(a) This Appendix provides guidance to Code users for submitting technical inquiries to the Committee. See Guideline on the Approval of New Materials Under the ASME Boiler and Pressure Vessel Code in Section II, Parts C and D for additional requirements for requests involving adding new materials to the Code. Technical inquiries include requests for revisions or additions to the Code rules, requests for Code Cases, and requests for Code inter- pretations, as described below. (1) Code Revisions. Code revisions are considered to accommodate technological developments, address admin- istrativerequirements, incorporateCodeCases, orto clarify Code intent. (2) Code Cases. Code Cases represent alternatives or additions to existing Code rules. Code Cases are written as a question and reply, and are usually intended to be incorporated into the Code at a later date. When used, Code Cases prescribe mandatory requirements in the same sense as the text ofthe Code. However, users are cautioned that not all jurisdictions or owners automatically accept Code Cases. The most common applications for Code Cases are: (a) to permit early implementation of an approved Code revision based on an urgent need (b) to permit the use of a new material for Code construction (c) to gain experience with new materials or alter- native rules prior to incorporation directly into the Code (3) Code Interpretations. Code Interpretations pro- vide clarification of the meaning of existing rules in the Code, and are also presented in question and reply format. Interpretations do not introduce new requirements. In cases whereexisting Codetextdoes notfully convey themeaning that was intended, and revision of the rules is required to support an interpretation, an Intent Interpretation will be issued and the Code will be revised.
(c) Inquiries that do not comply with the provisions of this Guideline or that do not provide sufficient information for the Committee’s full understanding may result in the request being returned to the inquirer with no action. 2 INQUIRY FORMAT Submittals to the Committee shall include: (a) Purpose. Specify one of the following: (1) revision of present Code rules (2) new or additional Code rules (3) Code Case (4) Code Interpretation (b) Background. Provide the information needed for the Committee’s understanding of the inquiry, being sure to include reference to the applicable Code Section, Division, Edition, Addenda, paragraphs, figures, and tables. Prefera- bly, provide a copy of the specific referenced portions of the Code. (c) Presentations. The inquirer may desire or be asked to attend a meeting of the Committee to make a formal presentation or to answer questions from the Committee members with regard to the inquiry. Attendance at a Com- mittee meeting shall be at the expense of the inquirer. The inquirer’s attendance or lack of attendance at a meeting shallnotbeabasis foracceptance orrejectionoftheinquiry by the Committee. 3 CODE REVISIONS OR ADDITIONS Requests for Code revisions or additions shall provide the following: (a) Proposed Revisions or Additions. For revisions, identify the rules of the Code that require revision and submit a copy ofthe appropriate rules as they appear in the Code, marked up with the proposed revision. Foradditions, provide the recommended wording referenced to the existing Code rules.

TheurgencyoftheCode Case(e.g., projectunderway or imminent, new procedure, etc.) must be defined and it must be confirmed that the request is in connection with equipment that will be ASME stamped, with the exception ofSectionXI applications. TheproposedCodeCase should identify the Code Section and Division, and be written as a Question and a Reply in the same format as existing Code Cases.
