ISO 18144:2003规定了可吸入悬浮颗粒物（RSP）的取样和测定方法，以及可归因于环境烟草烟雾（ETS）的RSP分数的估算方法。本方法适用于个人和区域采样。该方法与重量分析RSP、紫外线颗粒物（UVPM）和荧光颗粒物（FPM）的测定兼容，也可用于估算ETS对RSP的贡献。

ISO 18144:2003 specifies a method for the sampling and determination of respirable suspended particles (RSP) and for the estimation of the RSP fraction attributable to environmental tobacco smoke (ETS). This method is applicable to personal and area sampling. This method is compatible with the determinations of gravimetric RSP, ultraviolet particulate matter (UVPM) and fluorescent particulate matter (FPM), which are also used to estimate the contribution of ETS to RSP.
