| Ablative
- Sacrifice itself with heat. Removing itself by melting or
vaporization. |
| |
| ASTM
E 119 - "Fire Tests of Building Construction
and Materials" conducted to evaluate the ability
of a fire resistive floor or wall assembly to perform its barrier
function, resisting the passage of flame, heat hot gases, and
smoke in a fire situation. |
| |
| ASTM
E 136 - "Standard Behavior of Materials
in a Vertical Tube Furnace @ 750° Celsius" |
| |
| ASTM
E 814 - "Fire Tests of Through Penetration
Fire Stops" A complementary test to ASTM E 119
and a method of subjecting through-penetration firestops to
a standard temperature-time curve, and to a subsequent application
of a hose stream. Two rating identifiers are used. They are
"T" which indicates temperature rise, and "F",
which indicates flame occurrence. |
| |
| Annular
Space
- The opening around the penetrating item. |
| |
| Area
Separation - A wall of firerated construction (expressed
in hours) which serves to divide the floor area of a building
into acceptable area limits as set forth in the code having
jurisdiction. |
| |
| Backing
Material (Safing material, Forming Material)
- Material used in firestop systems to set the depth and provide
support for the fill, void cavity material. |
| |
| Endothermic
- Characterized by or formed with absorption of heat. |
| |
| Elastomeric
- Resembling rubber. |
| |
| "F"
Rating -
A
rating usually expressed in hours indicating a specific length
of time that a fire resistive barrier can withstand fire before
being consumed or permitting the passage of flame through an
opening in the assembly. |
| |
| Fire
Barrier
- A fire resistance rated vertical or horizontal assembly of
materials designed to restrict the spread of fire in which openings
are protected. |
| |
| Fire
Damper
- A listed (approved) device, installed in ducts and air transfer
openings of an air distribution system or smoke control systems,
designed to close automatically upon detection of heat, to interrupt
migratory airflow, and to restrict the passage of flame. Fire
dampers are classified for use in either static systems that
will automatically shut down in the event of a fire, or in a
dynamic system that continues to operate during a fire. |
| |
| Fire
Rated Partition
- A partition having an assembly of materials that will afford
a given fire resistance rating (expressed in hours) to impede
the spread of fire from one area to another. |
| |
| Fire
Resistance Rating - The period of time a building
or building component maintains the ability to confine a fire
or continues to perform a structural function or both. This
is usually determined or measured by the ASTM E-119 test standard. |
| |
| Fire
Wall - A continuous (basement to roof) wall having
adequate fire resistance/rating (expressed in hours) with an
adequate structural stability under fire conditions to completely
subdivide a building or completely separate adjoining buildings
to restrict the spread of fire. |
| |
| Flame
Spread Index - A number or classification indicating
a comparative measure derived from observations made during
the process of the boundary of a zone of flame under defined
test conditions. |
| |
| Intumescence
- A characteristic of certain fire barrier products that when
exposed to heat, expand self-sealing and filling any void in
the penetration. When exposed to flame, intumescent materials
will form a hard char. |
| |
| Joint
- The linear opening in or between adjacent fire resistance
rated assemblies that is designed to allow independent movement
of the building, in any plane, caused by thermal, seismic, wind
or any other loading. |
| |
| "L"
Rating - A rating usually expressed in cubic feet
per minute per square foot of opening as determined by the air
leakage test. It is a measure of the ability of a fire resistive
assembly to resist air or smoke infiltration resulting from
pressure differences. "L" Ratings may be given for
both ambient and elevated temperatures. |
| |
| Plenum
- An enclosed portion of a building structure designed to allow
air movement, and thereby serve as part of an air distribution |
| |
| Penetrant
(Penetrating Item) - Any item passing completely
through a wall or floor, such as pipes, conduits, and cables. |
| |
| Smoke
Barrier - A continuous membrane, either vertical
or horizontal, such as a wall, floor, or ceiling assembly, that
is designed and constructed to restrict the movement of smoke.
|
| |
| Smoke
Developed Index
- A number or classification indication a comparative measure
derived from smoke obscuration data collected during the test
for surface burning characteristics. |
| |
| Surface
Flame Spread - The propagation of a flame away from
the source of ignition across the surface of the specimen. |
| |
| Splice
- The result of a factory and/or field method of joining or
connecting two or more lengths of a fire resistant joint system
into a continuous entity. |
| |
| Through-Penetration
Firestop System
- A specific field-erected construction of an assemblage of
materials designed to prevent the spread of fire through openings
which are made in floors and walls to accommodate through-penetrating
items such as electrical conduit, cable, cable trays, and metal
and plastic pipes.
|
| |
|
T-Rating
- The time period that the penetration firestop system, including
the penetrating item, limits the maximum temperature rise
to 325 degrees F above its initial temperature through the
penetration on the
non fire side, when tested in accordance with ASTM E 814.
|

| UL
- UL is the abbreviation for Underwriters Laboratories, a non-for-profit
independent testing organization for public safety. UL maintains
and operates laboratories for the examination and testing of
firestop systems. |

263 -
"Fire Tests of Building Construction and Materials"
- Similar to ASTM E 119. Evaluate the length of time that the
types of assemblies (masonry units, columns, girders, beams,
slabs etc.) will contain a fire or retain their structural integrity,
or both, dependent upon the type of assembly involved during
a predetermined test exposure. The test evaluates the assembly's
resistance to heat, and in some instances to a hose stream,
while carrying an applied load, if the assembly is load bearing. |
