标准摘要
[中文适用范围]： 本国际标准规定了使用两级撞击器测定固定排放源 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标准条件（273 K、1 013 hPa、干燥气体）下半小时平均值低于 40 mg/m3 的质量浓度测量。 对于水泥和钢铁生产厂以及燃烧过程等不同装置的烟气测量来说，这是一种可接受的方法。 本标准不适用于饱和水蒸气的烟气取样。 本国际标准不适用于大多数颗粒物可能超过 PM10 的情况，例如未净化气体或工厂运行故障的情况。 注 1：在标准条件（273 K，1 013 hPa，干燥气体）下每半小时测量高于 40 mg/m3 的颗粒物浓度，可能导致收集板和备用过滤器过载，也可能导致更短的采样时间。 注 2：收集板和备用过滤器可用于进一步的化学分析。 本标准不能用于粉尘总质量浓度的测定。 注 3：出于数据评估的目的，与 PM10 和 PM2,5 测量并行地进行总颗粒物测量可能会很有用。 本国际标准描述了圆喷嘴冲击器的设计、使用和原理。 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执行的冲击器验证中满足本国际标准中规定的性能标准。 [外文原描述]： 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.
