Natural gas – Gas sampling

This document establishes a standardized methodology for the sampling of natural gas within the gas supply and utilization sectors. It provides specific procedures and technical requirements to ensure that collected samples accurately represent the characteristics of the entire gas flow. The scope of this work covers various sampling locations and equipment used to extract representative portions of gas for subsequent analysis. Adherence to these guidelines is essential for maintaining data integrity during quality control, custody transfer operations, and regulatory compliance processes. The approach outlined aims to minimize errors introduced during the collection phase, thereby supporting reliable measurements of gas composition and physical properties. By following the prescribed steps, operators can ensure consistency and safety in handling gaseous fuels across different stages of the supply chain.
