General Flashcards
When is a fire partition used?
- Walls separating dwelling units, such as rooms in apartments, dorms, and assisted living facilities
- Walls separating guest rooms in Group R-1 occupancies, such as hotels, as well as group R-2 and I-1 occupancies
- Walls separating tenant spaces in covered mall buildings
- Corridor Walls
- Elevator lobby separation for Group I-2 and I-3 occupancies, and for high-rise buildings and elsewhere as required by the code
What are the exceptions for fire partition use?
- Corridor walls permitted to be nonrated
- Dwelling and guest room separations in type IIB, IIIB, VB buildings equipped with automatic sprinkler systems
Walls may be 1/2 hour rated - Corridors in Group B occupancies where only a single means of egress is required
- Corridors in Group E occupancies where each classroom has at least one door that opens directly to the exterior at ground level
Openings in fire partitions must have a min of _ hour rating except for corridors, which must be protected by a _ minute fire protection assemblies
3/4 hour; 20 minute
What purposes are fire barriers used?
- Enclose vertical exit enclosures (stairways), exit passageways, horizontal exits, and incidental use areas
- separate different occupancies in mixed-occupancy situation
- separate single occupancies into different fire areas
- Provide fire barrier where required by code provisions in the IBC, as well as the other international codes
Wall or ceiling finishes between _ and _ thick must be applied directly against noncombustible backing, unless the finish is noncombustible or was tested separate from noncombustible backing
1/28” and 1/4”
What test was used exclusively for interior finishes?
ASTM E84 (IBC also allows finishes other than textiles that pass NFPA 286 and when a Class A finish would be required)
Textile wallcoverings must comply with these 3 conditions
- Class A rating according to ASTM E84
- Protected by an automatic sprinkler system
- OR they meet requirements of NFPA 286
Ceiling textile finishes must meet these requirements-
either ASTM E84 with sprinklers or NFPA 286

ASTM C1396
Standard Specification for Gypsum Board
ASTM E119
Standard Test Methods for Fire Tests of Building Construction and Materials
ATSM E119 Standard Test Methods for Fire Tests of Building Construction and Materials- what is the test?
Build a wall and light it on fire
1. heat transfer to determine temperature at surface or the temperature that adjacent materials will combust
2. Hose Stream Test- how well it withstand the impact of debris
Goal: evaluate an assembly’s ability to prevent the passage of fire, heat, and hot gases for a given amount of time
NFPA 252
Standard Methods of Fire Tests of Door Assemblies
NFPA 252, Standard Methods of Fire Tests of Door Assemblies
-evaluates ability of a door to resist flames, heat, and gas (fire-endurance)
-establishes time endurance rating for flame and durability
-hose stream test determines if the door will stay within its frame when subjected to a standard blast from a fire hose
-Similar test to UL10B and UL 10C
NFPA 257
Standard on Fire Test for Window and Glass Block Assemblies
NFPA 257, Standard on Fire Test for Window and Glass Block Assemblies
Prescribes specific fire and hose stream test procedures to establish degree of fire protection , in units of time
-determines degree of protection from spread of fire- flame, heat, and hot gas
Flammability tests for finish materials determine:
-whether a material is flammable; if it burns with applied heat or if it supports combustion
-the degree of flammability (how fast the fire spreads across material)
-how much smoke and toxic gas the material produces when ignited
