本文件规定了在规定实验室条件下评估扩散取样器（见参考文献[1]）和使用这些取样器测定工作场所大气中气体和蒸汽的程序的性能要求和试验方法（见参考文献[2]）。 本文件适用于扩散取样器和使用这些取样器的测量程序，如ISO 16200-2和ISO 16017-2，其中采样和分析分为不同阶段进行。

This document specifies performance requirements and test methods under prescribed laboratory conditions for the evaluation of diffusive samplers (see Reference [1]) and of procedures using these samplers for the determination of gases and vapours in workplace atmospheres (see Reference [2]). This document is applicable to diffusive samplers and measuring procedures using these samplers, such as ISO 16200-2 and ISO 16017-2, in which sampling and analysis are carried out in separate stages.
