This standard covers terminology and test methods for those physical and chemical properties relevant to the material characterization of powdered graphite, generally less than 75 microns, used in the electrical industry. The test methods specified assume adherence to good laboratory...
Graphite, Graphene, and Their Polymer Nanocomposites presents a compilation of emerging research trends in graphene-based polymer nanocomposites (GPNC). International researchers from several disciplines share their expertise about graphene, its properties, and the behavior of...
This specification deals with compacted graphite iron castings. These materials shall be examined metallographically for the acceptance graphite formation. The acceptable graphite formation in the microstructure of the test coupon or casting lug shall contain 80% minimum...

This specification defines the criteria for the chemical composition and other requirements (including physical properties, microstructure, superficial hardness, and specific resistance ) for silver-graphite brushes for sliding electrical contacts. The percentage of silver, graphite,...
1.1 This guide covers procedures for the impregnation of graphite with molten salt under a consistent pressure and temperature. Such procedures are necessary if the user wishes to prepare graphite specimens for testing that represent material that has been exposed to a molten...
4.1 This test method provides a practical estimate of nonburnable residues in commercially available graphite materials. The ash values determined by this test method are of use in comparing the relative purity of various grades of graphite. To facilitate use, this test method...
1 Scope This material specification applies to grades of compacted graphite iron castings used in automotive and allied industries. Compacted graphite iron (CGI) is also known as vermicular graphite iron. This specification specifies mechanical properties from separately...
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...
This material specification applies to grades of compacted graphite iron castings used in automotive and allied industries. Compacted graphite iron (CGI) is also known as vermicular graphite iron. This specification specifies mechanical properties from test bars machined...
Humans first used carbon as chars from firewood in ritual paintings and primitive metallurgical processes. Natural forms of carbon have been known since antiquity, yet the knowledge of the carbon element in chemistry and its technical applications on a larger scale are a relatively recent...
This specification covers the requirements for the procurement of one type of ground Ceylon-type graphite.
This specification covers high-purity graphite disk and rod electrodes used in rotary disk electrode optical emission spectrometers for wear particle analysis through detection of metallic elements in oils and other fluids.
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. The values stated in inch-pound units are to be regarded as standard. No other units of measurement are...
4.1 Nuclear grade graphite is a composite material made from petroleum or a coal-tar-based coke and a pitch binder. Manufacturing graphite is an iterative process of baking and pitch impregnation of a formed billet prior to final graphitization, which occurs at...
1.1 This guide covers best practice for properties measurements on small (nonstandard) graphite specimens and requirements for representing properties of the bulk material. This guide is aimed specifically at measurements required on graphites, where there may be constraints on...
