CODES AND STANDARDS
The code text in NBC 2016, section 3.4.5 & 3.4.5.4 requires through
penetrations to be protected by fire stop systems having the same
fire-resistance rating as that of the floor/wall. To establish the fire-re-
sistance rating of the firestop system, the National Building code of
India recommends using accepted standards. In India, IS 12458
standard is available for use in case of the firestop fire-resistance
test. IS 12458 standard in India, is similar in requirement and test
methodology as ASTM E814 and UL 1479 standards.
In the US Building code IBC 2015, the code text in Section 714.3.1
requires through penetrations to be protected in accordance with
Section 714.3.1.1 (as part of the fire-resistance-rated assembly) or
Section 714.3.1.2 (by a through- penetration firestop system, tested
and listed per the ASTM E 814 or UL 1479 standard). However,
Section 714.3.1 includes an exception that allows two methods for
protecting penetrations in lieu of a system tested in accordance
with ASTM E 119 or UL 263 (see Section 714.3.1.1), or ASTM E
814 or UL 1479 (see Section 714.3.1.2). This exception is limited
to steel, ferrous or copper pipes, tubes or conduits and focuses
on the protection of the annular space. Also, the exception is limit-
ed to the non-combustible pipes, tubes or conduits mentioned and
would exclude any type of combustible penetrants such as cables,
insulated wiring, plastic pipes or items such as ducts, chimneys or
combustion appliance vents.
