TESTING AND RATING
Firestop system designs are tested and listed by independent test-
ing agencies such as Underwriters Laboratories, Inc. (UL) and In-
tertek. All the key elements of each design become a part of the
listing. The fire resistance tests for through penetration firestop
systems are performed by multiple standards available globally.
However, only UL and ASTM standards come close to the Indi-
an firestop system fire resistance test methodology. The below ta-
ble describes the key characteristics of IS, ASTM, UL, EN and BS
standards while performing fire resistance test for firestop systems.

Upon passing either of the standards- IS 12458, UL1479
& ASTM E814 standard tests, through penetration firestop
systems are granted the following ratings–
