To an imaginary line between two buildings on the distance shall be measured at right angles from the faceof the fire-resistance-rated wall having protectedopenings, which restricts the spread of fire and extends contin-uously from the foundation to or through the roof, with suffi-cient structural stability under fire conditions to allow collapseof construction on either side without collapse of the WINDOW window constructed andglazed to give PROTECTION against the passage of materials or materials approvedfor use as fireblocking, installed to resist the free passage offlame to other areas of the building through concealed FIRE DOOR combination of afiredoor, a frame, hardware and other accessories installed in a hor-izontal plane, which together provide a specific degree of fireprotection to a through-opening in a fire-resistance-rated floor(see Section ).

SECTION 703 FIRE-RESISTANCE RATINGS AND FIRE prescribed herein forfire resistanceshall conform to the requirements of this Fire-resistance ratingofbuilding elements, components or assemblies shall be deter-mined in accordance with the test procedures set forth inASTM E 119 or UL 263 or in accordance with Section materials, systems or devices that have not been testedas part of a fire-resistance-rated assembly are incorporated intothe building element, component or assembly, sufficient datashall be made available to thebuilding officialto show that therequiredfire-resistance ratingis not reduced. Materials andmethodsofconstructionused to protect joints and penetrationsin fire-resistance-rated building elements, components orassemblies shall not reduce the requiredfire-resistance :In determining thefire-resistance ratingofexterior bearing walls, compliance with the ASTM E 119 orUL 263 criteria for unexposed surface temperature rise andignition of cotton waste due to passage of flame or gases isrequired only for a period of time corresponding to therequiredfire-resistance ratingof an exterior nonbearingwall with the samefire separation distance, and in a build-ing of the same group.

8 When thefire-resistance ratingdetermined in accordance with this exception exceeds thefire-resistance ratingdetermined in accordance with ASTME 119 or UL 263, the fire exposure time period, water pres-sure and application duration criteria for the hose stream testof ASTM E 119 or UL 263 shall be based upon thefire-resistance ratingdetermined in accordance with Nonsymmetrical wall wallsand partitions of nonsymmetrical construction shall betested with both faces exposed to the furnace, and theassignedfire-resistance ratingshall be the shortest durationobtained from the two tests conducted in compliance withASTM E 119 or UL 263. When evidence is furnished toshow that the wall was tested with the least fire-resistant sideexposed to the furnace, subject to acceptance of thebuildingofficial, the wall need not be subjected to tests from theopposite side (see Section forexterior walls).

Any compo-nent material or admixture is permitted in assemblies if theresulting tested assembly meets the fire-resistance testrequirements of this Restrained tested under ASTM E 119 or UL 263 shall not beconsidered to be restrained unless evidence satisfactory tothebuilding officialis furnished by theregistered designprofessionalshowing that the construction qualifies for FLORIDA BUILDING CODE BUILDINGFIRE AND SMOKE PROTECTION FEATURES restrained classification in accordance with ASTM E 119 orUL 263. Restrained construction shall be identified on Alternative methods for determining fire application of any of the alternative methods listed in thissection shall be based on the fire exposure and acceptance crite-ria specified in ASTM E 119 or UL 263.

Fire-resistance designs documented in Prescriptive designs of fire-resistance-rated buildingelements, components or assemblies as prescribed inSection Calculations in accordance with Section Engineering analysis based on a comparison of buildingelement, component or assemblies designs havingfire-resistance ratingsas determined by the test proce-dures set forth in ASTM E 119 or UL Alternative PROTECTION methods as allowed by Noncombustibility tests indicated in and shall serve as criteria for acceptance ofbuilding materials as set forth in Sections , in Type I, II, III and IV construction.
