(Test Method)Standard Test Method for Fire Tests of Penetration Firestop Systems
Standard Test Method for Fire Tests of Penetration Firestop Systems
SIGNIFICANCE AND USE
5.1 This test method is used to determine the performance of a firestop system with respect to exposure to a standard time-temperature fire test and a hose stream test. The performance of a firestop system is dependent upon the specific assembly of materials tested including the number, type, and size of penetrations and the floors or walls in which it is installed.
5.2 Two ratings shall be established for each firestop system. An F rating shall be based upon flame occurrence on the unexposed surface, while the T rating shall be based upon the temperature rise as well as flame occurrence on the unexposed side of the firestop system. These ratings, together with detailed performance data such as the location of through-openings and temperatures of penetrating items are intended to be one factor in assessing performance of firestop systems.
SCOPE
1.1 This test method is applicable to firestop systems of various materials and construction. Firestop systems are intended for use in openings in fire-resistive walls and floors that are evaluated in accordance with Test Methods E119.
1.2 Tests conducted in conformance with this test method record firestop system performance during the test exposure; but such tests shall not be construed to determine suitability of the firestop system for use after test exposure.
1.3 This test method also measures the resistance of firestop systems to an external force stimulated by a hose stream. However, this test method shall not be construed as determining the performance of the firestop system during actual fire conditions when subjected to forces such as failure of cable support systems and falling debris.
1.4 The intent of this test method is to develop data to assist others in determining the suitability of the firestops for use where fire resistance is required.
1.5 This test method does not apply to membrane penetrations of a floor-ceiling assembly or roof-ceiling assembly that are tested as part of the assembly in accordance with Test Methods E119.
1.6 This test method does not apply to membrane penetrations of load-bearing walls.
1.7 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.8 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire-hazard or fire-risk assessment of materials, products, or assemblies under actual fire conditions.
1.9 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
1.10 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered requirements of the standard.
1.11 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

INTRODUCTION
Characteristically fire spreads from one building compartment to another by the collapse of a
barrier, or by openings through which flames or hot gases may pass, or by transfer of sufficient heat
to ignite combustibles beyond the barrier. Test Methods E119 describe the method to be used to
measure the fire-resistive performance of these barriers.
However, various techniques of providing for the distribution of services within a structure
sometimes require that openings be made in fire-resistive walls and floors to allow the passage of such
penetrating items as cables, conduits, pipes, trays, and ducts through to the adjacent compartment.
Fire-stop material is installed into these openings to resist the spread of fire.
The performance of through-penetration firestops should be measured and specified according to a
common standard that describes the method of fire exposure and rating criteria.

INTRODUCTION
Characteristically fire spreads from one building compartment to another by the collapse of a
barrier, or by openings through which flames or hot gases may pass, or by transfer of sufficient heat
to ignite combustibles beyond the barrier. Test Methods E119 describe the method to be used to
measure the fire-resistive performance of these barriers.
However, various techniques of providing for the distribution of services within a structure
sometimes require that openings be made in fire-resistive walls and floors to allow the passage of such
penetrating items as cables, conduits, pipes, trays, and ducts through to the adjacent compartment.
Fire-stop material is installed into these openings to resist the spread of fire.
The performance of through-penetration firestops should be measured and specified according to a
common standard that describes the method of fire exposure and rating criteria.
1. Scope
1.1 This test method is applicable to firestop systems of various materials and construction. Firestop systems are intended for
use in openings in fire-resistive walls and floors that are evaluated in accordance with Test Methods E119.
1.2 Tests conducted in conformance with this test method record firestop system performance during the test exposure; but such
tests shall not be construed to determine suitability of the firestop system for use after test exposure.
1.3 This test method also measures the resistance of firestop systems to an external force stimulated by a hose stream. However,
this test method shall not be construed as determining the performance of the firestop system during actual fire conditions when
subjected to forces such as failure of cable support systems and falling debris.
1.4 The intent of this test method is to develop data to assist others in determining the suitability of the firestops for use where
fire resistance is required.
1.5 This test method does not apply to membrane penetrations of a floor-ceiling assembly or roof-ceiling assembly that are
tested as part of the assembly in accordance with Test Methods E119.
1.6 This test method does not apply to membrane penetrations of load-bearing walls.
1.7 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only and are not considered standard.
1.8 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under
controlled conditions, but does not by itself incorporate all factors required for fire-hazard or fire-risk assessment of materials,
products, or assemblies under actual fire conditions.

of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory
limitations prior to use.

