Standard Test Methods for Sampling and Testing Untreated Mica Paper Used for Electrical Insulation
ASTM D1677-17
Organization:
ASTM - ASTM International
Year: 2024
Abstract: 7.1 Accurate determination of thickness is important for identification purposes. Thickness is related to weight and must be known in order to calculate apparent density and the dielectric strength. 7.2 Thickness variation affects the quality of roll winding and is useful in judging the uniformity of mica paper particularly with respect to dielectric breakdown voltage, impregnation time, and thickness of the end product.

| scope | 1.1 These test 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. 1.2 The 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/D374M Weight 11 D646 Weight Variability 29 – 31 ... 1.3 The values stated in inch-pound units are to be regarded as the standard. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This 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. | |
