Scope

This document provides guidance and recommendations for sampling, analysis, and metering of hydrogen-blended natural gas in pipeline transportation, and provides information related to key points that need to be considered.
This document is applicable to hydrogen-blended natural gas with a hydrogen content (mole fraction) not exceeding 10.0% (where the hydrogen and natural gas have been fully mixed and are uniform). Hydrogen-blended natural gas with a hydrogen content exceeding 10.0% can refer to this document.
Note: Unless otherwise specified, the hydrogen content described in this document is measured in mole fractions.
This document is applicable to the quality analysis and flow measurement of hydrogen-blended natural gas in handover metering systems and transmission and distribution metering systems of long-distance natural gas pipelines and urban gas pipelines.
