标准范围

ISO 11760:2005描述了一个简单的煤分类系统，为分析和测试、一些关键特性的国际比较和煤的描述性分类选择合适的ISO标准程序提供了指导。该系统适用于所有等级的煤炭，但在某些类型煤炭的分类方面需要谨慎。它也适用于范围广泛的代表性煤样，前提是说明了它们的确切性质。此类样品包括钻孔岩芯煤层剖面和复合样品、原煤（已开采）煤、洗煤、相似煤级和选定的指定粒度的混合煤。

ISO 11760:2005 describes a simple classification system for coals providing guidance on the selection of the appropriate ISO standard procedures for the analyses and testing, international comparison in terms of some key characteristics and descriptive categorization of coals. The system is applicable to coals of all ranks, but care is required in relation to the classification of some types of coal. It is also applicable 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.
