Detail Requirements6.1 The materials covered by this

21、specification shall con-form to the requirements prescribed in Table 1 and Table 2when tested by the procedures specified herein. Table 2 liststhose tests requiring a specimen molded as described in 9.1.7. Sampling7.1 Sampling shall be statistically adequate to satisfy therequirements of 10.4.8. Num

22、ber of Tests8.1 One set of test specimens as prescribed in Section 9shall be considered sufficient for testing each sample. Theaverage result of the specimens tested shall conform to therequirements of this specification.9. Test Methods9.1 Test Specimens:9.1.1 Prepare a molded sheet 1.50 6 0.25-mm (

23、0.06060.010-in.) thick. Use a picture-frame-type chase having asuitable blanked-out section and thickness to produce thedesired sheet. Use clean aluminum foil, 0.13 to 0.18 mm (0.005to 0.007 in.) thick, in contact with the resin.Ahigh temperaturemold release agent may be sprayed on the aluminum foil

24、 tohelp prevent the foil from sticking to the sheet. Use steelmolding plates at least 1.0 mm (0.040 in.) thick and of an areaadequate to cover the chase.9.1.2 Lay down and smoothly cover one plate with a sheetof aluminum foil. Place the mold chase on top of this assembly.Place within the mold chase

25、sufficient molding material toproduce the required sheet in such manner that the polymercharge is a mound in the middle of the chase. Place a secondsheet of aluminum foil on top of the granules and add the topmold plate. Place the assembly in a compression molding presshaving platens that have been

26、heated to 380 6 5C (716 610F).9.1.3 Bring the press platens to incipient contact with themold assembly. Hold for 2 to 4 min without pressure. Applyapproximately 1 MPa (145 psi) and hold for 1 to 1.5 min. Thenapply 2 to 4 MPa (290 to 580 psi) and hold for 1 to 1.5 min.Maintain the press at 380 6 5C (

27、716 6 10F) during thesesteps. Remove the assembly from the press and place betweentwo 20 6 7-mm (0.75 6 0.25-in.) steel plates whose tempera-ture is less than 40C (104F).9.1.4 When the sheet is cool enough to touch (about 50 to60C (122 to 140F), remove the aluminum foil from thesheet. (If the sheet

28、is allowed to cool to room temperature, thealuminum foil cannot be pulled free.)9.2 Conditioning:9.2.1 For tests of specific gravity, tensile properties, andelectrical properties, condition the molded test specimens inaccordance with Procedure A of Practice D618 for a period ofat least 4 h prior to

29、test. The other tests require no conditioning.6Available from American National Standards Institute (ANSI), 25 W. 43rd St.,4th Floor, New York, NY 10036, http:/www.ansi.org.7See ASTM Form and Style Manual.TABLE 1 Detail Requirements for Test on Molding and Extrusion MaterialsTypeITypeIITypeIIITypeIV
