标准范围

ISO 20846:2011规定了一种紫外(UV)荧光测试方法，用于测定含有高达3.7%(m/m)氧的车用汽油[包括与高达约10%(V/V)的乙醇混合的那些]和柴油燃料的硫含量，包括含有高达约10%(V/V)脂肪酸甲酯(FAME)的那些，硫含量在3mg/kg至500mg/kg的范围内。根据该测试方法，可以分析其他产品并测定其他硫含量，但是，对于除汽车燃料以外的产品和超出ISO 20846:2011规定范围的结果，尚未建立精密度数据。卤素在浓度高于约3 500 mg/kg时干扰该检测技术。

ISO 20846:2011 specifies an ultraviolet (UV) fluorescence test method for the determination of the sulfur content of motor gasolines containing up to 3,7 % (m/m) oxygen [including those blended with ethanol up to about 10 % (V/V)], and of diesel fuels, including those containing up to about 10 % (V/V) fatty acid methylester (FAME), having sulfur contents in the range 3 mg/kg to 500 mg/kg. Other products can be analysed and other sulfur contents can be determined according to this test method, however, no precision data for products other than automotive fuels and for results outside the specified range have been established for ISO 20846:2011. Halogens interfere with this detection technique at concentrations above approximately 3 500 mg/kg.
