适用范围

1.1 本试验方法涵盖了在表1所示的组成范围内测定天然气和类似气体混合物的化学成分。该测试方法可以缩写为分析含有可忽略不计的己烷和高碳氢化合物的稀薄天然气，或根据需要测定一种或多种组分。
1.2 以SI单位表示的值应视为标准值。本标准中不包括其他计量单位。 1.3本标准并不打算解决与其使用相关的所有安全问题（如果有的话）。本标准的使用者有责任在使用前建立适当的安全和健康实践，并确定监管限制的适用性。
1.1 This test method covers the determination of the chemical composition of natural gases and similar gaseous mixtures within the range of composition shown in Table 1. This test method may be abbreviated for the analysis of lean natural gases containing negligible amounts of hexanes and higher hydrocarbons, or for the determination of one or more components, as required. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
