Standard Specification for 80¿% Silver-20¿% Graphite Sliding Contact Material
This specification defines the criteria for composition and other requirements for sliding contact materials or brushes with a nominal composition by weight of 20% silver and 80% graphite. Materials shall adhere to specified requirements for chemical composition, density, shear strength, and microstructure. They shall also conform to typical values of Rockwell superficial hardness and specific resistance.
1.1 This specification defines the criteria for composition and other requirements for brushes with a nominal silver content of 80 %, by weight, with the balance being substantially graphite.
1.2 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 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 become familiar will all hazards including those identified in the appropriate Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use.
1.4 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.
