适用范围

本标准包括以下各项的测定： 使用气相色谱仪（GC）测定表1所列范围内天然气和类似气体混合物的化学成分。这三列表示原始表1，但将值分为三个不同的组。第一组浓度低于循环项目（RR-188）获得的数据。 第二组是循环项目（RR-188）中使用的浓度。在该标准中的精度声明中列出的方程覆盖了在离群值被去除之后在中间列中列出的范围。第三组浓度高于循环项目（RR-188）获得的数据。 This standard covers the determination of the chemical composition of natural gas and similar gaseous mixtures within the ranges listed in Table 1, using a Gas Chromatograph (GC). The three olumns represent the original Table 1, but separate the values to three distinct groups. The first group is concentrations lower than the data obtained from the round-robin project (RR-188). The second group is concentrations used in the roundrobin project (RR-188). The equations listed in the precision statement in this standard cover the range listed in the middle column, after outliers were removed. The third group is concentrations higher than the data obtained from the round-robin project (RR-188).
