Scope1.1 This practice is a guid

18、ting.5. Procedure5.1 Remove insulation fully from the 300- by 300-mm 12-by 12-in. specimen, if present, being careful to remove as littlebituminous material as possible or leave the insulation in placeand later use manufacturers information to correct for itsweight. Determine the area of the specime

19、n from three differ-ent measurements in each direction and weigh.5.2 Measure the individual felts and calculate the area ofeach ply as in 5.1 (as a result of lapping not all plies will be thesame size as the original specimen).5.3 Visually check along the sample edges for moisturewithin the membrane

20、 and skips or dry spots between layers offelt.5.4 Determine the number of plies and lap spacing by visualexamination of the 100- by 1118-mm 4- by 44-in. specimen,if lap spacing is desired.6. Calculation (See Table 1 for Form and SampleComputation)6.1 Calculate the mass (weight) per unit area of the

21、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 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

22、inthe original specimen by dividing the individual felt areas bythe area of the original specimen, and then multiplying by thefollowing values. 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 fel

23、t mass per unit areaby the number of plies (6.2).
