Geographic information. Observations and measurements Ingestion-build-135476 polybrominated biphenyls (PBB) and polybrominated1 Scope This International Standard defines a conceptual schema for observations, and for features involved in sampling when making observations. These provide models for the exchange of information describing observation acts and their results, both within and between different scientific and technical communities. Observations commonly involve sampling of an ultimate feature of interest. This International Standard defines a common set of sampling
