Annotation

This guide defines the criteria for composition, properties, and other requirements for miniature brushes of composite materials containing a matrix of one or more conducting metallic elements or alloys and one or more lubricating lamellar solids intended for sliding electric contacts. Each constituent of the material should be listed individually by weight percent including tolerances using any analytical technique while the apparent density for the material should be defined using the measurement and weight method. The resistivity; Rockwell superficial hardness, transverse strength, and shear strength; and microstructural properties such as cracks and defects should also be defined and should conform to the required electrical, mechanical, and structural properties of the brush materials.
