Calculation (See Table 1 for Form and SampleComputation)6.1 Calculate the mass (weight) per unit area of the originalspecimen by dividing the specimens weight by its area (andmultiplying by 100 if U.S. customary units are used).6.2 Divide the sum of

23、the individual felt areas by the area ofthe original specimen, and record as the “number of plies.”6.3 Calculate the mass per unit area of the saturated felts inthe original specimen by dividing the individual felt areas bythe area of the original specimen, and then multiplying by thefollowing value

24、s. Add the masses per unit area for each felt tofind the total mass per unit area of the original felts. If all theplies are the same, multiply the assumed felt mass per unit areaby the number of plies (6.2). Use manufacturers informationfor components not within the scope of the following specifi-c

27、e II.6.3.6 Specification D 3158Use 1416 g/m2(29 lb/100 ft2).6.4 Calculate the total interply bituminous material per unitarea by subtracting the mass of the saturated felts (6.3) andassumed mass of insulation (5.1), if any, from the mass per unitarea of the original specimen (6.1). Add the estimated

28、 mass ofbituminous material remaining on the deck (4.2.2), if any; orsubtract the weight of any bitumen, felt, or coating contributedby the insulation if insulation was removed, in consistent units.6.5 Calculate the average interply bituminous material perunit area by dividing the total mass per uni

If there is no bitumen belowthe bottom ply, divide the mass of the bitumen by the numberof plies minus one.6.6 Calculate the total membrane mass per unit area byadding the mass per unit area of the felts and the total interplybitumen.6.7 Calculations
