Organization: ASTM International
Publication Date: 1 November 2016
Status: active
Page Count: 7
ICS Code (Mica based materials): 29.035.50
significance And Use:

6.1 This characteristic is useful for specification purposes and has utility as a quality control parameter.

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.
