ASTM D5142-2004 使用仪器测量法进行煤和焦炭分析样品近似值分析的标准试验方法
简介:Moisture, as determined by the instrumental test method, is used for calculating other analytical results to a moisture-free basis using procedures in Practice D 3180. Moisture percent determined by this test method may be used in conjunction with the air-dry moisture loss determined in Method D 2013 and Test Method D 3302 to determine total moisture in coal. Total moisture is used for calculating other analytical results to an as-received basis using Practice D 3180. Ash yield, as determined by this test method, is the residue remaining after burning the coal and coke samples. Volatile matter yield, when determined as herein described, may be used to (1) establish the rank of coals, (2) indicate coke yield on carbonization, (3) provide the basis for purchasing and selling, or (4) establish burning characteristics. Fixed carbon is a calculated value. It is the difference between 100 and the sum of the percent moisture, ash, and volatile matter. All percents shall be on the moisture reference base. Moisture, ash, volatile matter, and fixed carbon percents constitute the proximate analysis of coal and coke. Note 18212;The ash obtained differs in composition and amount from the mineral constituents present in the original coal. Incineration causes an expulsion of all water, the loss of carbon dioxide from carbonates, the conversion of iron pyrite into iron oxides and sulfur oxides, and other chemical reactions. Ash yield, as determined by this test method, can differ from the amount of ash produced in furnace operations or other combustion systems because incineration conditions influence the chemistry and amount of ash.1.1 These instrumental test methods cover the determination of moisture, volatile matter, and ash, and the calculation of fixed carbon in the analysis of coal and coke samples prepared in accordance with Method D 2013 and Practice D 346. Results obtained through the use of the instrumental tests have been shown to differ from those obtained with Test Methods D 3173, D 3174, and D 3175 on some coals and cokes. Where a relative bias between the instrumental methods and Test Methods D 3173, D 3174, and D 3175 for proximate analysis of coal and coke are shown to exist, the instrumental results shall be corrected or the instrument calibrated using samples of known proximate analysis. Test Methods D 3173, D 3174, and D 3175 shall be considered the referee test methods. The instrumental test methods are not applicable to thermogravimetric analyzers using microgram size samples.1.2 The moisture value determined is used for calculating other analytical results to a dry basis. When used in conjunction with the air dry loss moisture, as determined in accordance with Method D 2013, Test Method D 3302, or Practice D 346, the calculated total moisture can be used to convert dry basis analytical results to the as-received basis.1.3 The result of the ash determinations can be applied in the ultimate analysis, Practice D 3176.1.4 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.

ASTM D5142-2009 使用仪器测量法进行煤和焦炭分析样品近似值分析的标准试验方法
简介:Moisture, as determined by this instrumental test method, is used for calculating other analytical results to a dry basis using procedures in Practice D 3180. Moisture as determined by this test method, may be used in conjunction with the air-dry moisture loss determined by Test Method D 3302 to determine total moisture in coal. Total moisture is used for calculating other analytical results to an as-received basis using Practice D 3180. Ash yield, as determined by this test method, is the residue remaining after burning the coal and coke samples. See Note 1. Note 18212;The ash obtained differs in composition and amount from the mineral constituents present in the original coal. Combustion causes an expulsion of all water, the loss of carbon dioxide from carbonates, the conversion of iron pyrite into iron oxides and sulfur oxides, and other chemical reactions. Ash yield, as determined by this test method, can differ from the amount of ash produced in furnace operations or other combustion systems because combustion conditions influence the chemistry and amount of ash. Ash yield, as determined by this test method is used, (1) as a principal parameter to evaluate sampling procedures and coal cleaning processes, (2) in the ultimate analysis calculation of oxygen by difference using Practice D 3176, (3) in calculations including material balance, reactivity and yields of products relevant to coal conversion processes such as gasification and liquefaction. Volatile matter yield, when determined as herein described, may be used to (1) establish the rank of coals, (2) indicate coke yield on carbonization, (3) provide the basis for purchasing and selling, or (4) establish burning characteristics. 5.6 Fixed carbon is a calculated value. It is the difference between 100 and the sum of the percent moisture, ash, and volatile matter. All percents shall be on the same moisture reference base. 5.7 Moisture, ash, volatile matter, and fixed carbon percents constitute the proximate analysis of coal and coke. 5.8 Moisture, ash, and volatile matter are three of the principal parameters used for assessing the quality of coal.1.1 These instrumental test methods cover the determination of moisture, volatile matter, and ash, and the calculation of fixed carbon in the analysis of coal and coke samples prepared in accordance with Method D 2013 and Practice D 346. Results obtained through the use of the instrumental tests have been shown to differ from those obtained with Test Methods D 3173, D 3174, and D 3175 on some coals and cokes.

Test Methods D 3173, D 3174, and D 3175 shall be considered the referee test methods. The instrumental test methods are not applicable to thermogravimetric analyzers using microgram size samples. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard......

ISO 6145-5-2001 气体分析 用动态容量法制备标定用混合气体 第5部分:毛细管校准仪器
简介:This part of ISO 6145 specifies a technique for the continuous production of calibration gas mixtures from pure gases or gas mixtures using capillary devices in single or multiple combinations (gas dividers).Single capillary systems can be used to provide gas mixtures where the minor component is in the range of volume fractions from 10 to 0,5.The relative repeatability of this technique is approximately 2 %. This application is used in industrial gas mixing panels for the production of specific gas atmospheres.Gas dividers can be used to divide gas mixtures prepared from gases or gas mixtures into controlled proportions by volume. These devices are capable of dilutions in the range of volume fractions from 0,1 to 0,9 of the primary gas with a relative repeatability of better than 0,5 %.Traceability of the gas mixtures produced by a gas divider can be achieved by comparison of a mixture at the higher and lower end of the range with gas mixtures related to national or international gas standards. An example is given in annex A.
