标准摘要
[中文适用范围]： 本文件规定了采用仪器法测定煤和焦炭中总碳、氢和氮的方法 [外文原描述]： This document specifies a method for the determination of total carbon, hydrogen and nitrogen in coal and coke by instrumental methods. NOTE This document has been validated for coal only, in accordance with the principles of ISO 5725-1. The suite of samples used in the interlaboratory study (ILS) to determine the precision data did not include coke and therefore there is insufficient data to state precision limits for coke.
英文名称Coal and coke — Determination of total carbon, hydrogen and nitrogen — Instrumental method
