Significance and Use3.1 These test methods are used for sampling and testingmodified bitumen sheet materials. Property requirements, de-termined by th

16、ese test methods, are found in the followingproduct standards: Specifications D6162, D6163, D6164,D6222, D6223, D6298, and D6509.4. Sampling4.1 From each shipment or fraction thereof, select at randoma number of rolls equal to one half the cube root of the totalnumber of rolls in the lot. If the cal

17、culated number is fractional,express it as the next highest whole number. For convenience,a table showing the number of rolls to be selected from the lotsof various sizes is given in Test Method D146. When mutuallyagreed upon by the concerned parties, other sampling frequen-cies may be used and repo

18、rted within the framework of theseprocedures. The minimum sample shall consist of five rolls.The rolls so selected constitute the representative sample usedfor all subsequent observations and tests pertaining to the lot ofmaterial being examined.5. Conditioning5.1 Unless otherwise specified, conditi

Thickness6.1 The thickness measuring device shall be a micrometerof the dial or digital-electronic type capable of measuringdimensions to an accuracy of 0.1 mm 0.004 in. The microm-eter shall be eq

20、uipped with a flat, circular presser foot with adiameter greater or equal to 9.5 mm 0.375 in. and less than 32mm 1.25 in. During operation, contact between the presserfoot and the specimen shall be maintained either by a springinside the micrometer or by the weight of the presser foot andattached pa

21、rts.6.2 One specimen shall be obtained from each of the rollsselected in accordance with the Sampling section of these testmethods. Each specimen shall be at least 700 mm 2712 in. inlength by the manufactured width of the roll. Five measure-ments of sheet thickness and five measurements of selvageth

22、ickness shall be taken on each specimen. All measurementsshall be taken in a manner that requires the presser foot tocontact the side of the sheet that is intended to be exposedwhen applied in accordance with the manufacturers instruc-tions.NOTE 1When measuring products with particulate surfaces, wi

23、pingparticles from the presser foot between measurements is recommended toprevent buildup of particles that may result in inaccurate measurements.6.2.1 Take five measurements of the sheet thickness along aline parallel to cross-machine direction. Two of the fivemeasurements shall be taken 150 615 mm

24、 6 6 0.5 in. fromeach edge of the specimen. The remaining three measurementsshall be taken at three points approximately equally spaced(615 mm 0.5 in.) between these two points. Refer to Fig. 1for an illustration of the sheet thickness measurement loca-tions.FIG. 1 Location of Thickness Measurements

25、D5147/D5147M 11a26.2.2 Take five measurements of the selvage thickness alonga line parallel to machine direction. The measurements are tobe taken midway between the surfacing edge and the sheetedge or, in the case of smooth products, midway between thelaying line and the sheet edge, and spaced 150 6

26、 15 mm 6 60.5 in. apart. Refer to Fig. 1 for an illustration of the selvagethickness measurement locations.6.3 For each specimen, report the individual point measure-ments, mean, and standard deviation for both the sheet thick-ness and selvage thickness measurements.6.4 Calculate the mean of the spe

Unless otherwiserequired by the standard product specification that referencesthese test methods, sample sheet thi

28、ckness and sample selvagethickness are the values used for comparison with the productspecification requirements.6.5 Precision and Bias:6.5.1 Interlaboratory Test ProgramInterlaboratory stud-ies were run in which randomly drawn test specimens of threematerials (sand-surfaced SBS-modified base sheet,

29、 fiberglass-reinforced SBS-modified cap sheet, and polyester-reinforcedAPP-modified cap sheet) were tested for sample sheet thick-ness and sample selvage thickness in each of eleven laborato-ries. Each laboratory tested two sets of five specimens of eachmaterial. Practice E691 was followed for the e

30、xperimentaldesign and analysis of the data. Details of the experiment areavailable in ASTM Research Reports RR:D08-1010 andRR:D08-1011.3, 46.5.2 Test ResultThe precision information given belowfor sheet thickness and selvage thickness in the units ofmeasurement (millimetres) is for the comparison of

31、 two testresults, each of which is the average of five test determinations.6.5.3 Precision:Selvage Thickness Sheet ThicknessTest range 1.952 to 2.706 mm 1.959 to 3.824 mmr, 95 % repeatability limit(within a laboratory)0.088 mm(0.040 to 0.157 mm)0.048 mm(0.039 to 0.054 mm)R, 95 % reproducibility limi

The respectivestandard deviations among test results may be obtained bydividing the above limit values by 2.8.6.5.4 Bia
