标准摘要
[中文适用范围]： 本文件规定了在浸油的抛光表面上，通过显微镜测定煤中惰质组反射率的方法。这些方法适用于来自单一煤层或煤混合物的煤，覆盖所有低阶、中阶和高阶煤的范围。惰质组反射率的测定可用于表征混合物中的成分。可以采取措施，对混合物中每个成分的惰质组百分比进行校正，或确定混合物中各成分的比例，尤其是在各成分惰质组含量差异较大的情况下。本方法要求分析人员对惰质组进行识别。通过自动系统解释结果而获得的惰质组反射率测定值，不在本文件的适用范围内。 [外文原描述]： This document specifies the methods for determining the reflectance of vitrinite of coals microscopically on polished surfaces, immersed in oil. The methods are applicable to coals from single seams or coal blends covering the whole range of low-, medium- and high-rank coal. Vitrinite reflectance measurements can be used to characterize the components within blends. Measures can be taken to correct for the vitrinite percentage within each of the components of the blend or to determine the proportion of components in a blend, particularly when the components have dissimilar vitrinite contents. This method necessitates the identification of vitrinite by the analyst. Reflectance measurements on vitrinite, obtained by interpreting the results from an automated system, are outside the scope of this document.
