.
- AWCI technical manuals, ICC-ES evaluation reports, and the manufacturer's product data.
Worked example
A drawing calls for 1½ in. of a gypsum-based SFRM on a W14×90 column under a two-hour UL design. The product data limits each pass to ½ in. The inspector sees one 1½ in. pass. Correct call: thickness may measure right, but the application does not follow the manufacturer's instructions; require three passes with set time between them, then verify with E605 and record the passes.
Traps
Do not cite E761 hose stream or E119 as field acceptance tests; do not treat an evaluation report as the application instruction; do not accept the listed design without confirming the product, density, and thickness match the listing.
