ASTM C714-2017 采用热脉冲法测定碳和石墨热扩散性的标准试验方法
简介:5.1x00a0;Thermal diffusivity is an important property required for such purposes as design applications under transient heat flow conditions, determination of safe operating temperature, process control, and quality assurance. 5.2x00a0;The flash method is used to measure values of thermal diffusivity (x03b1;) of a wide range of solid materials. It is particularly advantageous because of the simple specimen geometry, small specimen size requirements, rapidity of measurement, and ease of handling materials having a wide range of thermal diffusivity values over a large temperature range with a single apparatus. The short measurement times involved reduce the chances of contamination and change of specimen properties due to exposure to high temperature environments. 5.3x00a0;Thermal diffusivity results in many cases can be combined with values for specific heat (Cp) and density (x03c1;) to derive thermal conductivity (x03bb;) from the relation x03bb; = x03b1;Cpx03c1;. For guidance on converting thermal diffusivity to thermal conductivity, refer to Practice C781. 5.4x00a0;This test method can be used to characterize graphite for design purposes. 5.5x00a0;Test Method E1461 is a more detailed form of this test method and has applicability to much wider ranges of materials, applications, and temperatures. 1.1x00a0;This test method covers the determination of the thermal diffusivity of carbons and graphite at temperatures up to 5008201;x00b0;C. It requires only a small easily fabricated specimen. Thermal diffusivity values in the range from 0.048201;cm2/s to 2.08201;cm2/s are readily measurable by this test method; however, for the reason outlined in Section 7, for materials outside this range this test method may require modification. 1.2x00a0;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. 1.3x00a0;This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D5341/D5341M-2017 测量焦炭活性指数(CRI)和反应后的焦碳强度(CSR)的标准试验方法
简介:4.1x00a0;When coke lumps descend in the blast furnace, they are subjected to reaction with countercurrent CO2 and to abrasion as they rub together and against the walls of the furnace. These concurrent processes physically weaken and chemically react with the coke lumps, producing an excess of fines that can decrease burden permeability and result in increased coke rates and lost hot metal production. This test method is designed to measure indirectly this behavior of coke in the blast furnace. 1.1x00a0;This test method, patterned after the Nippon Steel test procedure, describes the equipment and techniques used for determining lump coke reactivity in carbon dioxide (CO2) gas at elevated temperatures and its strength after reaction in CO2 gas by tumbling in a cylindrical chamber referred to as an I-tester. 1.2x00a0;The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.3x00a0;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. 1.4x00a0;This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

简介:5.1x00a0;The combustible carbon content of solid residues is used to calculate efficiency of fuel combustion in boiler furnaces and similar combustors. 5.2x00a0;Combustible carbon values are also used to determine the residual fuel value of incompletely combusted/reacted coal and coke in other reactors that consume carbonaceous fuels (examples include fluidized bed furnaces and liquefaction, gasification and pyrolysis reactors). 5.3x00a0;The combustible carbon content of flyash is an important parameter in the use of flyash as a cement additive. 1.1x00a0;This test method covers the determination of total, combustible, and carbonate carbon remaining in the solid byproducts of combustion from boiler furnaces and similar reactors, including ash, flyash, char, slag, and similar materials. 1.2x00a0;This test method is intended for the use of industry to determine the performance of boiler furnaces and similar combustion reactors and aid in determining the quality of the solid residue from combustion. 1.3x00a0;This test method comprises the use of any of several methods to determine total carbon content combined with any of several methods to determine carbonate carbon, and the calculation, by difference, of the combustible carbon remaining in a sample. 1.4x00a0;Alternatively, this test method applies to the determination of total carbon remaining in a material after acidification with strong acid to evolve carbonate carbon. In this case, the combustible carbon is the total carbon measured in the sample after acidification. 1.5x00a0;The values stated in SI units are to be regarded as standard.

