ISO/TR 27918:2018 is designed to be an information resource for the potential future development of a standard for overall risk management for CCS projects. The risks associated with any one stage of the CCS process (capture, transportation, or storage) are assumed to be covered by specific standard(s) within ISO/TC 265 and other national and/or international standards. For example, the risks…

ISO 20579-4:2018 identifies information to be reported in a datasheet, certificate of analysis, report or other publication regarding the handling of nano-objects in preparation for surface chemical analysis. This information is needed to ensure reliability and reproducibility of analyses needed to advance research and technology using these materials, and for obtaining appropriate understanding…
