18.1 This test method provides useful engineering information for evaluating the mechanical behavior of rigid electrical insulation at elevated temperature. When the proper exposure and test temperatures are chosen, depending on the material and end-use operating temperature, use the test method as one means of indicating relative thermal degradation of rigid insulating materials.
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.
1.2 Use Test Methods D619 (withdrawn) or Specification D710 for tests applying to vulcanized fibre.
1.3 Some of the test methods contained in this standard are similar to those contained in IEC 60893-2, which applies to rigid industrial laminated sheets based on thermosetting resins for electrical purposes.
1.4 The test methods appear in the following sections:
Test | Sections | ASTM |
Acetone extractable matter | 83 to 84 | D494 |
Arc resistance | 47 | D495 |
Ash | 56 to 60 | ... |
Bonding strength | 49 to 54 | ... |
Burning rate and flame resistance | 61 to 75 | ... |
Compressive strength | 25 | D695 |
