标准摘要
[中文适用范围]： 本国际标准描述了使用自动分析仪采样和测定环境空气中二氧化硫（SO2）浓度的紫外荧光方法。 本标准适用于每立方米几微克至每立方米几毫克或以体积分数表示每立方米几微升至每立方米几毫升的二氧化硫质量浓度的测定。 [外文原描述]： ISO 10498:2004 describes an ultraviolet fluorescence method for sampling and determining sulfur dioxide (SO 2 ) concentrations in the ambient air using automatic analysers. ISO 10498:2004 is applicable to the determination of sulfur dioxide mass concentrations of a few micrograms per cubic metre to a few milligrams per cubic metre or, expressed in terms of volume fraction, from a few microlitres per cubic metre to a few millilitres per cubic metre.
