标准摘要
[中文适用范围]: 本国际标准规定了连续分析和记录环境空气中一氧化碳(CO)含量的非色散红外光谱测定方法。 该方法适用于测定 0.6 mg/m3(0.5 ppm 体积分数)至 115 mg/m3(100 ppm 体积分数)的一氧化碳浓度。 该方法的检测下限为空气中约 0.06 mg/m3(0.05 ppm 体积分数)的一氧化碳。 [外文原描述]: This International Standard specifies a non-dispersive infrared spectrometry method for the continuous analysis and recording of the carbon monoxide (CO) content of the ambient air. The method is applicable to the determination of carbon monoxide concentrations from 0,6 mg/m3 (0,5 ppm volume fraction) to 115 mg/m3 (100 ppm volume fraction). The method has a lower limit of detection of about 0,06 mg/m3 (0,05 ppm volume fraction) carbon monoxide in air.
