Thickness5.1 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 mi-crometer shall be equipped with a flat, circular presser footw

16、ith a diameter greater or equal to 9.5 mm (0.375 in.) and lessthan 32 mm (1.25 in.). During operation, contact between thepresser foot and the specimen shall be maintained either by aspring inside the micrometer or by the weight of the presserfoot and attached parts.5.2 One specimen shall be obtaine

17、d 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 selvagethickness shall be taken on each spec

18、imen. 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, wipingparticles from the presser foot

19、 between measurements is recommended toprevent buildup of particles that may result in inaccurate measurements.5.2.1 Take five measurements of the sheet thickness along aline parallel to cross-machine direction. Two of the fivemeasurements shall be taken 150 615 mm (6 6 0.5 in.) fromeach edge of the

20、 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.5.2.2 Take five measurements of the selvage thickness alonga line paralle

21、l 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 15 mm (6 60.5 in.) apart. Refer to Fig. 1 for an illustration of the selvagethickness mea

27、e precision information given belowfor sheet thickness and selvage thickness in the units ofmeasurement (millimetres) is for the comparison of two testresults, each of which is the average of five test determinations.5.5.3 Precision:Selvage Thickness Sheet ThicknessTest range 1.952 to 2.706 mm 1.959

Specimens shall be 25 mm (1.0 in.)wide by a minimum of 150 mm (6.0 in.) long for sheetmaterials having an ultimate elongation of 75 % or less at18C (0F). Specimens shall be 12.5 mm (0.5 in.) wide by aminimum of 100 mm (4.0 in.) long

32、for materials having anultimate elongation of greater than 75 % at 18C (0F).6.1.2 Procedure:6.1.2.1 Condition each specimen at least 2 h at the selectedtest temperature. If conditioning is done outside the machineclamps, allow the specimen to equilibrate at the testingtemperature for at least 15 min

34、the specimen without slipping. The initialclamp separation shall be 75 6 2 mm (3.0 6 0.1 in.) for sheetmaterials having an ultimate elongation of 75 % or less at18C (0F), and 50 6 2 mm (2.0 6 0.1 in.) for sheet materialshaving an ultimate elongation greater than 75 % at 18C(0F).6.1.2.4 Maintain a ra
