16、estimated quantity of bitumenremaining on the deck.4.5 If practicable, return the cut membrane specimen to itsoriginal location in the roof. Make adequate repairs to theroofing system, using at least the same number of felt plies asthe original roof membrane after testing.5. Procedure5.1 Remove insu
17、lation 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 specimen from three differ-ent measurem
18、ents 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 and skips or dry spots between

Calculation (See Table 1 for Form and SampleComputation)6.1 Calculate the mass (weight) per unit area of the originalspecimen by dividing the
20、 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 inthe original specimen by divid
21、ing 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 felt mass per unit areaby the numbe
22、r of plies (6.2).
