CONTAINED IN VOL. 10.01, 2017 Describes procedures for sampling and testing untreated mica paper to be used as an electrical insulator or as a constituent of a composite material used for electrical insulating purposes.

1.1These methods cover procedures for sampling and testing untreated mica paper to be used as an electrical insulator or as a constituent of a composite material used for electrical insulating purposes.

1.2The procedures2 appear in the following order:

		ASTM
		Method
Procedures	Sections	References
Apparent Density	12	...
Aqueous Extract Conductivity	32 and 33	D202
Conditioning	4	D685
Dielectric Strength	16 – 19	D149
Impregnation Time	20 – 24	D202
Moisture Content	26 – 28	D644
Roll Quality	25	...
Sampling	3	...
Tensile Strength	13 – 15	D828
Thickness	6 – 10	D374
Weight	11	D646
Weight Variability	29 – 31	...

1.3The values stated in inch-pound units are to be regarded as the standard.

1.4This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
