Anthracite and bituminous coal granular samples should be prepared in accordance with ASTM D2797/D2797M-21a, a standard procedure that offers instructions for doing so. This procedure is used to make sure that coal samples are examined under a microscope consistently and accurately.
According to the standard, oriented coal blocks cannot be prepared using the preparation methods described in the practise. The standard focuses on granular samples because they are frequently used for microscopical investigation in studies and assessments of coal quality.
