标准范围

本文件对煤中微量元素测定方法的选择提供了指导和要求。具有环境意义的微量元素包括锑、砷、铍、硼、镉、氯、铬、钴、铜、氟、铅、锰、汞、钼、镍、硒、铊、钒和锌。放射性微量元素钍和铀可以添加到此列表中。本文件未规定用于测定单个微量元素的方法。对适当的认证标准物质（CRM）的分析对于确认所用方法的准确性至关重要（见ISO指南33）。

This document provides guidance and requirements on the selection of methods used for the determination of trace elements in coal. The trace elements of environmental interest include antimony, arsenic, beryllium, boron, cadmium, chlorine, chromium, cobalt, copper, fluorine, lead, manganese, mercury, molybdenum, nickel, selenium, thallium, vanadium and zinc. The radioactive trace elements thorium and uranium can be added to this list.This document does not prescribe the methods used for the determination of individual trace elements. The analysis of appropriate certified reference materials (CRMs) is essential to confirm the accuracy of any method used (see ISO Guide 33).
