Significance and Use

18、3.1 These test methods are used for sampling and testing modified bitumen sheet materials. Property requirements, determinedby these test methods, are found in the following product standards: Specifications D6162, D6163, D6164, D6222, D6223, D6298,and D6509.4. Sampling4.1 From each shipment or frac

19、tion thereof, select at random a number of rolls equal to one half the cube root of the total numberof rolls in the lot. If the calculated number is fractional, express it as the next highest whole number. For convenience, a tableshowing the number of rolls to be selected from the lots of various si

20、zes is given in Test Method D146. When mutually agreedupon by the concerned parties, other sampling frequencies may be used and reported within the framework of these procedures.The minimum sample shall consist of five rolls. The rolls so selected constitute the representative sample used for all su

21、bsequentobservations and tests pertaining to the lot of material being examined.5. Conditioning5.1 Unless otherwise specified, condition test specimens for a minimum of 4 h at 23 6 2C 73.4 6 3.6F and 50 6 5 %relative humidity before testing.6. Thickness6.1 The thickness measuring device shall be a m

22、icrometer of the dial or digital-electronic type capable of measuring dimensionsto an accuracy of 0.1 mm 0.004 in. The micrometer shall be equipped with a flat, circular presser foot with a diameter greateror equal to 9.5 mm 0.375 in. and less than 32 mm 1.25 in. During operation, contact between th

23、e presser foot and the specimenshall be maintained either by a spring inside the micrometer or by the weight of the presser foot and attached parts.6.2 One specimen shall be obtained from each of the rolls selected in accordance with the Sampling section of these testmethods. Each specimen shall be

24、at least 700 mm 2712 in. in length by the manufactured width of the roll. Five measurementsof sheet thickness and five measurements of selvage thickness shall be taken on each specimen. All measurements shall be takenin a manner that requires the presser foot to contact the side of the sheet that is

25、 intended to be exposed when applied in accordancewith the manufacturers instructions.NOTE 1When measuring products with particulate surfaces, wiping particles from the presser foot between measurements is recommended to preventbuildup of particles that may result in inaccurate measurements.6.2.1 Ta

26、ke five measurements of the sheet thickness along a line parallel to cross-machine direction. Two of the fivemeasurements shall be taken 150 615 mm 6 6 0.5 in. from each edge of the specimen. The remaining three measurements shallbe taken at three points approximately equally spaced (615 mm 0.5 in.)

27、 between these two points. Refer to Fig. 1 for anillustration of the sheet thickness measurement locations.6.2.2 Take five measurements of the selvage thickness along a line parallel to machine direction. The measurements are to betaken midway between the surfacing edge and the sheet edge or, in the

28、 case of smooth products, midway between the laying lineand the sheet edge, and spaced 150 6 15 mm 6 6 0.5 in. apart. Refer to Fig. 1 for an illustration of the selvage thicknessmeasurement locations.6.3 For each specimen, report the individual point measurements, mean, and standard deviation for bo

29、th the sheet thickness andselvage thickness measurements.D5147/D5147M 1426.4 Calculate the mean of the specimen sheet thickness means and report this value as sample sheet thickness. Calculate themean of the specimen selvage thickness means and report this value as sample selvage thickness. Unless o

30、therwise required bythe standard product specification that references these test methods, sample sheet thickness and sample selvage thickness are thevalues used for comparison with the product specification requirements.6.5 Precision and Bias:6.5.1 Interlaboratory Test ProgramInterlaboratory studie
