ISO 11338-1:2003描述了测定固定来源（如铝冶炼厂、焦炭厂、垃圾焚烧炉、发电站以及工业和家用燃烧设备）烟气排放物中多环芳烃（PAHs）质量浓度的方法。 ISO 11338-1:2003描述了三种取样方法，在这里被视为等效值，并规定了有效多环芳烃取样的最低要求。三种取样方法分别为稀释法（A）、加热过滤器/冷凝器/吸附器法（B）和冷却探针/吸附器法（C）。这三种方法都基于代表性等速采样，因为多环芳烃通常与烟气中的颗粒物有关。 提供的信息有助于为所考虑的测量应用选择适当的采样方法。 ISO 11338-1:2003不适用于多环芳烃无组织排放的采样。 注:ISO 11338-2中描述了样品制备、清理和分析的方法，并打算与ISO 11338-1中描述的一种取样方法相结合，以完成整个测量程序。

ISO 11338-1:2003 describes methods for the determination of the mass concentration of polycyclic aromatic hydrocarbons (PAHs) in flue gas emissions from stationary sources such as aluminium smelters, coke works, waste incinerators, power stations, and industrial and domestic combustion appliances. ISO 11338-1:2003 describes three sampling methods, which are here regarded as of equivalent value, and specifies the minimum requirements for effective PAH sampling. The three sampling methods are the dilution method (A), the heated filter/condenser/adsorber method (B) and the cooled probe/adsorber method (C). All three methods are based on representative isokinetic sampling, as the PAHs are commonly associated with particles in flue gas. Information is provided to assist in the choice of the appropriate sampling method for the measurement application under consideration. ISO 11338-1:2003 is not applicable to the sampling of fugitive releases of PAHs. NOTE Methods for sample preparation, clean-up and analysis are described in ISO 11338-2 and are intended to be combined with one of the sampling methods described in ISO 11338-1 to complete the whole measurement procedure.
