Scope: This section gives guidelines for the quantitative analysis of natural gas. The measurement ranges of each component of natural gas are given in Table 1. The individual methods described in Part III and subsequent parts of this standard may have a more limited scope of application compared to Table 1, but overall they will be within the broad range given. The scope of application is slightly
