1 INTRODUCTION (a) The following information provides guidance to Code users for submitting technical inquiries to the committees. See Guideline on the Approval ofNew 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 Interpretations, as described below. (1) Code Revisions. Code revisions are considered to accommodate technological developments, address administra- tive requirements, incorporate Code Cases, or to 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 pre- scribe mandatory requirements in the same sense as the text of the Code. However, users are cautioned that not all jur- isdictions 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 alternative rules prior to incorporation directly into the Code (3) Code Interpretations. Code Interpretations provide 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 where ex- isting Code text does not fully convey the meaning 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. (b) The Code rules, Code Cases, and Code Interpretations established by the committees are not to be considered as approving, recommending, certifying, or endorsing any proprietary or specific design, or as limiting in any way the free- dom ofmanufacturers, constructors, or owners to choose any method ofdesign or any form ofconstruction that conforms to the Code rules. (c) Inquiries that do not comply with these provisions or that do not provide sufficient information for a committee’s full understanding may result in the request being returned to the inquirer with no action. 2 INQUIRY FORMAT Submittals to a 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 ofthe inquiry, being sure to include reference to the applicable Code Section, Division, Edition, Addenda (if applicable), paragraphs, figures, and tables. Pre- ferably, provide a copy of the specific referenced portions of the Code. (c) Presentations. The inquirer may desire or be asked to attend a meeting ofthe committee to make a formal presenta- tion or to answer questions from the committee members with regard to the inquiry. Attendance at a committee meeting shall be at the expense ofthe inquirer. The inquirer’s attendance or lack ofattendance at a meeting shall not be a basis for acceptance or rejection of the inquiry 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 ofthe Code that require revision and submit a copy of the appropriate rules as they appear in the Code, marked up with the proposed revision. For additions, provide the recommended wording referenced to the existing Code rules. (b) Statement ofNeed. Provide a brief explanation of the need for the revision or addition. (c) Background Information. Provide background information to support the revision or addition, including any data or changes in technology that form the basis for the request that will allow the committee to adequately evaluate the pro- posed revision or addition. Sketches, tables, figures, and graphs should be submitted as appropriate. When applicable, identify any pertinent paragraph in the Code that would be affected by the revision or addition and identify paragraphs in the Code that reference the paragraphs that are to be revised or added. 4 CODE CASES Requests for Code Cases shall provide a Statement ofNeed and Background Information similar to that defined in 3(b) and 3(c), respectively, for Code revisions or additions. The urgency ofthe Code Case (e.g., project underway or imminent, new procedure, etc.) must be defined and it must be confirmed that the request is in connection with equipment that will bear the Certification Mark, with the exception of Section XI 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 (ifapplicable) to which the proposed Code Case applies.
