Standard Test Method for Fire Tests of Through-Penetration Fire Stops

SCOPE
1.1 This test method is applicable to through-penetration fire stops of various materials and construction. Fire stops 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 fire-stop performance during the test exposure; but such tests shall not be construed to determine suitability of the fire stop for use after test exposure.
1.3 This test method also measures the resistance of fire stops to an external force stimulated by a hose stream. However, this test method shall not be construed as determining the performance of the fire stop 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 fire stops for use where fire resistance is required.
1.5 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
1.6 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.
1.7 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.

Standard Test Method for
Fire Tests of Through-Penetration Fire Stops
This standard is issued under the fixed designation E 814; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
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 E 119 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 fire stops should be measured and specified according to
a common standard that describes the method of fire exposure and rating criteria.
