Provisional Recommendations are drafts of IUPAC recommendations.  These drafts encompass topics including terminology, nomenclature, and symbols.  Following approval recommendations are published in IUPAC’s journal Pure and Applied Chemistry (PAC) or books.

While Provisional Recommendations are under the commentary period interested parties are encouraged to suggest revisions to the recommendation's author.  Following the commentary period, the authors complete any final revisions and at which time the recommendation will be published.
