Abstract This part of ISO 7404 specifies the method for deter- mining microscopically the maximum and random reflectance in oil of polished surfaces of the vitrinite component of coals. The method is applicable to ei- ther coals from single seams or coal blends covering the whole range of bituminous coal and anthracite. By itself, this method is unsuitable for determining the proportion of components in a blend, particularly when the components have dissimilar measurable vitrinite contents. The method necessitates the identification of vitrinite by the operator. Reflectance measurements on vitrinite obtained by interpreting the results of a com- puterized automated system of microscopic analysis are outside the scope of this part of ISO 7404.
