Reference Standards Under Development

The following list features never-before-released Reference Standards currently under development at USP and their anticipated release dates. This list is compiled once per calendar quarter (four times per year). The list is provided in downloadable xls format for your convenience.

Note: Anticipated release dates are estimates made at the time the list is compiled. Future Reference Standards may be added to or withdrawn from the list at any time, and Reference Standards may be released sooner or later than the estimated dates stated here. Reference Standards listed here may be used by more than one compendium now or in the future.
