标准范围

本文件规定了使用采样器评估测量程序的要求，该采样器用于确定工作场所大气中存在的气载颗粒和蒸汽混合物形式的化学试剂。本文件中给出的程序仅提供空气中颗粒和蒸汽的总和结果。浓度以每单位体积的质量计算。注意事项空气中颗粒物和蒸汽混合物的物理特性见附件A、 可以多相存在的物质的实例是甲苯二异氰酸酯、二乙醇胺、乙二醇和磷酸三丁酯。本文件也适用于复杂混合物，如金属加工液或沥青烟气。本文件适用于在不同阶段进行取样和分析的采样器和使用这些采样器的测量程序。

This document specifies requirements for the evaluation of measuring procedures using samplers for the determination of a chemical agent present in the workplace atmosphere as a mixture of airborne particles and vapour.The procedures given in this document provide results only for the sum of airborne particles and vapour. The concentration is calculated in terms of mass per unit volume.NOTE      The physical behaviour of a mixture of airborne particles and vapour is described in Annex A. Examples of substances which can be present in multiple phases are toluene diisocyanate, diethanolamine, ethyleneglycol and tributylphosphate.This document can also be applied to complex mixtures, such as metal working fluids or bitumen fumes.This document is applicable to samplers and measuring procedures using these samplers in which sampling and analysis are carried out in separate stages.
