INTRODUCTION 1

"The performance of walls, columns, floors, and other building members under fireexposure conditions is an item of major importance in securing constructions thatare safe, and that are not a menace to neighboring structures nor to the public.Recognition of this is registered in the codes of many authorities, municipal andother. It is important to secure balance of the many units in a single building, andof buildings of like character and use in a community; and also to promoteuniformity in requirements of various authorities throughout the country. To dothis it is necessary that the fire-resistive properties of materials and assemblies bemeasured and specified according to a common standard expressed in terms thatare applicable alike to a wide variety of materials, situations, and conditions ofexposure.

Such a standard is found in the methods that follow. They prescribe a standardexposing fire of controlled extent and severity. Performance is defined as the periodof resistance to standard exposure elapsing before the first critical point in behavioris observed. Results are reported in units in which field exposures can be judgedand expressed.

The methods may be cited as the "Standard Fire Tests," and the performance orexposure shall be expressed as "2-h," "6-h," "1/2-h," etc.

When a factor of safety exceeding that inherent in the test conditions is desired, aproportional increase should be made in the specified time-classification period."

The ASTM E119 test procedure is identical or very similar to the following standardtest methods:

UL 263UBC 7-1

NFPA 251ANSI A2.1

"1. Scope1.1 The test methods described in this fire-test-response standard are applicableto assemblies of masonry units and to composite assemblies of structural materialsfor buildings, including bearing and other walls and partitions, columns, girders,beams, slabs, and composite slab and beam assemblies for floors and roofs. Theyare also applicable to other assemblies and structural units that constitute

permanent integral parts of a finished building.1.2 It is the intent that classifications shall register performance during theperiod of exposure and shall not be construed as having determined suitability foruse after fire exposure.1.3 This standard should be used to measure and describe the properties ofmaterials, products, or assemblies in response to heat and flame under controlledlaboratory conditions and should not be used to describe or appraise the fire hazardor fire risk of materials, products, or assemblies under actual fire conditions.However, results of this test may be used as elements of a fire risk assessment whichtakes into account all of the factors which are pertinent to an assessment of the firehazard of a particular end use.

Note 1 - A method of fire hazard classification based on rate of flame spread iscovered in ASTM Method E84, Test for Surface Burning Characteristics ofBuilding Materials.

1.4 The results of these tests are one factor in assessing fire performance ofbuilding construction and assemblies. These methods prescribe a standard fireexposure for comparing the performance of building construction assemblies.Application of these test results to predict the performance of actual buildingconstruction requires careful evaluation of test conditions.

1.5 The values stated in inch-pound units are to be regarded as the standard.The values given in parentheses are for information only.

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 toestablish appropriate safety and health practices and determine the applicability ofregulatory limitation prior to use."

"4. Significance and Use4.1 This test method is intended to evaluate the duration for which the types ofassemblies noted in 1.1 will contain a fire, or retain their structural integrity orexhibit both properties dependent upon the type of assembly involved during apredetermined test exposure.4.2 The test exposes a specimen to a standard fire exposure controlled to achievespecified temperatures throughout a specified time period. In some instances, thefire exposure may be followed by the application of a specified standard fire hosestream. The exposure, however, may not be representative of all fire conditionswhich may vary with changes in the amount, nature and distribution of fireloading, ventilation, compartment size and configuration, and heat sinkcharacteristics of the compartment. It does, however, provide a relative measure offire performance of comparable assemblies under these specified fire exposure

conditions. Any variation from the construction or conditions (that is, size, methodof assembly, and materials) that are tested may substantially change theperformance characteristics of the assembly.4.3 The test standard provides for the following:4.3.1 In walls, partitions and floor or roof assemblies:4.3.1.1 Measurement of the transmission of heat.4.3.1.2 Measurement of the transmission of hot gases through the assembly,sufficient to ignite cotton waste.4.3.1.3 For load bearing elements, measurement of the load carrying ability ofthe test specimen during the test exposure.

4.3.2 For individual load bearing assemblies such as beams and columns:Measurement of the load carrying ability under the test exposure with someconsideration for the end support conditions (that is, restrained or not restrained).

4.4 The test standard does not provide the following:4.4.1 Full information as to performance of assemblies constructed withcomponents or lengths other than those tested.4.4.2 Evaluation of the degree by which the assembly contributes to the firehazard by generation of smoke, toxic gases, or other products of combustion.4.4.3 Measurement of the degree of control or limitation of the passage of smokeor products of combustion through the assembly.4.4.4 Simulation of the fire behavior of joints between building elements such asfloor-wall or wall-wall, etc., connections.4.4.5 Measurement of flame spread over surface of tested element.4.4.6 The effect of fire endurance of conventional openings in the assembly, thatis electrical receptacle outlets, plumbing pipe, etc., unless specifically provided forin the construction tested."

