Question 1

Which ASTM standard governs the fire resistance rating test for firestop systems through-penetrations?

Accepted Answer

ASTM E814

Answer

ASTM E814 (Standard Test Method for Fire Tests of Through-Penetration Fire Stops) is the primary standard used to test and rate firestop systems.

Question 2

Under IBC, what is the minimum required F-rating for a firestop system in a 2-hour fire-rated assembly?

Accepted Answer

2 hours

Answer

The IBC requires that the F-rating of a firestop system equal or exceed the fire-resistance rating of the assembly being penetrated.

Question 3

Which organization publishes the standard UL 1479 used for firestop system testing?

Accepted Answer

Underwriters Laboratories

Answer

UL 1479 (Fire Tests of Through-Penetration Firestops) is published by Underwriters Laboratories and is equivalent to ASTM E814.

Question 4

The T-rating in a firestop system refers to the time during which:

Accepted Answer

Temperature on the unexposed side does not exceed 325°F above ambient

Answer

The T-rating measures the time a firestop system prevents the temperature on the unexposed side from rising more than 325°F (181°C) above the initial ambient temperature.

Question 5

According to IBC Section 714, which type of penetration does NOT require a firestop system in a fire-rated assembly?

Accepted Answer

Concrete column passing through a floor that is part of the column's structural system

Answer

IBC provides exceptions for structural elements such as columns that are part of a rated assembly and pass continuously through floors.
