Abstract

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.

Scope

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.

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 Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.
