Revision
Revisions are made periodically to ASME Codes to incorporate changes, which appear necessary or desirable, as demonstrated by the experience gained from the application of the Code. Approved revisions will be published periodically in a new edition or in an addendum.
After Code revisions are approved by ASME, may be used beginning with the date of issuance shown on
the Addenda.
Addendum(Addenda)
An addendum provides replacement pages for the current edition of the code or standard.
Addenda often contain a collection of miscellaneous revisions, many of which are editorial, making it more difficult for all users to keep up with the revisions that are important to them.
Errata
Most editions contain a number of editorial changes and perhaps some errata.
Errata include the following:
- Typographical errors or misspelling
- Grammatical errors
- Incorrect publication of approved items, omission by staff of approved items, printer errors, or incorrect publication of an item that was not approved.
- Neglecting to update table for consistency with revision to corresponding text.
Editorial actions are those that make changes to the standard that are not substantive.
Editorial changes do not change the requirement of the standards in any way.
Code Case
Cases are used to provide alternatives to the existing requirements of the code, such as to grant permission to use new materials or alternative constructions.
Cases are often used when the need for a revision is urgent because it is usually faster to generate a case than to revise the code or standard and wait for it to be published in the next new edition or addenda.
Cases can be requested directly by an inquirer or initiated by a committee.
