2002 年，欧洲标准化委员会 (CEN) 发布了文件《工作场所大气——空气颗粒浓度测量仪器性能评估》(EN 13205)，该文件描述了一个标准协议，通过该协议对广泛用于职业气溶胶暴露评估的个人气溶胶采样器进行测试和验证。它是经过十多年的讨论和涉及多个实验室的大量研究经验而产生的。然而，所描述的协议仍然带来重大的技术和经济挑战，尤其是因为它涉及大型专业风洞设施中的费力（因此成本高昂）程序。最近的研究已经确定了可以改进协议并使测试实验室更容易访问协议的许多领域，包括一套经过验证的气溶胶采样器缩放法则、更好地了解佩戴者钝体对采样器性能的影响减少以及快速采样器测试方法的新选项的可用性。考虑到这些，提出了一个虚拟的新协议供讨论。
In 2002 the Comité Européen Normalisation (CEN) published its document Workplace atmospheres—assessment of performance of instruments for measurement of airborne particle concentrations (EN 13205) that describes a standard protocol by which to carry out the testing and validation of personal aerosol samplers of the type widely used for occupational aerosol exposure assessment. It emerged from more than a decade of discussion and a large body of research experience involving several laboratories. The protocol that is described, however, still poses significant technical and economic challenges, not least because it involves laborious—and hence costly—procedures in large, specialized wind tunnel facilities. More recent research has identified a number of areas by which the protocol may be improved and made more accessible to testing laboratories, including a set of validated aerosol sampler scaling laws, a better understanding of the reduced role of the bluff body of the wearer on sampler performance, and the availability of new options for rapid sampler testing methods. Taking these into account, a dummy new protocol is offered for discussion.
