ASME is built with the most modern web standards, which give you a better & more reliable experience.
In the event there is an urgent need for alternative rules concerning materials, construction, or in-service inspection activities not covered by existing Boiler and Pressure Vessel Code rules, or for early implementation of an approved Code revision, ASME may issue a Code Case. Code Cases are effective immediately upon ASME approval and do not expire.
Requests for Code Cases shall provide a Statement of Need and Background Information. The urgency of the Code Case must be defined and it must be confirmed that the request is in connection with equipment that will be ASME stamped, with the exception of Section IX applications. The proposed Code Case should identify the Code Section and Division, and be written as a Question and a Reply in the same format as existing Code Cases. Requests for Code Cases should also indicate the applicable Code Editions and Addenda to which the proposed Code Case applies.
Approved Code Cases are published quarterly. ASME provides a free service
to Code users in viewing Cases that are currently under review as well as
Cases that have been approved but not yet published.
Cases Under Review
Note: Public review is not required for Code Cases, however, comments
on the proposal may be submitted for committee consideration.
