标准摘要
[中文适用范围]： 本标准规定了从管道和烟囱排放到大气的烟气中一氧化二氮（N2O）含量的采样、样品调节和测定方法。 它规定了非色散红外（NDIR）分析技术，包括采样系统和样气调节系统。 本国际标准是对永久安装在烟囱上的自动监测系统进行定期监测和校准、调整或控制的参考方法。 该参考方法已在污水污泥焚烧炉上成功测试，烟气中 N2O 浓度高达约 200 mg/m3。 [外文原描述]： ISO 21258:2010 specifies a method for sampling, sample conditioning and determination of dinitrogen monoxide (N 2 O) content in the flue gas emitted from ducts and stacks to atmosphere. It sets out the non-dispersive infrared (NDIR) analytical technique, including the sampling system and sample gas conditioning system. ISO 21258:2010 is a reference method for periodic monitoring and for calibration, adjustment or control of automatic monitoring systems permanently installed on a stack. This reference method has been successfully tested on a sewage sludge incinerator where the N 2 O concentration in the flue gas was up to about 200 mg/m 3 .
