40、 holder.6.5.7.3 After cutting specimen to the correct size, drill ahole through the thickness of the specimen at the center. Use adrill press and steel drill bit described in 6.5.3.4.6.5.7.4 Insert drilled specimen level with top edge ofspecimen holder. If required, provide a shim of unfacedfibergla
41、ss (approximate 0.5 lb/ft3) under the specimen that iscut to fit holder and center drilled to align with specimen.Carefully cut excess material extending above the top edge ofthe specimen holder. A reciprocating electric knife or saw hasbeen found suitable. Take care that the center drilled hole isf
42、ree of debris and if the shim pad is used, that the hole isaligned through specimen and pad.6.5.7.5 Weigh specimen and specimen holder, subtractweight of empty specimen holder and fiberglass shim if used.Record this as the starting weight of the specimen, (W1).Calculate the density of the specimen t

44、 with the specimensurface. Place the specimen in the test chamber and allowburning of the cigarette to proceed undisturbed for at least 1 h,after which, allow specimen to remain until there is noevidence of heat or smoke and the bottom of the specimenholder is cool to the touch.6.5.7.7 After the spe
45、cimen has cooled to less than 25C(77F), weigh to the nearest 0.2 g and subtract the tare weightdetermined in 6.5.7.1 to arrive at the final net weight, ( W2).6.5.8 CalculationCalculate percent weight loss as fol-lows:WL 5 $W12 W2%/W1! 3 100 (1)where:WL = weight loss, %,W1= weight of specimen before
46、test, g (oz), andW2= final weight of specimen at completion of test, g(oz).6.5.9 RetestIf all three specimens pass, the insulationpasses. If more than one fails, the insulation is rejected. If anyone of the three specimens should fail, conduct a retestconsisting of three additional specimens. Should
47、 one of thethree retest specimens fail, the insulation is rejected.6.5.10 Results of test: Pass/Fail.6.5.11 Precision and Bias The precision and bias of this testmethod has not been determined.6.6 Fungi Resistance:6.6.1 ScopeThis test method covers the determination ofthe amount of resistance to the
