Standard Test Methods for Glass-Bonded Mica Used as Electrical Insulation
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
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 | D150 and D2149 |
Heat Distortion Temperature | 24 – 29 | D648 |
Impact Resistance | 36 – 39 | D256 |
Modulus of Rupture | 30 – 32 | D790 and C674 |
Permittivity | 43 – 47 | D150 and D2149 |
Porosity | 13 – 16 | D116 |
Resistivity, Volume and Surface | 52 – 56 | D257 |
Rockwell Hardness | 10 – 12 | D785 |
Specific Gravity | 6 – 9 | D792 |
Specimens | 4 |
|
Tensile Strength | 40 – 42 | D638 and D651 |
Terminology | 3 | D1711 |
Thermal Conductivity | 17 – 19 | C177 and E1225 |
Thermal Expansion | 20 – 23 | E228 and E289 |
Thickness | 49 and 54 | D374 |
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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. See also Sections 45, 49, 54, and 58.
Significance and Use
6.1 This characteristic is useful for specification purposes and has utility as a quality control parameter.
