* FACTORY MUTUAL FM Approval Guide® in www.approvalguide.com, or in CD For Firestop seals from Factory Mutual.
** Assembly rating,
*** FM report in preparation
FM temperature rating is based on similar fire and hose stream test as by UL, but reading is from a thermocouple placed
on the unexposed side of fire stop at 1 inch (25.4 mm) from penetration, for as long as that the temperature does not
exceed 325°F(163°C) above initial temperature, similar to T rating by UL.
FM Approval for Flammadur A77 cable coating for Group Electric Cables, listed in FM Approval (CD), May 2008, Volume 7, pg. 3.
