RECOMMENDATIONS Fiberboard fabrication and finishing techniques, such as crease bending, scoring, forming, perforating, and the application of barrier coatings or paints, will modify the characteristics of the producers basic mate
14、rial. Consequently, it is recommended that separate but related specifications be established for (1) the properties of the basic product and (2) the finished processed material. 5. CONDITIONING Tests for material classification and for arbitration purposes shall be made on material conditioned to a
15、 constant weight in a controlled atmosphere of 21 C 1 C (70 F 2 F) and 50 or 65% relative humidity (as specified by the user). Quality control tests can be conducted on unconditioned specimens unless otherwise specified by the user. 6. THICKNESS Thickness shall be measured by a micrometer having two
16、 plane, parallel faces, the smaller of which should be circular and 161 - 212 mm2(0.25 - 0.33 in2) in area. When the specimen is clamped between the faces, it should be under a steady pressure of 48.23 - 62.0 kPa (7.0 - 9.0 psi). The graduations of the dial face should be such as to permit estimatin
17、g the thickness to at least 0.013 mm (0.0005 in). The sample should be comprised of at least three representative specimens, each of which should be tested in four separate places. The test should be made by placing the specimen between the jaws of the micrometer and lowering the pressure foot gentl
18、y upon the surface of the specimen, taking care that the edge of the foot is at least 0.25 in (6.3 mm) from the edge of the specimen. The average thickness should be reported in decimals of an inch (millimeter) to the nearest 0.013 mm (0.0005 in) and may be supplemented by maximum and minimum readin
19、gs. Fundamental technique and apparatus used shall be similar to those of ASTM D 645. NOTE: Specimens cut for dimensional stability tests are satisfactory for these measurements.

Dimensions shall be measured accurately to the nearest 0.25 mm (0.01 in). Three representative specimens shall be weighe
21、d and the average computed and reported in pounds per 1000 ft2or grams per square meter. 8. DENSITY Density in pounds per cubic foot (kilograms per cubic meter) shall be computed using data obtained from the average thickness and weight report. 9. BURSTING STRENGTH The bursting strength shall be det
22、ermined using the conventional power-driven hydraulic type machine. The average value to the nearest 34.5 kPa (5 psi) obtained by making five bursts on each side of three specimens is to be reported. Fundamental technique and apparatus used shall conform to ASTM D 774, Method of Test for Bursting St
23、rength of Paper. 10. COHESIVE STRENGTH This test is designed to measure the force required to rupture a sample of paperboard at the weakest layer. 10.1 Apparatus Jumbo Mullen Tester (Figure 1): a. Brass disks, 1.6 mm (0.063 in) thick and 60.71 mm (2.390 in) diameter b. Annular brass disks, 1.6 mm (0
24、.063 in) thick, 76 mm (3 in) outer diameter, and 34.93 mm (1.375 in) inner diameter c. Steel sleeve, approximately 69.9 mm (2.75 in) inside diameter, 13 mm (0.5 in) high, and 3.18 mm (0.125 in) thick d. Means of cleanly cutting an annular sample of 60.71 mm (2.390 in) outer diameter and 34.93 mm (1.
25、375 in) inner diameter 10.2 Procedure Cut a 356 x 76 mm (14 x 3 in) sample of the board to be tested. Cover each side with a strip of 76 mm (3 in) double-face, pressure-sensitive tape or equivalent without peeling the protective liner, and die cut four annular specimens for testing. Peel one of the
26、protective liners from each sample and press lightly to one of the solid disks; then peel the other liner and place an annular disk on the other side, using the hole in each for alignment.

27、ermitted without license from IHS-,-,-SAE J315 Reaffirmed MAR2010 Page 4 of 10FIGURE 1 Press the sample between the disks under about 690 kPa (100 psi). This can be done using the sample clamp of the Mullen tester itself. A pile of a dozen samples may be pressed at one time. Place one sample on the
28、lower platen of the Mullen tester with the annular disk down and centrally located so that the hole in the disk is aligned with the hole in the platen. Place the steel sleeve upon the annular disk and clamp in place with the upper platen. Operate the tester until the expansion of the diaphragm again
29、st the solid disk ruptures the sample. Use the 0 - 1380 kPa (0 - 200 psi) scale. Record the maximum pressure and note the location of the rupture. Failure of the tape bond invalidates a test. Since the area of contact between diaphragm and solid disk varies according to the pressure, do not calculat
30、e the pressure per square inch of sample, but report the results as gage readings, in kPa (psi). However, the area of the sample is exactly 19.4 cm2(3 in2) if the user desires to calculate kPa (psi).

