标准摘要
[中文适用范围]： 本文件规定了通过手动筛分（湿筛或干筛）对煤进行粒度分析的参考方法，所用试验筛的筛孔尺寸在90 mm至45 μm之间。采样指南见附录A。 本文件适用于所有煤。不适用于焦炭。 对于已研磨至大部分通过最小筛孔尺寸试验筛的粉煤，本文件的方法仅测定以百分比表示的筛上物质量分数。 [外文原描述]： This document specifies reference methods for the size analysis of coal by manual sieving (wet or dry), using test sieves of aperture sizes between 90 mm and 45 μm. A guide to sampling is given in Annex A. This document is applicable to all coals. It is not applicable to coke. In the case of pulverized coal which has been ground so that a high proportion passes through the test sieve of the smallest aperture size, the methods of this document determine only the mass fraction oversize expressed as a percent.
