On October 4, the ISO 10715:2022 standard on gas sampling was published. The purpose of this standard is to provide good sampling practices to obtain a representative sample of the gas to be analyzed.
This international standardization work was conducted by the “Sampling” working group (WG 20), led by Alice VATIN of RICE, within the ISO/TC 193/SC 1 technical subcommittee “Natural Gas Analysis”.
The 2022 version is the second edition of this gas sampling standard, thefirst version dating from 1997. The new version has thus made it possible to integrate new developments in terms of sampling technologies, to explain the phenomena that can degrade the quality of the sample, and to broaden the scope to include trace compounds from biomethane.
To carry out this revision work, the WG 20 experts met a dozen times over the last three years and processed more than 350 technical and editorial comments from the various national standards bodies!
The outcome of this collective work was possible thanks to the perseverance of the technical experts as well as the precious help of the Bureau de Normalisation Gazière (BNG), which had the secretariat of the working group.
The gas sampling standard has a long life ahead of it. Its systematic review will take place in 2027. No doubt it will be revised at that time to incorporate the knowledge gained in the meantime on the trace compounds of the various renewable gases.
