ISO 23210:2009规定了使用两级冲击器测定固定排放源处PM10和PM2.5质量浓度的标准参考方法。该测量方法特别适用于在标准条件下（273 K，1 013 hPa，干气）以半小时平均值测量低于40 mg/m3的质量浓度。这是一种可接受的方法，用于测量不同装置（如水泥和钢铁生产厂）以及燃烧过程中的烟气。 ISO 23210:2009不适用于饱和水蒸气的烟气取样。 ISO 23210:2009不适用于大多数颗粒物可能超过PM10的情况，例如，在原料气或电厂运行故障的情况下。 ISO 23210:2009不能用于测定粉尘的总质量浓度。 ISO 23210:2009描述了圆形喷嘴冲击器的设计、使用和理论。它不排除其他类型的冲击器，前提是这些系统在独立测试实验室进行的冲击器验证中满足ISO 23210:2009中规定的性能标准。

ISO 23210:2009 specifies a standard reference method for the determination of PM10 and PM2,5 mass concentrations at stationary emission sources by use of two-stage impactors. The measurement method is especially suitable for measurements of mass concentrations below 40 mg/m3 as half-hourly averages in standard conditions (273 K, 1 013 hPa, dry gas). It is an acceptable method for the measurement in the flue gas of different installations, such as cement and steel production plants, as well as combustion processes. ISO 23210:2009 is not applicable to the sampling of flue gases that are saturated with water vapour. ISO 23210:2009 is not applicable where the majority of the particles are likely to exceed PM10, for example, in the case of raw gases or plant operating failures. ISO 23210:2009 cannot be used for the determination of the total mass concentration of dust. ISO 23210:2009 describes the design, use and theory of round-nozzle impactors. It does not exclude other types of impactors, provided these systems meet the performance criteria specified in ISO 23210:2009 in a validation of the impactor performed by an independent testing laboratory.
