Description of Origin of Change Key Icons

USP-NF is revised continuously. However, more frequent revisions occur through one of USP's Accelerated Revision processes: Errata, Interim Revision Announcements (IRAs), Revision Bulletins, and Harmonization. Notices of these revisions are posted in the new USP-NF/PF Online without you requiring to go to other USP sites. These revisions to an existing document supersede the official text and are indicated by the following key icons:

Note: Always check for updated official text through START HERE > NEW AND CHANGED Navigation Bar.
 

The icons below indicate the origin of change.
 

Icon	Name
RB	Revision Bulletin
IRA	Interim Revision Announcements
E	Errata
H	Harmonization

Note: Icons appear for general chapter, monographs, and reagents documents, and only appear when the standard contains recent revisions of the type indicated by the letters in the icon. For more information on these revision types, please see the page on revision definitions here. An example of a document showing a "Revision Bulletin" update in a search result is shown below:
