ISO 10498:2004描述了一种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。 ISO 10498:2004适用于测定每立方米几微克至每立方米几毫克或以体积分数表示的每立方米几微升至每立方米几毫升的二氧化硫质量浓度。

ISO 10498:2004 describes an ultraviolet fluorescence method for sampling and determining sulfur dioxide (SO₂) 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.
