Provisional Recommendations are preliminary drafts of IUPAC recommendations. These drafts encompass topics including terminology, nomenclature, and symbols. Following approval, the final recommendations are published in IUPAC’s journal Pure and Applied Chemistry (PAC) or in IUPAC books.
During the commentary period for Provisional Recommendations, interested parties are encouraged to suggest revisions to the recommendation’s author. Following the commentary period, the authors make any final revisions and the recommendation is then published.
