INI'RODUC170N <br /> Thi� report is a pnesentation of resulis nf a surface flammabilifiy best on a mat+erial submit#+ed by 3M <br /> Commercial Graphics,St.Paul,Minnesota. <br /> The test was conducbed in accordance with the AS'I'M lnbematioa�al fire-test response standard E84-13a, <br /> Srtrface Burning Chm,acteristics of 8uilding Malerials,sometimes refernd to as the Sbeiner tunnel best.t�STM <br /> E84 iu� an American National Standard (ANSn and has been approved for � by agencies of the <br /> Department of Defense.The ASTM 884 test method is the teehnical equivalent of UI.No.723.The best is <br /> applicable bo exposed interior aurfaces such as walls and oeilings.The test is conducted with ti�e specimen <br /> , in the ceiling posifion with the surface to be evaluaied face down b�ward the igniiion source. Thus, <br /> speeimens shall eikher be self-supporting by its own struchiral quality,held in place by added supports <br /> alc�g the test surface,or secured from the back side. <br /> This standard is used to measure and d�cribe the response of materiais, products, or assembliea to heat <br /> and Rame under oontrolled conditions, but dces not by itsdf incorporate all factors required for fire- <br /> hazard or fire-risk assessment of�e mat�rials,products,or assemblies under ach�al frre wnditions. <br /> Pusros� <br /> The purp�e of the t�e�is to provide only the comparative measurements of surface flame spread and <br /> smoke develc�pme�t uf materials with that of select grade red oak and 8ber��reinforced cement board, <br /> Grade lI,under specific fire exposure conditiona.The t�est expo�es a nomina124foot long by 20-iach wide <br /> best apecimen to a controlled air flow and flaming fire adjusbed to spread the IIame along the entire lengdl <br /> of a red oak specimen in 5�minut�ees.During tfie 10-mirnite test duration,flam�p read over the eamen <br /> surEace and density of t!u resulting smoke aze measured and remrded.Test resulta are celcula�relative <br /> to red nak,which has an arbitrary rahing of�00,and fiber-reinforced cement bo�rd,Grade II,which has a <br /> rati�g vf 0. <br /> The test resulis are expressed as Ftame Spread Index and Smoke Developed Index. The Flame Spresd <br /> index is de6ned in AS7'M S 176 as"a number ar dassi6cation indicating a comparative measure derived <br /> fi�► observations made during the progress of the boundary of a zone af flame under de�ined test <br /> cv��diticros." The Smoke Developed Index, a term speafic fio ASTM E84, is def{ned as "a number or <br /> classi8cafion indieating a comparative measure derived from smoke obseurat�on data collec�ed during <br /> the Mat for surface burning characberistics." There is not necEssarily a relationship between t�he twu <br /> measurement�s. <br /> The method does not provide for measurement oF heat transmission through the surface tested,the effect <br /> of aggravabed iteme spread behevior of an assembly resulting from the proximity vf combustibl� v�alls <br /> and a�il�ngs,or classifying a maberial as noncombustible solely by means of a Flame Sgread Index. <br /> The zero reference and other parameters critical to furnac�e operation are veri6ed an the day of d�e best by <br /> canducting a 1Q-minute test using 1/4-incfi fiber-reinforced cement board,Grade II. Periadic tests using <br /> NOFMA cerdfied 23/32-inch seleet grade red oak FIooring provide daha for the 700 reference. <br /> TEST SA1N!'LE <br /> The test sample, selected by the dlen�, was identified as 3M'�Envisioa'*' Print Wrap Film 480Cb3, a <br /> self-adh�ring fi1m (Lot #H13048) with a tofial thiekt�ess of U.004". Three best panels, each measuring two <br /> fieet wide by dght feet in length, were prepared by adhecing the material to S/S-inch thick Type X <br /> gypsufn baard complying wit�ASTMSpec�flcation C 1396.The sampie wa�applied M the smoot�t side of <br /> the gy�psum wallboard using the self-adheriaB Pr'�P�'ties of khe sarnple,actd smoothed with a brush and <br /> roller.