3.2.1.1 Discussion—
The materials and devices used to seal the opening around penetrating items are sometimes referred to as “firestops.” Note that
it is not “firestops” that are tested by this standard, but rather “firestop systems.” Due to the complex interaction during a fire
between the penetrant, the penetrated assembly, the materials and/or devices used to seal the penetration, and the specific size and
shape of the opening, it is not possible to simply test the “firestop” to develop fire resistance data.

items that penetrate the membrane on only one side of a fire-resistance rated assembly.
3.2.2.1 Discussion—
Examples of penetrating items include cables, conduits, ducts, pipes, and electrical boxes.
3.2.3 test assembly—the wall or floor that is part of the firestop system being tested into which the test specimen(s) is (are)
mounted or installed.
3.2.4 test specimen—the penetrating item or items and the materials or devices, or both, that seal the opening in the firestop
system being tested.
3.2.5 through-penetration firestop system, n—a firestop system that seals the opening around penetrating items that pass through
the entire fire-resistance rated assembly.
3.2.5.1 Discussion—
Examples of penetrating items include cables, cable trays, conduits, ducts, and pipes.
4. Summary of Test Method
4.1 This method of testing through-penetration firestop systems exposes firestop systems to a standard temperature-time fire,
and to a subsequent application of a hose stream.
4.2 Ratings are established on the basis of the period of resistance to the fire exposure, prior to the first development of through
openings, flaming on the unexposed surface, limiting thermal transmission criterion, and acceptable performance under application
of a hose stream.
E814 − 13a (2017)
5. Significance and Use
5.1 This test method is used to determine the performance of a firestop system with respect to exposure to a standard
time-temperature fire test and a hose stream test. The performance of a firestop system is dependent upon the specific assembly
of materials tested including the number, type, and size of penetrations and the floors or walls in which it is installed.
5.2 Two ratings shall be established for each firestop system. An F rating shall be based upon flame occurrence on the
unexposed surface, while the T rating shall be based upon the temperature rise as well as flame occurrence on the unexposed side
of the firestop system. These ratings, together with detailed performance data such as the location of through-openings and
temperatures of penetrating items are intended to be one factor in assessing performance of firestop systems.
6. Control of Fire Tests
6.1 Time-Temperature Curve—The fire environment within the furnace shall be in accordance with the standard time-
temperature curve shown in Fig. 1. The points on the curve that determine its character are:
Ambient at 0 min
1000°F (538°C) at 5 min
1300°F (704°C) at 10 min
1550°F (843°C) at 30 min
1700°F (927°C) at 60 min
1850°F (1010°C) at 120 min
2000°F (1093°C) at 240 min
2300°F (1260°C) at 480 min or over
6.2 Furnace Temperatures:
6.2.1 The temperature fixed by the curve shall be the average temperature obtained from the readings of thermocouples
symmetrically disposed and distributed within the test furnace to show the temperature near all parts of the assembly. Use a
2 2
minimum of three thermocouples, with not fewer than five thermocouples per 100 ft (9.29 m ) of floor surface, and not fewer than
nine thermocouples per 100 ft of wall specimen surface.
6.2.2 Enclose the thermocouples in sealed protection tubes of such materials and dimensions that the time constant of the
protected thermocouple assembly lies within the range (see Note 1) from 300 to 400 s. The exposed length of the pyrometer tube
and thermocouple in the furnace chamber shall be not less than 12 in. (300 mm). Use of other types of protection tubes or
pyrometers shall be acceptable provided that temperature measurements obtained in accordance with Fig. 1 are within the limit
of accuracy that applies for furnace temperature measurements.
NOTE 1—A typical thermocouple meeting these time-constant requirements may be fabricated by fusion-welding the twisted ends of No. 18 B and S
gage (0.040 in.) (1.02 mm) Chromel-Alumel wires, mounting the leads in porcelain insulators and inserting the assembly so the thermocouple bead is
