ASTM D409-97e2 聚氯乙烯（PVC）透层窗/滑动玻璃门的标准规范

1.1 This test method covers the determination of the relative grindability or ease of pulverization of coals in comparison with coals chosen as standards. A prepared and sized sample receives a definite amount of grinding energy in a miniature pulverizer, and the size consist of the pulverized product is determined by sieving. The resultant size consist is used to produce an index relative to the ease of grinding (Hardgrove Grindability Index (HGI)). 1.1.1 Some coals, such as some high volatile bituminous, subbituminous and lignite coals, can undergo physical change as the natural or seam moisture is released during handling and preparation. This change is often sufficient to alter the grindability characteristics that will be reported when tested in the laboratory, and could produce different indices dependent on the conditions of drying and the moisture level of the 1.18 mm by 600 [mu]m (No. 16 X No. 30) (See Test Method D4749.) materials used for the test. Therefore, the repeatability and reproducibility cited in this test method may not apply for these high volatile bituminous, subbituminous, and lignite coals. 1.2 The values stated in SI units are to be regarded as the standard.

ASTM D5263-93(2001) 碱萃取时烟煤中氧化过程相对等级测量的标准试验方法

This test method is a relative measure of the degree of oxidation present in coal. It does not determine the quantitative amount of oxidized coal present. It is only intended to serve as a guide to the supplier, buyer, and user for selecting coals for metallurgical use. Note 18212;The values shown in Table 1 are based on the transmittance obtained using the original procedure4 (wavelength at 520 nm, 17-mm light path, 2– to 3-min boiling time, dilution of the extract to 80 mL). At these conditions, coals that had transmittance values greater than 90 % were considered to be unoxidized, coals less than 80 % were considered to be oxidized, and coals between 80 and 90 % were considered suspect. As this procedure becomes accepted as the standard and more experimental data are gathered, modifications to these cutoff values are expected. Note that lower rank bituminous coals are more easily extracted than higher rank coal. TABLE 1 Guidelines for General Acceptance/Rejection Levels of Oxidized Coal Percent Transmittance at 520 nm, 17-mm Light Path Interpretation of Results >90 Coal is not oxidized. Suitable for metallurgical usage. 80 to 90Coal may be oxidized. If it is being used metallurgically, it should be monitored closely for further changes in oxidation. <80 Coal is oxidized.
