Scope1.1 This practice is a guide for removing specimens forbuilt-up bituminous roof systems during application, but beforethe application of flood coating and top surfacing, for deter-mining the approximate quantities of the components and thepossibl

4、e presence of moisture, or dry spots between plies, inthe field. Components may consist of:1.1.1 Insulation, when part of the roof membrane system,1.1.2 Plies of roofing felt,1.1.3 Interply layers of bituminous material, and1.1.4 Top coating, if present, before any surfacing aggregatehas been applie

5、d.1.2 This practice is applicable to both 914-mm 36-in. and1000-mm 3938-in. wide felt rolls.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used indepen

6、dently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and

United States14.3 For the purpose of determining the felt spacing,

15、cut a100- by 111-mm 4- by 44-in. rectangular specimen from themembrane, using a template (Fig. 1) placed at right angles tothe long dimension of the felts.4.4 Identify each specimen by location and record thepresence of insulation or the estimated quantity of bitumenremaining on the deck.4.5 If prac

16、ticable, 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 insulation fully from the 300- by 300-mm 12-by 12-in. specimen, if

17、 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 measurements in each direction and weigh.5.2 Measure the individual fe

18、lts 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 layers offelt.5.4 Determine the number of plies and lap spacin

19、g 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 originalspecimen by dividing the specimens weight by its area (andmultiplying by 100 if U.S. c

20、ustomary 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 dividing the individual felt areas bythe area of the original speci

21、men, 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 number of plies (6.2). Use manufacturers informationfor components
