The International Building Code (IBC) Section 714 requires every through-penetration in a fire-rated wall, floor or ceiling to be sealed with a firestop system tested in accordance with either UL 1479 or ASTM E814.

TENMAT FF360 is UL classified and tested under multiple UL Listed Systems that comply with both standards. F-ratings and T-ratings for each system are listed on the FF360 product page and through the UL Product iQ database.

Specifiers and inspectors verifying IBC compliance should match the project requirement (rating, substrate, penetrant) to a specific FF360 UL Listed System. The FF360 Specification Text Section 16055 download provides ready-to-use spec language for electrical firestopping.
