hutnidity at 50 t 5 getc�nt Far testing, the panels were plaoed end-to-end on the ledges of the tunnel <br /> fumace and the test conducted with no awdliary support mechanism. <br /> TEST RESULTS <br /> 'f'he Ue.st results,calculabed an the basis of observed tlame propagati�and the i�begrated area under the <br /> recarded smoke density curve,are presented below.The Flame 5pread Index obtained in E84 is raunded <br /> tv the nearest number divisible by five. Smake Devel�ped lndiees are raunded to the nearest number <br /> dirrisible by five unless�e lndex is greaber than 200.In tfiat case,the Sm�ke Developed Index is rounded <br /> to�e nearest 50 poin�.The flame spread and smdce development dam are pr�senbed graphically at the <br /> end of this report. <br /> Test S ecimen FJame S read Iadex moke ev <br /> i er- in orce ement oar ,Grade II 0 <br /> Red E�k Flaxin 1� 100 <br /> 3M'*�EnvisionT°'Prlut Wra Film 480Cv3 10 0 <br /> OBS6RVA'f10NS <br /> 5pecimen ignition over the burners occurred at 0.78 minute.
