6.1 This characteristic is useful for specification purposes and has utility as a quality control parameter.
1.1 These test methods cover the evaluation of the characteristics of glass-bonded, natural, or synthetic mica materials intended for use as electrical insulation.
1.2 Glass bonded mica materials are commercially available in both injection molded and compression molded types. These test methods are applicable to both types except for tensile strength methods. (See Section 41.)
1.3 The test methods appear in the following sections:
| Test Method | Section | ASTM Test Method |
| Arc Resistance | 57 – 59 | D495 |
| Compressive Strength | 33 – 35 | D695 |
| Conditioning | 5 | D618 |
| Dielectric Strength | 48 – 51 | D149 |
| Dissipation Factor | 43 – 47 |
