标准摘要
[中文适用范围]: 本文件规定了一种方法,用于测定工作场所空气中氯化氢 (HCl) 气体和盐酸雾、溴化氢 (HBr) 蒸气和氢溴酸雾以及硝酸 (HNO3) 蒸气和雾的时间加权平均质量浓度,方法是通过碱浸渍石英纤维过滤器收集并通过离子色谱法进行分析。对于雾气采样,该方法适用于 ISO 7708 中定义的可吸入空气颗粒物部分的个人采样和静态(区域)采样。 [外文原描述]: This document specifies a method for the determination of the time-weighted average mass concentration of hydrogen chloride (HCl) gas and hydrochloric acid mist, hydrogen bromide (HBr) vapour and hydrobromic acid mist and nitric acid (HNO 3 ) vapour and mist in workplace air by collection on an alkali-impregnated quartz fibre filter and analysis by ion chromatography. For mist sampling, this method is applicable to the personal sampling of the inhalable fraction of airborne particles as defined in ISO 7708 and to static (area) sampling.
