1.1 These test methods cover the preparation and tensile testing of resin-impregnated and consolidated test specimens made from continuous filament carbon and graphite yarns, rovings, and tows to determine their tensile properties. 1.2 These test methods also cover the determination of the...
4.1 The iodine adsorption number is useful in characterizing carbon blacks. It is related to the surface area of carbon blacks and is generally in agreement with nitrogen surface area. The presence of volatiles, surface porosity, or extractables will influence the iodine adsorption...
This guide covers a group of requirements for carbon and alloy steel bars under each of the following specifications: hot-rolled carbon steel bars, cold-finished carbon steel bars, hot-rolled alloy steel bars, and cold-finished alloy steel bars. Heat and product analysis shall...
1.1 This classification covers fiber reinforced carbon-carbon (C-C) composite structures (flat plates, rectangular bars, round rods, and tubes) manufactured specifically for structural components. The carbon-carbon composites consist of carbon/graphite fibers...
1.1 This test method determines the in-plane permeability of composite prepreg (pre-impregnated) materials as a measure of level of impregnation. Permissible prepreg materials include those reinforced with carbon, glass, aramid, thermoplastic and other fibers impregnated with a...
1.1 This specification2 covers a group of common requirements that, unless otherwise specified in the individual product specification, shall apply to steel forgings under any of the following specifications issued by ASTM: ASTM Designation Title A266/A266M Carbon Steel Forgings for Pressure...
3.1 This practice is intended to ensure that SRBs are produced and evaluated by a standard procedure. 3.2 This practice is to be used to establish the average physicochemical properties of a set of carbon blacks to be used as SRBs. 3.3 The carbon black grades to be used as SRBs should...
4.1 The moisture content of activated carbon is often required to define and express its properties in relation to the net weight of the carbon. 4.2 The moisture content of activated carbon packed in typical shipping containers will usually increase during transportation and...
1.1 This test method provides a thermogravimetric (TGA) technique to determine the amounts of organic residue, overall carbon content, and ash content in recovered carbon black (rCB). 1.2 This test method uses previously calibrated, manual, or computer-assisted TGA instrumentation. 1...
5.1 This procedure is intended to determine the total extractable materials in rubber. It will give the combined amount of rosin and fatty acids, soaps, extender oils, defoamer tars, antioxidants, and other uncombined organic constituents that are extractable in the solvent used. The rubber...
