What Happens When Standards Have Errors?
Sometimes a standard may need a technical or editorial correction to be made. As part of the standards development process, IEEE can easily accommodate this by issuing a corrigenda or errata Sheet.
Corrigenda correct a technical error, as well as a semantic error and require a PAR and to go through a consensus ballot.
Errata sheets are separate pages issued after an IEEE standard has been approved and published. They correct typographical or editorial errors that have been found in that particular IEEE standard. Errata do not require a PAR and or a consensus ballot.