ASTM D6866-2016 采用放射性碳分析测定固体, 液体和气体样品中生物基含量的标准试验方法
简介:4.1x00a0;This testing method provides accurate biobased/biogenic carbon content results to materials whose carbon source was directly in equilibrium with CO2 in the atmosphere at the time of cessation of respiration or metabolism, such as the harvesting of a crop or grass living its natural life in a field. Special considerations are needed to apply the testing method to materials originating from within artificial environments. Application of these testing methods to materials derived from CO2 uptake within artificial environments is beyond the present scope of this standard. 4.2x00a0;Method B utilizes AMS along with Isotope Ratio Mass Spectrometry (IRMS) techniques to quantify the biobased content of a given product. Instrumental error can be within 0.1-0.5 % (1 relative standard deviation (RSD)), but controlled studies identify an inter-laboratory total uncertainty up to x00b1;38201;% (absolute). This error is exclusive of indeterminate sources of error in the origin of the biobased content (see Section 22 on precision and bias). 4.3x00a0;Method C uses LSC techniques to quantify the biobased content of a product using sample carbon that has been converted to benzene. This test method determines the biobased content of a sample with a maximum total error of x00b1;38201;% (absolute), as does Method B. 4.4x00a0;The test methods described here directly discriminate between product carbon resulting from contemporary carbon input and that derived from fossil-based input. A measurement of a productx2019;s8201;14C/12C or 14C/13C content is determined relative to a carbon based modern reference material accepted by the radiocarbon dating community such as NIST Standard Reference Material (SRM) 4990C, (referred to as OXII or HOxII). It is compositionally related directly to the original oxalic acid radiocarbon standard SRM 4990B (referred to as OXI or HOxI), and is denoted in terms of fM, that is, the samplex2019;s fraction of modern carbon. (See Terminology, Section 3.) 4.5x00a0;Reference standards, available to all laboratories practicing these test methods, must be used properly in order that traceability to the primary carbon isotope standards are established, and that stated uncertainties are valid. The primary standards are SRM 4990C (oxalic acid) for8201;14C and RM 8544 (NBS 19 calcite) for8201;13C. These materials are available for distribution in North America from the National Institute of Standards and Technology (NIST), and outside North America from the International Atomic Energy Agency (IAEA), Vienna, Austria. 4.6x00a0;Acceptable SI unit deviations (tolerance) for the practice of these test methods is x00b1;58201;% from the stated instructions unless otherwise noted. 1.1x00a0;This standard is a test method that teaches how to experimentally measure biobased carbon content of solids, liquids, and gaseous samples using radiocarbon analysis. These test methods do not address environmental impact, product performance and functionality, determination of geographical origin, or assignment of required amounts......

简介:5.1x00a0;Determining the type and amount of hydrocarbon impurities remaining from the manufacture of toluene, mixed xylenes, p-xylene, o-xylene, ethylbenzene, benzene, and styrene used as chemical intermediates and solvents is often required. This test method is suitable for setting specifications and for use as an internal quality control tool where these products are produced or are used. Typical impurities are: alkanes containing 1 to 10 carbons atoms, benzene, toluene, ethylbenzene (EB), xylenes, and aromatic hydrocarbons containing nine carbon atoms or more. 5.2x00a0;This method may not detect all components and there may be unknown components that would be assigned inappropriate correction factors and thus, the results may not be absolute. 1.1x00a0;This test method covers the determination of total nonaromatic hydrocarbons and monocyclic aromatic hydrocarbons in benzene, toluene, ethylbenzene, p-xylene, o-xylene, styrene and mixed xylenes by gas chromatography. The purity of benzene, toluene, ethylbenzene, p-xylene, o-xylene, styrene and mixed xylenes is also calculated. Similar test methods, using the internal standard calibration technique and the external standard calibration technique, are Test Methods D2360, D3797, D4492, D5060, D5135, D5917, and D6563 respectively. 1.2x00a0;The limit of detection (LOD) is 0.0002 wt % and limit of quantitation (LOQ) is 0.0006 wt % for impurities in toluene, mixed xylenes, p-xylene, o-xylene, ethylbenzene, benzene, and styrene. 1.3x00a0;In determining the conformance of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E29. 1.4x00a0;The values stated in SI units are to be regarded as standard.
