Although the requirements for the protection of penetrations will
vary based on the type of assembly being penetrated and the type
of penetrating item, the intent of all of the provisions is essentially
the same: to restore the fire-resistance-rated assembly to its orig-
inal condition so that the penetration does not reduce the assem-
bly’s rating. Section 714 contains four main parts, which will be
discussed shortly. They include:
■ ■

Fire-resistance rated walls – Section 714.3
Fire-resistance rated horizontal assemblies – Section 714.4
Non fire-resistance rated horizontal assemblies – Section 714.5
Smoke barriers – Section 714.4.4
The fire-resistant assemblies and/or smoke-resistant walls and
horizontal assemblies are tested using the ASTM E 119 or UL 263
test in order to evaluate their ability to contain a fire, maintain their
structural ability or to do both for the period of time at which they
are rated. These two tests will also measure and evaluate heat
transfer through the building elements to help ensure the assembly
can serve its intended purpose.
Now, before we move on to the firestop application and details, it
will be easier if we acquaint ourselves with the common terminolo-
gy used in this chapter and in this book.
