标准范围

本文件提供了确保输送至输配电网的天然气和天然气替代品样品代表其分配质量的方法。注意事项为确保标准中考虑到特定气体，请参见附件A.本文件适用于测量和监测互换性标准、能源含量和网络进入条件的现场和地点的采样，尤其适用于跨境和财政测量站。它是天然气处理中控制应用和痕量组分测量的重要来源。本文件仅适用于天然干气（单相-通常是通过天然气管道输送的气体）取样。有时，天然气流可能夹带液态烃。尝试对湿天然气流进行采样，可能会导致流成分分析中出现额外的不确定因素。湿气（两相或三相）流取样不在本文件范围内。本文件不适用于与气体取样相关的安全问题。

This document gives means for ensuring that samples of natural gas and natural gas substitutes that are conveyed into transmission and distribution grids are representative of the mass to which they are allocated.NOTE      To ensure that a particular gas is taken into account in the standard, please see Annex A.This document is applicable for sampling at sites and locations where interchangeability criteria, energy content and network entry conditions are measured and monitored and is particularly relevant at cross border and fiscal measurement stations. It serves as an important source for control applications in natural gas processing and the measurement of trace components.This document is applicable to natural dry gas (single phase - typically gas transiting through natural gas pipelines) sampling only. On occasion a natural gas flow can have entrained liquid hydrocarbons. Attempting to sample a wet natural gas flow introduces the possibility of extra unspecified uncertainties in the resulting flow composition analysis. Sampling a wet gas (two or three phases) flow is outside the scope of this document.This document does not apply to the safety issues associated with gas sampling.
