19、erty requirements, de-termined by these test methods, are found in the followingproduct standards: Specifications D6162/D6162M, D6163/D6163M, D6164/D6164M, D6222/D6222M, D6223/D6223M,D6298/D6298M, and D6509/D6509M.4. Sampling4.1 From each shipment or fraction thereof, select at randoma number of rol

20、ls equal to one half the cube root of the totalnumber of rolls in the lot. If the calculated 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/D146M. Whenmutu

21、ally agreed upon by the concerned parties, other samplingfrequencies may be used and reported within the framework ofthese procedures. The minimum sample shall consist of fiverolls. The rolls so selected constitute the representative sampleused for all subsequent observations and tests pertaining to

22、 thelot of material being examined.5. Conditioning5.1 Unless otherwise specified, condition test specimens fora minimum of4hat236 2C 73.4 6 4F and 50 6 5%relative humidity before testing.6. Thickness6.1 The thickness measuring device shall be a micrometerof the dial or digital-electronic type capabl

23、e of measuringdimensions to an accuracy of 0.1 mm 0.004 in. The microm-eter shall be equipped 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 eith

24、er by a springinside the micrometer or by the weight of the presser foot andattached parts.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 widt

25、h of the roll. Five measure-ments of sheet thickness and five measurements of selvagethickness 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

26、manufacturers instruc-tions.NOTE 1When measuring products with particulate surfaces, wipingparticles 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 par

27、allel to cross-machine direction. Two of the fivemeasurements shall be taken 150 6 15 mm 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

28、 of the sheet thickness measurement loca-tions.6.2.2 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 th

29、e sheet edge, and spaced 150 6 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 pointmeasurements, mean, and standard deviation for both the sheetthickness and selvage thickness measurements.6.4 Cal

30、culate the mean of the specimen sheet thicknessmeans and report this value as sample sheet thickness. Calcu-late the mean of the specimen selvage thickness means andreport this value as sample selvage thickness. Unless otherwiserequired by the standard product specification that referencesthese test

31、 methods, sample sheet thickness and sample selvagethickness are the values used for comparison with the productspecification requirements.6.5 Precision and Bias:6.5.1 Interlaboratory Test ProgramInterlaboratory studieswere run in which randomly drawn test specimens of threematerials (sand-surfaced

32、SBS-modified base sheet, 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 E69

33、1 was followed for the experimentaldesign 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) i
