CONTAINED IN VOL. 10.01, 2017 Defines the evaluation of the characteristics of glass-bonded, natural, or synthetic mica materials intended for use as electrical insulation.

1.1These test methods cover the evaluation of the characteristics of glass-bonded, natural, or synthetic mica materials intended for use as electrical insulation.

1.2Glass 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.)

1.3The test methods appear in the following sections:

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

1.4The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5This 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.