MOISTURE CONTENT The moisture content shall be determined by observing the loss in weight of a 100 x 100 mm (4 x 4 in) specimen (the test specimen may be delaminated to facilitate moisture removal), upon dry
32、ing in an air circulating oven maintained at 102 C 3 C) 215 F 5 F until a constant weight is obtained. The weight loss shall be expressed as percent moisture on the basis of the initial weight of the specimen. For reference purposes, see ASTM D 644, Method of Test for Moisture in Paper. In cases whe
33、re appreciable volatile material other than water is known to exist, the Dean and Stark apparatus may be used. See ASTM D 95, Method of Test for Water in Petroleum Products and Other Bituminous Materials. 12. WATER ABSORPTION The percent of water absorption shall be determined by observing the gain
34、in weight of each of three 100 x 100 mm (4 x 4 in) specimens upon immersion in distilled or deionized water. The test specimens shall be cut with a paper cutter or band saw to prevent delamination of the edges. The specimens shall be weighed to the nearest 0.01 g and then submerged horizontally unde
35、r 25 mm (1 in) of water maintained at 21 C 1 C (70 F 2 F) and at a pH of 7.0 0.5. The samples were removed after periods of 2.5 and 24 h, 5% and visible surface water is removed by wiping or blotting. The specimens shall be immediately reweighed to the nearest 0.01 g. The weight of absorbed water sh
36、all be calculated and the water absorption expressed as percent by weight based on the initial weight. The average value for each time period is reported. 13. THICKNESS SWELL The thickness shall be determined to the nearest 0.025 mm (0.001 in) by averaging four readings taken at the center of each s
37、ide of the water absorption specimen and 25 mm (1 in) from the edge. The caliper reading shall be taken using the same apparatus as described in Section 6 The specimen shall be soaked and treated in the same manner as established in Section 12 Immediately following the tests, the specimen shall be r
38、ecalipered in the same location and manner, and the average reading established for each soaked specimen. The following formula shall be used when calculating the percent of swelling: 100TTTS112 = (Eq. 1) where: S = swelling, % T1 = average thickness before soaking, mm (in) T2 = average thickness af
39、ter soaking, mm (in) 14. WARPAGE The original, wet, and dry warpage shall be determined by the following test methods: 14.1 Original Warpage Prepare three test specimens 305 x 305 mm (12 x 12 in) from three different samples of fiberboard which are representative of a shipment. Lay a specimen on a f
40、lat horizontal surface, and hold a straight edge so that it bridges the specimen in the area of maximum bow. Do not allow the weight of the straight edge to bear on the specimen. Using a steel scale, graduated in 0.25 mm (0.01 in), measure the distance x at the midpoint of the straight edge bridging
41、 the bow. This distance must be measured on a perpendicular line to the straight edge. (See Figure 2.)

44、of perforated metal1so that air can contact specimen(s) on both sides for 24 h at 38 C 1 C (100 F 2 F) and 98% 2% RH. Remove conditioned specimen(s) and perforated metal sheet and allow specimen(s) to remain on perforated metal surface to dry for 30 min at room temperature. Calculate wet warpage as
45、in 15.1. 14.3 Dry Warpage Allow specimen(s) to dry 24 h on the flat perforated metal surface under conditions described in Section 5. Calculate dry warpage as in 15.1. 15. DIMENSIONAL STABILITY The linear expansion and contraction shall be determined in the following manner: Cut three 305 x 305 mm (
46、12 x 12 in) test specimens from three different samples of fiberboard which are representative of a shipment. Inscribe a 254 x 254 mm (10 X 10 in) square on one side of each test specimen. Follow Method A and/or Method B, as required by the material specification, followed by Method C. Method C may
47、also be used individually as a drying test. At the end of the specified exposure period the test specimen shall be removed and the gage lines measured to the nearest 0.25 mm (0.01 in) both with machine direction and across machine direction. Calculate and report the average percent expansion or cont
48、raction of the three specimens. 15.1 Method AExpansion Hang the test specimen(s) in a vertical position in a humidity cabinet maintained at a temperature of 38 C 1 C (100 F 2 F) and a relative humidity of 98% 2% for a period of 24 h. On highly water resistant board, the exposure period may be continued to 7 days. NOTE: The test specimens shall be protected from condensation water droplets by a slanted rustproof metal shield. 15.2 Method BExpansion Place each test specimen between two 305 x 305 mm (12 x
