标准摘要
[中文适用范围]： 本国际标准规定了使用哈德格罗夫试验机测定硬煤可磨性指数的方法。它还规定了校准试验机和制备标准参考煤样的程序。注：在本国际标准中，“硬煤”一词用于指示煤化序列中的成熟度或等级，与煤的物理性质无关。 [外文原描述]： ISO 5074:2015 specifies the method for determining the grindability index of hard coal using the Hardgrove machine. It also specifies the procedure for calibrating the test machine and for preparing the standard reference coal samples. NOTE In this International Standard, the term "hard coal" is used as an indication of maturity or rank in the coalification sequence and is not related to the physical properties of the coal.
