This Standard sets out methods for the microscopical determination of the maximum and random reflectance in oil of polished surfaces of coal macerals. The methods are applicable to coal covering the whole rank range from brown coal to anthracite, and may be used for the following purposes:(a) Exploration and preliminary assessment of coal quality.(b) Technological purposes and quality control.(c) Determination of thermal maturation index for petroleum exploration.NOTES:1. Reflectance measurements on coal macerals, obtained by interpreting the results of a computerized automated system of microscopic analysis, are outside the scope of this Standard.2. If measurements are made in a medium other than oil, e.g. air, this should be stated.