TEST PROCEDUREVertical Test Furnace

The test furnace is designed to allow the specimen to be uniformly exposed to thespecified time-temperature conditions. It is fitted with 39 symmetrically-locatedpropane gas burners designed to allow an even heat flux distribution across the faceof a test specimen. Furnace pressures may be maintained at any value from +0.04"W.C. to -0.20" W.C. It must be realized that any full-size vertical fire test furnacewill have a pressure difference between the bottom and top of approximately 0.10in. W.C. after operating temperatures are reached. For this reason, the furnace is


LA

BO R AT ORIE

S

OM

EGA POINT

operated by controlling the pressure within the furnace (with respect to thelaboratory ambient pressure) by regulating the pressure at a specific horizontalplane in the furnace. Many times the furnace pressure will be adjusted so that the"neutral pressure plane" (that where the pressure difference between the furnaceinterior and the laboratory is zero) is at a desired location: for instance; at the top,at a point 1/3 of the way down from the top, or at the bottom of the specimen.

The temperature within the furnace is determined to be the mathematical averageof thermocouples located symmetrically within the furnace and positioned twelveinches away from the exposed face of the test specimen. The materials used in theconstruction of these thermocouples are those suggested in the test standard.During the performance of a fire exposure test, the furnace temperatures aremonitored at least every 15 seconds and displayed for the furnace operator to allowcontrol along the specified temperature curve. A paper printout of the data isproduced every 30 seconds, and all data is saved to hard disk at intervals of onceper minute unless more often is requested.

The fire exposure is controlled to conform with the standard time-temperaturecurve shown in Figure 1, as determined by the table below:

than 2 hours and 5% for those tests of 2 hours or more duration.

Temperatures of Unexposed Surfaces

Temperatures of unexposed surfaces are monitored using 24 gauge, Type Kthermocouples placed under 6 in. x 6 in. x 0.4 in. thick dry, felted pads as describedin the standard. Temperature readings are taken at not less than nine points onthe surface, at intervals not exceeding 1.0 minute. The temperature on theunexposed surface of a test specimen during the test is taken to be the averagevalue of all thermocouples.

Applied Load

If required, this test method may be used to expose a horizontal or vertical assemblyto fire while maintaining a live load on test specimen. This is accomplished byapplying a uniform load hydraulically, with actuators designed for that purpose.

Fire Endurance Test

The fire exposure is continued on the specimen with its applied load if applicable,until failure occurs, or until the specimen has withstood the test conditions for thedesired fire endurance rating.

Hose Stream Test

"11.1 Where required by the conditions of acceptance, subject a duplicate specimento a fire exposure test for a period equal to one half of that indicated as theresistance period in the fire endurance test, but not for more than 1 h, immediatelyafter which subject the specimen to the impact, erosion, and cooling effects of a hosestream directed first at the middle and then at all parts of the exposed face, changesin direction being made slowly.

11.2 Exemption - The hose stream test shall not be required in the case ofconstructions having a resistance period, indicated in the fire endurance test, of lessthan 1 h.

11.3 Optional Program - The submitter may elect, with the advice and consent ofthe testing body, to have the hose stream test made on the specimen subjected tothe fire endurance test and immediately following the expiration of the fireendurance test.

11.4 Stream Equipment and Details - The stream shall be delivered through a21/2-in. (64-mm) hose discharging through a National Standard Playpipe ofcorresponding size equipped with a 11/8-in. (28.5-mm) discharge tip of the standard-

11.5 Nozzle Distance - The nozzle orifice shall be 20 ft (6-m) from the center of theexposed surface of the test specimen if the nozzle is so located that when directed atthe center its axis is normal to the surface of the test specimen. If otherwiselocated, its distance from the center shall be less than 20 ft by an amount equal to 1ft (305-mm) for each 10 deg of deviation from the normal."

Correction Factor

When the indicated resistance period is 1/2 h or over, determined by the failurecriteria of the standard, a correction shall be applied for variation of the furnaceexposure from that prescribed, where it will affect the classification. This is to bedone by multiplying the indicated period by two thirds of the difference in areabetween the curve of average furnace temperature and the standard curve for thefirst three fourths of the period and dividing the product by the area between thestandard curve and a base line of 68°F (20°C) for the same part of the indicatedperiod, the latter area increased by 3240°F•min to compensate for the thermal lagof the furnace thermocouples during the first part of the test. For a fire exposure inthe test higher than standard, the indicated resistance period shall be increased bythe amount of the correction. For a fire exposure in the test lower than standard,the indicated resistance period shall be similarly decreased for fire exposure belowstandard. The correction is accomplished by mathematically adding the correctionfactor, C, to the indicated resistance period.

