欧洲标准的这一部分规定了用于确定环境空气中气体和蒸气浓度的扩散取样器的一般性能要求。这种要求适用于所有扩散取样器，不论速率控制过程的物理性质如何，而不考虑吸附过程的性质和分析测定。本标准适用于测量程序的所有阶段，包括样品的部署，运输和储存

This part of the European Standard specifies general performance requirements for diffusive samplers used for the determination of the concentration of gases and vapours in ambient air. Such requirements apply to all diffusive samplers, irrespective of the physical nature of the rate controlling process and irrespective of the nature of the sorption process and the analytical determination. This standard applies to all stages of the measuring procedure, including deployment, transportation and storage of the sample where appropriate.
