The F and T rat-ing criteria for penetration firestop systems shall be in accor-dance with ASTM E 814. See definitions of F rating and Trating. SECTION 703 fire - resistance RATINGS AND fire prescribed herein for fire resistanceshall conform to the requirements of this fire - resistance fire - resistance rating ofbuilding elements shall be determined in accordance with thetest procedures set forth in ASTM E 119 or in accordance withSection Where materials, systems or devices that havenot been tested as part of a FIRE-RESISTANCE-RATED assembly areincorporated into the assembly, sufficient data shall be madeavailable to the building official to show that the requiredfire- resistance rating is not reduced.

When the fire - resistance rating determined in accor-dance with this exception exceeds the fire - resistance ratingdetermined in accordance with ASTM E 119, the fire expo-sure time period, water pressure, and application durationcriteria for the hose stream test of ASTM E 119 shall bebased upon the fire - resistance rating determined in accor-dance with this Nonsymmetrical wall wallsand partitions of nonsymmetrical construction shall betested with both faces exposed to the furnace, and theassigned fire - resistance rating shall be the shortest durationobtained from the two tests conducted in compliance withASTM E 119.

9 When evidence is furnished to show that thewall was tested with the least fire -resistant side exposed tothe furnace, subject to acceptance of the building official,the wall need not be subjected to tests from the opposite side(see Section for exterior walls). Combustible aggre-gates are permitted in gypsum and portland cement concretemixtures approved for FIRE-RESISTANCE-RATED approved component material or admixture is permit-ted in assemblies if the resulting tested assembly meets thefire- resistance test requirements of this Restrained tested under ASTM E 119 shall not be consid-ered to be restrained unless evidence satisfactory to thebuilding official is furnished by the registered design pro-fessional showing that the construction qualifies for arestrained classification in accordance with ASTM E construction shall be identified on the Alternative methods for determining fire application of any of the alternative