EGA POINT

The correction can be expressed by the following equation:

C =2 I (A – As)3 (As + L)

where:

C = correction in the same units as I,I = indicated fire-resistance period,

A = area under the curve of indicated average furnace temperature for thefirst three fourths of the indicated period,

As = area under the standard furnace curve for the same part of theindicated period, and

L = lag correction in the same units as A and As (54°F•h or 30°C•h(3240°F•min or 1800°C•min))

TEST SPECIMEN CONSTRUCTION

Pre-manufactured steel faced, polystyrene foam filled sandwich panels weredelivered to the laboratory by the client, bearing the inspection mark of PFSCorporation (NERQA-251). The manufacturer supplied the following information:

Steel Skins: 26 GA. (0.019 min ± 0.0030 inches) hot dip galvanized. SD50 G90,with a minimum yield stress of 50 ksi.

EPS Foam: 1.0 pcf nominal density, furnished by Carpenter (NER-QA 204).

Adhesive: Mor-Ad M-640 & 642, manufactured by Morton Chemical, classifiedas Type II, Class 2.

The panels were three feet wide, ten feet long and nominally four inches thick. Theedges were designed to snap into each other (see drawing, Appendix A) and lock intoplace. The test wall was constructed by snapping together three 36" wide panelsand cutting a fourth panel to 12" wide, so that the finished wall was 120" tall and120" wide. The assembly was then placed into a 120" x 120" masonry-linedrestraining frame and screwed into 2" x 2" x 1/8" steel angle to secure it along theperimeter on both faces.

25 GA. galvanized steel furring channels (23/8" wide at the base, 11/8" wide at thecrown and 1" high) were screwed to both sides of the panel wall, spaced vertically at16" o.c. and attached with #8 x 9/16" Tek screws spaced 6" o.c.

An inner layer of 5/8" Type X fire resistant drywall (48" x 120" x 5/8" Firecode, USGypsum Co.) was attached over the furring strips on each side, installedhorizontally, with joints offset 24" from one side of the wall to the other. Thegypsum was attached using #6 x 11/4" self drilling screws, spaced 12" o.c.

An outer layer of 5/8" Type X fire resistant drywall (48" x 120" x 5/8" Firecode, USGypsum Co.) was attached over the inner layers on each side, installed horizontally,with joints offset 24" from one side of the wall to the other. The gypsum wasattached using #6 x 17/8" self drilling screws, spaced 8" o.c. All joints and screwheads on both sides of the wall were then covered with paper and/or gypsum jointcompound in the normal manner. The unexposed surface of the wall was theninstrumented with eleven thermocouples as indicated in Appendix B.

TEST RESULTS AND OBSERVATIONS

The wall assembly was placed in front of the Laboratory’s test furnace onSeptember 16, 1998. The ambient temperature at the start of the test was 72°F,with a relative humidity of 90%. Throughout the fire test, the pressure differentialbetween the inside of the furnace (measured at a point 1/3 of the way down from thetop center of the wall specimen) and the laboratory ambient air was maintained at -0.03 inches of water column, which resulted in a neutral pressure at the top of thetest article.

Observations made during the test are as follows:

Time ( min:sec ) Observation

0:00 Furnace fired at 8:52 a.m.0:32 Gypsum paper turning brown.1:22 Gypsum paper ignited.1:55 Gypsum paper fully consumed.3:57 Paper tape flaking and falling from the joints.

The test article was then exposed to the standard hose stream test at a nozzlepressure of 30 psi, from a perpendicular distance of 20 feet, for 60 seconds. The twolayers of gypsum wallboard on the exposed side of the panel were removed by thewater stream. The steel facer on the exposed side was scorched, but still containedthe surface coating and was not wrinkled by the heat. The water did not penetratethe wall, so the hose stream test was successful.

A table showing the maximum temperatures reached on each of the unexposed sidethermocouples during the 60 minute fire exposure is presented below:

None of the unexposed face thermocouples exceeded an increase in temperature of325°F and their average did not exceed an increase of 250°F.

During the fire test, the wall was measured for deflection at three points along ahorizontal line at mid-height: at 30" (position #1), 60" (position #2) and 90" (position#3) from the left side of the wall. Measurements were made from a taught string tothe wall surface at each location.

Calculation of Time Correction

The E119 standard requires that a correction factor be applied for variation of thefurnace exposure from that prescribed, where it will affect the classification. Thiscalculation has been determined, as indicated below, to be less than 30 seconds, and
