HAMILTON ST. tD" I. INTRODUCTION - ( J This report is a presentation of the results of the tunnel test on a carpet submitted for testing by Bigelow-Sanford, Inc. F The test was conducted in accordance with the provisions of the American e i Society for Testing and Materials Standard Method of Test E 84-79a, "Surface s Burning Characteristics of Building Materials", also known as the Steiner Tunnel Test. This test method is similar to ANSI 2. 5, NFPA No. 255, UBC No. 42-1, and UL No. 723. s{ This standard should be used to measure Ad describe the pr,operMn of £ I materials in response to heat and flame under controlled laboratory conditions. It should not be used for description, appraisal, or regulation of the fire hazards of materials under actual fire conditions. There are no considornLlou> made for results that may be obtained if the Specimen beinl; t.vulunted were tested in combination with other building materials. 1 ` The fire performance of any material in the light of present knowledge cannot be evaluated on the basis of any one test. The test results presented t here apply only- to the specimen tested and are not necessarily indicative of : apparent identical or similar materials. All test data are on file and are available for review by authorized persons. t,. II. PURPOSE The tunnel test method is intended to compare the sur0ce fl.amespread and i smoke developed measurements in relation to asbestos-cement board and select a; grade red oak flooring surfaces. A material is exposed to a flaming fire exposure, adjusted to spread the flame along the entire length of a red oak specimen in 5.50 minutes during a 10-minute test duration, while flamespread 6. over its surface and density of the resulting smoke are measured and. recorded. 9 Test results are computed relative to the red oak specimen, which has a 100 rating, and asbestos-cement board, which has a 0 rating, and are expressed as Flamespread Classification and Smoke Developed. III.

PREPARATION AND CONDlTIONING.,OF TEST_ SPECIMEN i The specimen being evaluated was adhered to Type U, one-quarter inch asbestos-cement board. A.P. Green Sairmix-7 High Temperature Bonding Mortar was troweled onto the back of the specimen using a 3/32" x 3/32" notched k ." trowel. The prepared specimen was placed on the asbestos-cement board and rolled with a 100-pound carpet roller to assure a good bond. The specimens were dead stacked overnight, transferred to a storage rack, and conditioned in an atmosphere maintained between 70' and 75' F temperature and 45 to 55 percent relative humidity. V. TEST PROCEDURE The test was conducted on February 28, 1980. The Accu veferooen and ocher data critical to furnace operation were verified by conducting a 10-miuute test with one-quarter inch asbestos-cement board on the day of the test. Periodic tests using NOFMA certified select grade red oak flooring provided data for Lho 100 reference. The material was then tested In accordance with the standard 1 procedure. VI. TEST RESULTS The .test results, computed on the basis of observed flame (rout ndvnnce and the integrated area under the recorded curve of the smoke density apparatus , Eare presented in the following table.

BOX 94 - 407 CENTRAL AVE. - DALTON, GA. 30720 - 404 ,1278-393M ,i INTRODUCTION This report represents results of a Test for Critical Radiant Flux 1 of a Carpet Flooring System submitted by Bigelow-Sanford, Inc. . h , This test, also known as the Flooring Radiant Panel, measures the critical fi a radiant flux at flame out of horizontally mounted complete .flooring ;w N systems exposed to a flaming ignition source in a graded radiant haat i energy environment intended to simulate actual conditions that have been observed and defined in full-scale exp w:.iment:s. The to:it hl rtppl.Ienh h! only to floor covering systems which duplicate or simulate accepted installation practices. Tests on individual components of a floor system are of limited value and are not valid for evaluation of the s entire flooring system. The test results apply only to the specimens tested and are not necessarily indicative of apparent identical or ,similar materials. All test data are on`file and are available for review by authorized persons. PURPOSE The Flooring Radiant Panel test measures the level of incident radiant heat energy on the floor covering system at the most distant j flame out point, and is expressed as Critical Radiant Flux .i.n watts per square centimeter. It provides a basis for estimating one aspect of flame spread behavior for floor covering systems installed in corridors or exitways of buildings. The imposed radiant flux simulates thermal radiation' levels likely to impinge on the. floor of a corridor whose erg COM M a H C I0 00 U 41 ,. w i C3) upper surfaces are heated by flames" and/or hot gases from a fully developed nJf fire in an adjacent room or compartment. r r TEST PROCEDURE k A minimum of three (3) sets of the floor covering systems to be evaluated must be tested. A specimen measuring 20 centimeters by 1.00 . centimeters is mounted in a horizontal specimen holder In Lho toot chamber. A gas/air fueled radiant heat energy panel is mounted in the i chamber at a 30° angle to the horizontal specimen plane. The radiant I panel generates a radiant energy flux distribution ranging along the 100 centimeter length of the specimen holder for a maximum of approximately r i 1.0 watts per square centimeter to a minimum of 0.1 watts per squame centimeter. The test is initiated by an open flame from a pilot burner t ` that is brought into contact with the specimen for 10 minutes, or until !i the flame goes out. For specimens that continue to burn after ten i minutes, the test is continued until flame out. The specimen is then Ii removed from the test chamber and the point of farthest flame front advance is measured. The critical radiant flux is than calculated from the flux profile curve determined during calibration. TESTING The floor covering system submitted was tested on March '30, 1.979. The critical radiant flux of an inorganic millboard dummy specimen was checked at the 40 cm mark on the day of the test. Cr:i.t:ical radiant flux of 0.5 + 0. 2 watts per square centimeter indicated proper operation of r i x � r l Y, I'VaIIIIIIIIERCIAh 'F1d _. a ti. the test equipment. The flooring s stem ,was then tested within _ g y � parameters outlined in the published standard. < ?
