标准摘要
[中文适用范围]： 本文件规定了在规定的实验室条件下评估与空气采样泵一起使用的泵送采样器的性能要求和测试方法，以及使用这些采样器测定工作场所大气中的气体和蒸汽的程序。 本文件满足了方法开发商和/或制造商的要求。 注 1：就本文件而言，制造商可以是任何商业或非商业实体。 注 2：对于在工作场所大气中以蒸气和空气颗粒混合物形式出现的半挥发性化合物的取样，请参见 EN 13936。 本文件适用于泵式取样器和使用这些取样器的测量程序，其中取样和分析是在单独的阶段。 本文件不适用于： ——用于直接测定浓度的泵式采样器，例如染色长度检测管； ——依靠吸附到液体中并随后对溶液进行分析的采样器（起泡器）。 [外文原描述]： This document specifies performance requirements and test methods under prescribed laboratory conditions for the evaluation of pumped samplers used in conjunction with an air sampling pump and of procedures using these samplers for the determination of gases and vapours in workplace atmospheres. This document addresses requirements for method developers and/or manufacturers. NOTE 1 For the purposes of this document, a manufacturer can be any commercial or non-commercial entity. NOTE 2 For the sampling of semi-volatile compounds which can appear as a mixture of vapours and airborne particles in workplace atmospheres see EN 13936. This document is applicable to pumped samplers and measuring procedures using these samplers in which sampling and analysis are carried out in separate stages. This document is not applicable to: — pumped samplers which are used for the direct determination of concentrations, for example, length-of-stain detector tubes; — samplers which rely on sorption into a liquid, and subsequent analysis of the solution (bubblers).
