Materials prescribed herein for fire resistanceshall conform to the requirements of this chapter.703.2 Fire-resistance ratings. The fire-resistance rating ofbuilding elements, components or assemblies shall be deter-mined in accordance with the test procedures set forth inASTM E119 or UL 263 or in accordance with Section 703.3.The fire-resistance rating of penetrations and fire-resistantjoint systems shall be determined in accordance Sections 714and 715, respectively. 703.2.1 Nonsymmetrical wall construction. Interiorwalls and partitions of nonsymmetrical construction shallbe tested with both faces exposed to the furnace, and theassigned fire-resistance rating shall be the shortest dura-tion obtained from the two tests conducted in compliancewith ASTM E119 or UL 263. Where evidence is furnishedto show that the wall was tested with the least fire-resistantside exposed to the furnace, subject to acceptance of thebuilding official, the wall need not be subjected to testsfrom the opposite side (see Section 705.5 for exteriorwalls).703.2.2 Combustible components.

Restrained construction shall be identi-fied on the construction documents.703.2.4 Supplemental features. Where materials, sys-tems or devices that have not been tested as part of a fire-resistance-rated assembly are incorporated into the build-ing element, component or assembly, sufficient data shallbe made available to the building official to show that therequired fire-resistance rating is not reduced.703.2.5 Exterior bearing walls. In determining the fire-resistance rating of exterior bearing walls, compliancewith the ASTM E119 or UL 263 criteria for unexposedsurface temperature rise and ignition of cotton waste dueto passage of flame or gases is required only for a periodof time corresponding to the required fire-resistance rat-ing of an exterior nonbearing wall with the same fire sepa-ration distance, and in a building of the same group.Where the fire-resistance rating determined in accordancewith this exception exceeds the fire-resistance ratingdetermined in accordance with ASTM E119 or UL 263,the fire exposure time period, water pressure and applica-tion duration criteria for the hose stream test of ASTME119 or UL 263 shall be based on the fire-resistance rat-ing determined in accordance with this section.703.3 Methods for determining fire resistance. The appli-cation of any of the methods listed in this section shall bebased on the fire exposure and acceptance criteria specified inASTM E119 or UL 263. The required fire resistance of abuilding element, component or assembly shall be permittedto be established by any of the following methods or proce-dures:1.Fire-resistance designs documented in approvedsources.2.Prescriptive designs of fire-resistance-rated buildingelements, components or assemblies as prescribed inSection 721.3.Calculations in accordance with Section 722.4.Engineering analysis based on a comparison of build-ing element, component or assemblies designs havingfire-resistance ratings as determined by the test proce-dures set forth in ASTM E119 or UL 263.5.Alternative protection methods as allowed by Section104.11.6.Fire-resistance designs certified by an approvedagency.703.4 Automatic sprinklers. Under the prescriptive fire-resistance requirements of this code, the fire-resistance ratingof a building element, component or assembly shall be estab-lished without the use of automatic sprinklers or any otherfire suppression system being incorporated as part of theassembly tested in accordance with the fire exposure, proce-dures and acceptance criteria specified in ASTM E119 or UL263. However, this section shall not prohibit or limit theduties and powers of the building official allowed by Section104.11.703.5 Noncombustibility tests.

These procedures applyto both load-bearing and nonload-bearing assemblies.722.6.2.1 Fire-resistance rating of wood frameassemblies. The fire-resistance rating of a wood frameassembly is equal to the sum of the time assigned to themembrane on the fire-exposed side, the time assignedto the framing members and the time assigned for addi-tional contribution by other protective measures such asinsulation. The membrane on the unexposed side shallnot be included in determining the fire resistance of theassembly.722.6.2.2 Time assigned to membranes. Table722.6.2(1) indicates the time assigned to membranes onthe fire-exposed side.722.6.2.3 Exterior walls. For an exterior wall with afire separation distance greater than 10 feet (3048mm), the wall is assigned a rating dependent on theinterior membrane and the framing as described inTables 722.6.2(1) and 722.6.2(2). The membrane onthe outside of the nonfire-exposed side of exterior wallswith a fire separation distance greater than 10 feet(3048 mm) shall consist of sheathing, sheathing paperand siding as described in Table 722.6.2(3).722.6.2.4 Floors and roofs. In the case of a floor orroof, the standard test provides only for testing for fireexposure from below. Except as noted in Section 703.3,Item 5, floor or roof assemblies of wood framing shallhave an upper membrane consisting of a subfloor andfinished floor conforming to Table 722.6.2(4) or anyother membrane that has a contribution to fire resis-tance of not less than 15 minutes in Table 722.6.2(1). 722.6.2.5 Additional protection. Table 722.6.2(5)indicates the time increments to be added to the fireresistance where glass fiber, rockwool, slag mineralwool or cellulose insulation is incorporated in theassembly. 722.6.2.6 Fastening. Fastening of wood frame assem-blies and the fastening of membranes to the wood fram-ing members shall be done in accordance with Chapter23.Copyright © 2020 ICC. ALL RIGHTS RESERVED.
