This standard has been revised by ISO 7404-1:2016
Cancels and replaces the first edition (1984). Defines terms that are used in connection both with maceral and microlithotype analyses carried out in white light and with the determination of the reflectance of vitrinite. Applies to the terms used in examination of bituminous coal and anthracite only. Not concerned with the analysis of brown coal, sub-bituminous coal or lignite.
