The properties included in this standard are those required to control the visual quality, usable area, thickness, hardness, and stiffness.1.1 This classification covers the determination of commercially available natural muscovite block mica and is intended to be independent of the basic color of the mica or its source. 1.2 Muscovite mica is characterized by having an optical axial angle between 50 and 75° (see Appendix X1); and has a weight loss when heated for 5 min at 600°C not exceeding 0.2 % (based on the weight after drying at 120°C). 1.3 The visual system of classifying the quality of natural muscovite mica covered by this specification is based upon relative amounts of visible foreign inclusions such as air bubbles, stains, and spots in combination with relative amounts and types of waviness, as well as other physical properties. In this system, a perfectly clear, transparent, flat specimen of mica is the visual standard of perfection. Increasing amounts of visual defects lower the visual quality, and a total of 13 levels of visual quality are covered by this standard. This method of classification, generally known as the Bengal India System, is purely qualitative and is entirely dependent on personal opinion and judgment. 1.4 The standards for visual quality classification that are covered in this classification are the best commercially available concept of the various qualities and their relative positions. Variations in the methods of using and applying these standards from those herein defined may be specified by the purchaser, or defined by agreement between the supplier and the purchaser. 1.5 Standard size classifications are defined, based upon available usable rectangular areas and the minimum dimensions of the rectangles that the pieces will yield. Precautions to be taken in making thickness measurements are also described. 1.6 This standard covers the following two definite forms of commercial preparation: 1.6.1 Form 18212;Full-trimmed natural block mica, 0.007 in. (0.178 mm) minimum thickness. 1.6.2 Form 28212;Partially-trimmed natural block mica, 0.007 in. minimum thickness. 1.7 The basic color of mica, such as white, ruby, light green, dark green, brownish green, and rum, as well as other colors, and the method of controlling the color and other problems associated with the basic color, are not a part of this classification. 1.8 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.9 Section 5 is technically identical to procedures specified in ISO 67-1981. 1.10 Section 6 differs somewhat in procedure from ISO 5972-1978, but data obtained by either should be identical. 1.11 Section 7 is technically identical to procedures specified in ISO 2185-1972.

1.1 This specification covers the determination of muscovite mica splittings of standard commercial grades and specifies the maximum allowable physical defects for each grade. It is applicable to commercially available natural muscovite mica splittings regardless of the basic color of the mica or its source.1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.1.3 This standard is very similar to ISO 6386. It is expected that materials would be classified identically using the criteria of either standard. The grades shown under "ASTM Grade No." in Table 1 and Table 2 are shown under "Old Grade No." in ISO 6386.

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: ASTM Method Section Method Reference Arc Resistance 11 D 495 Compressive Strength 19 and 20 D 695 Conditioning 4 D 618 Dielectric Constant and 6 D 150 Dissipation Factor Dielectric Strength 7 and 8 D 149 Heat Distortion 32 to 35 D 648 Impact Resistance 21 to 23 D 256 Modulus of Rupture 12 to 14 C 674 Porosity 24 D 116 Resistivity 9 and 10 D 257 Rockwell Hardness 28 D 785 Specific Gravity 29 and 30 D 792 Tensile Strength 15 to 18 D 651, D 638 Test Specimens 3 ... Thermal Conductivity 31 C 408, C 177 Thermal Expansion 25 to 27 Interferometric Method 26 C 539 Dilatometer Method 27 C 372 1.4 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.
