<p>This document describes a simple classification system for coals providing</p>
<p>— guidance on the selection of the appropriate ISO standard procedures for the analyses and testing of coals,</p>
<p>— international comparison of coals in terms of some key characteristics,</p>
<p>— descriptive categorization of coals.</p>
<p>The system is applicable to coals of all ranks, but care is required in relation to the classification of some types of coal.</p>
<p>The system can be applied to a wide range of representative coal samples, provided their exact nature is stated. Such samples include bore-core seam sections and composite samples, raw (as-mined) coal, washed coal, blends of coals of similar rank and selected, specified size fractions.</p>
<p>The system provides a broad framework within which coals can be assessed. The selection of coals for a specific use requires detailed information that enables the likely performance of a coal in a particular application to be anticipated. The wide-ranging list of ISO analyses and test procedures for coals serve this purpose. The selection of the appropriate procedures to be used in assessing a coal depends on the intended use.</p>
