1、Designation: E814 13a (Reapproved 2017) An American National StandardStandard Test Method forFire Tests of Penetration Firestop Systems1This standard is issued under the fixed designation E814; the number immediately following the designation indicates the year oforiginal adoption or, in the case of

2、 revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.INTRODUCTIONCharacter

3、istically fire spreads from one building compartment to another by the collapse of abarrier, or by openings through which flames or hot gases may pass, or by transfer of sufficient heatto ignite combustibles beyond the barrier. Test Methods E119 describe the method to be used tomeasure the fire-resi

4、stive performance of these barriers.However, various techniques of providing for the distribution of services within a structuresometimes require that openings be made in fire-resistive walls and floors to allow the passage of suchpenetrating items as cables, conduits, pipes, trays, and ducts throug

5、h 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 acommon standard that describes the method of fire exposure and rating criteria.1. Scope1.1 Th

Firestop systems are in-tended for use in openings in fire-resistive walls and floors thatare evaluated in accordance with Test Methods E119.1.2 Tests conducted in conformance with this test methodrecord firestop

The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.8 This standard is used to measure and describe therespons

Terminology3.1 Definitions:3.1.1 For definitions of terms used in this test method referto Terminology E176.3.2 Definitions of Terms Specific to This Standard:3.2.1 firestop system, na specific combination of penetrat-ing item or items, the specific construction that is penetrated,and the materi

19、als or devices, or both, that seal the openingprovided to accommodate one or more items that penetrate intoor through a fire-resistance rated assembly.3.2.1.1 DiscussionThe materials and devices used to sealthe opening around penetrating items are sometimes referred toas “firestops.” Note that it is

20、 not “firestops” that are tested bythis standard, but rather “firestop systems.” Due to the complexinteraction during a fire between the penetrant, the penetratedassembly, the materials and/or devices used to seal thepenetration, and the specific size and shape of the opening, it isnot possible to s

21、imply test the “firestop” to develop fireresistance data.3.2.2 membrane-penetration firestop system, na firestopsystem that seals the opening provided to accommodate one ormore items that penetrate the membrane on only one side of afire-resistance rated assembly.3.2.2.1 DiscussionExamples of penetra

24、trays, conduits, ducts, and pipes.4. Summary of Test Method4.1 This method of testing through-penetration firestopsystems 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 ofresistance

25、 to the fire exposure, prior to the first development ofthrough openings, flaming on the unexposed surface, limitingthermal transmission criterion, and acceptable performanceunder application of a hose stream.5. Significance and Use5.1 This test method is used to determine the performanceof a firest

26、op system with respect to exposure to a standardtime-temperature fire test and a hose stream test. The perfor-mance of a firestop system is dependent upon the specificassembly of materials tested including the number, type, andsize of penetrations and the floors or walls in which it isinstalled.5.2

27、Two ratings shall be established for each firestop sys-tem. An F rating shall be based upon flame occurrence on theunexposed surface, while the T rating shall be based upon thetemperature rise as well as flame occurrence on the unexposedside of the firestop system. These ratings, together withdetail

28、ed performance data such as the location of through-openings and temperatures of penetrating items are intended tobe one factor in assessing performance of firestop systems.6. Control of Fire Tests6.1 Time-Temperature CurveThe fire environment withinthe furnace shall be in accordance with the standa

29、rd time-temperature curve shown in Fig. 1. The points on the curve thatdetermine its character are:Ambient at 0 min1000F (538C) at 5 min1300F (704C) at 10 min1550F (843C) at 30 min1700F (927C) at 60 min1850F (1010C) at 120 min2000F (1093C) at 240 min2300F (1260C) at 480 min or over6.2 Furnace Temper

33、of theprotected thermocouple assembly lies within the range (seeNote 1) from 300 to 400 s. The exposed length of thepyrometer tube and thermocouple in the furnace chamber shallbe not less than 12 in. (300 mm). Use of other types ofprotection tubes or pyrometers shall be acceptable providedthat tempe

34、rature measurements obtained in accordance withFig. 1 are within the limit of accuracy that applies for furnacetemperature measurements.NOTE 1A typical thermocouple meeting these time-constant require-ments may be fabricated by fusion-welding the twisted ends of No. 18 Band S gage (0.040 in.) (1.02

The time constant may also be calculated fromknowledge of its physical and thermal properties. See Research ReportRR:E05-1001, available from ASTM Headquarters.6.2.3 For floors,