0.50 in. (13 mm) from the sealed end of a standard weight, nominal ⁄2-in. iron, steel, or Inconel pipe. (Inconel is a trademark of Inco Alloys, Inc., 3800
Riverside Dr., P.O. Box 1958, Huntington, WV 25720.) The time constant for this and for several other thermocouple assemblies was measured in 1976.
The time constant may also be calculated from knowledge of its physical and thermal properties. See Research Report RR:E05-1001, available from
ASTM Headquarters.
6.2.3 For floors, place the junction of the thermocouples 12 in. (300 mm) away from the exposed face of the assembly. In the
case of walls, place the thermocouples 6.0 in. (150 mm) away from the exposed face.
NOTE 1—For a closer definition of the temperature-time curve, see Annex A1.
FIG. 1 Temperature-Time Curve
E814 − 13a (2017)
6.2.4 Read the temperature at intervals not exceeding 5 min during the first 120 min. Thereafter, the intervals shall not exceed
10 min.
6.2.5 The accuracy of the furnace control shall be such that the area under the temperature-time curve, obtained by averaging
the results from the pyrometer or thermoelectric device readings, is within 10 % of the corresponding area under the standard
temperature-time curve shown in Fig. 1 for fire tests of 60 min or less duration; within 7.5 % for those over 60 min and not more
than 120 min; and within 5 % for tests exceeding 120 min in duration.
6.3 Unexposed Surface Temperatures:
6.3.1 Measure temperatures on the surface of the materials, devices, or both, that are used to seal the opening in the test
assembly.
6.3.2 Measure the temperature of the test assembly.
6.3.3 Measure temperature at each of the locations on the unexposed surface of the penetrating item and floor or wall assembly
as shown in Fig. 2.
6.3.4 For tests of membrane penetration firestop systems, in addition to the requirements of 6.3.3, measure temperature at each
of the locations on the non-fire side of the test assembly as shown in Fig. 3 for test assemblies that include membrane penetrations
on only one face of the test assembly, or as shown in Fig. 4 for test assemblies that include conditions representative of both sides
of the membrane penetration on one surface of the wall.
6.3.4.1 Discussion—The area in which thermocouples “G” are located, as shown in Fig. 3 and Fig. 4, is the perpendicular
projections of the test assemlby opening area on the non-fire side of the un-penetrated membrane.
6.3.5 Additional temperature measurements shall be made at the discretion of the testing agency to obtain representative
information on the performance of the firestop systems.
6.3.6 For the purpose of obtaining supplementary information during tests of membrane penetrations, the temperature inside of
each wall cavity having a membrane penetration shall be measured using one or more thermocouples. Such thermocouples shall
be located 3 6 0.25 in. (76 6 6 mm) vertically from the inside top of the wall cavity, and each located 3 6 0.25 in. (76 6 6 mm)
in. horizontally from the penetration centerline. Wires for the thermocouples shall be routed so as not to impact the fire
performance measurements that are made on the non-fire side membrane.
6.3.7 Temperature measurements shall be made with thermocouples placed under flexible pads specified in Annex A2. The pads
shall be held firmly against the surface and shall fit closely about the thermocouples. The thermocouple junction shall be located
Legend:
A—At a point on the surface of the materials or devices, or both, that seal the opening 1 in. (25 mm) from one through-penetrating item for each type of penetrating item
employed in the field of the materials or devices, or both, that seal the opening. If the grouping of penetrating items through the test sample prohibits placement of the
thermocouple pad, the thermocouple shall not be required.
B—At a point at the periphery on the surface of the materials or devices, or both, that seal the opening.
C—At a minimum of three points on the surface of the materials that seal the opening, approximately equidistant from a penetrating item or group of penetrating items
in the field of the materials that seal the opening and the periphery.
D—At one point on any frame that is installed about the perimeter of the opening.
E—At one point on the
