Scope
1.1 These test methods cover procedures for testing rigid electrical insulation normally manufactured in flat sheet or plate form. They are generally used as terminal boards, spacers, voltage barriers, and circuit boards.
Note 1—For tests applying to vulcanized fibre reference should be made to Test Methods D 619.
Note 2—This standard resembles IEC 60893-2, Specification for Rigid Industrial Laminated Sheets Based On Thermosetting Resins for Electrical Purpose, Methods of Tests.1.2 The test methods appear in the following sections:
| Test | Sections | ASTMTestMethod |
| Acetone extractable matter | 83 to 84 | D 494 |
| Arc resistance | 47 | D 495 |
| Ash | 56 to 60 | ... |
| Bonding strength | 49 to 54 | ... |
| Burning rate and flame resistance | 61 to 75 | ... |
| Compressive strength | 25 | D 695 |
| Conditioning | 4 | D 6054 |
| Dissipation factor | 34 to 40 | D 669 |
| Dielectric strength | 28 to 33 | D 149 |
| Expansion (linear thermal) | 76 | D 696 |
| Flexural properties | 12 to 24 | D 790 |
| Hardness (Rockwell) | 55 | D 785 |
| Insulation resistance and resistivity | 41 to 46 | D 257 |
| Permittivity | 34 to 40 | D 150 |
| Resistance to impact | 26 | D 256 |
| Tensile properties | 7 to 11 | D 638 |
| Thickness | 5 to 6 | D 374 |
| Tracking resistance | 48 | D 2132 |
| Warp or twist | 77 to 82 | ... |
| Water absorption | 27 | D 570 |
1.3 The values stated in inch-pound units are to be regarded as the standard. The metric equivalents of inch-pound units given in these test methods may be approximate.
1.4 This is a fire-test-response standard. See Sections 61 through 75, which are the procedures for burning rate and flame resistance.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in 31.1 and 61.5.
