penetration firestop system in restricting the passage of fire <br /> and the transfer of heat firestop systems are required to be I fix <br /> subjected to fire testing.ASTM E814 and UL 1479 are the <br /> test methods developed specifically for the evaluation of a +Pte <br /> firestop system's ability to resist the passage of flame and <br /> hot gases, withstand thermal stresses and restrict transfer <br /> of heat through the penetrated assembly <br /> As noted, the more common route for demonstrating u. <br /> protection of penetrations for MEP members through <br /> mass timber assemblies is the use of firestop systems <br /> tested in accordance with ASTM E814 or UL 1479. Several <br /> tests have been conducted for these conditions on mass <br /> timber assemblies, which have achieved F and T ratings <br /> up to 2 hours.A summary of these tests is included in <br /> the Wood Works Inventory of Fire Resistance-Tested As noted in NDS Section 16.3,options for protecting <br /> Mass Timber Assemblies 3/Penetrations available at connections include. <br /> http://bit.ly/2FRwAPG. • Concealed connections protected by charring of wood <br /> • Fire-rated gypsum board <br /> • Other materials or methods approved by the <br /> Authority Having Jurisdiction <br /> TR 10 provides discussion on connection protection options, <br /> including unique design considerations associated with wood <br /> as a covering material for connections_ <br /> 1 <br /> yr <br /> FPInnOVaUOruc' -' <br /> Fire Protection of Connections <br /> In addition to fire-resistance rating requirements for II �+,y�^,no 1E OUP- <br /> structural wood members such as beams,columns and r� d ,�, R.cennxmn " <br /> floor/roof panels, connections between members(eg., <br /> beam-to-column connections)must have sufficient <br /> protection to provide the same fire-resistance rating <br /> Section 16.3 of the NDS states: <br /> Wood connections, including connectors, fasteners, and <br /> portions of wood members included in the connection <br /> design, shall be protected from fire exposure for the <br /> required fire-resistance time.
