标准摘要
[中文适用范围]： 本文件规定了卡尔费休法测定水含量的库仑分析程序。 本方法适用于天然气及其他不与卡尔费休（KF）试剂反应的气体。 它适用于5mg/m3至5000mg/m3之间的水浓度。 体积以温度 273,15 K (0 °C) 和压力 101,325 kPa (1 atm) 表示。 [外文原描述]： This document specifies a coulometric procedure for the determination of water content by the Karl Fischer method. The method is applicable to natural gas and other gases which do not react with Karl Fischer (KF) reagents. It applies to water concentrations between 5 mg/m 3 and 5 000 mg/m 3 . Volumes are expressed at temperature of 273,15 K (0 °C) and a pressure of 101,325 kPa (1 atm).
