General Chapter <911> Viscosity Reference Corrections in Monographs

Type of Posting: 
Publication Correction

USP is alerting stakeholders that references to General Chapter <911> Viscosity will be changed to refer to General Chapter <911> Viscosity—Capillary Viscometer Methods, <912> Rotational Rheometer Methods, and/or <913> Rolling Ball Viscometer Method to be consistent with a recent change made for General Chapter <911> Viscosity. These references will be changed in seventy monographs.

Modernization for General Chapter <911> Viscosity and two proposals for new General Chapters <912> Rotational Rheometer Methods and <913> Rolling Ball Viscometer Method, which were published in Pharmacopeial Forum 37(4)[Jul-Aug2011] and 37(5)[Sept-Oct2011], have been approved by General Chapters—Physical Analysis Expert Committee. The General Chapter <911> modernization and the two new proposed General Chapters <912> and <913> will become official December 1, 2012 in the Second Supplement to USP 35–NF 30. Therefore, a number of references listing the previous General Chapter number and title should be changed to reflect the corresponding new chapter title and number based on the viscosity procedure specified in the individual monograph.

The monographs containing references to General Chapter <911> Viscosity will be updated in the Second Supplement to USP 35–NF 30. The list of impacted monographs is as follows:
