ASTM-B613 › Standard Guide for Preparing Specifications for Miniature Brushes of Composite Materials for Sliding Electric Contacts
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This guide defines the criteria for composition, properties, and other requirements for brushes containing a matrix of one or more conducting metallic elements or alloys and one or more lubricating lamellar solids.
1.2 The resulting specification is intended for use where the size (for example, 5 by 3 by 2 mm), shape, or other factors preclude the determination of properties on specimens of the bulk material from which individual brushes are made.
1.3 The requirements recommended herein have been found to be desirable for most brush material composites. Care must be taken in preparing a specification for a pre-existing material that imposition of one or more provisions herein does not alter the material or its performance.
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.
