1 INTRODUCTION (a) The following information provides guidance to Code users for submitting technical inquiries to the applicable Boiler and Pressure Vessel (BPV) Standards Committee (hereinafter referred to as the Committee) . See the guidelines on approval of new materials under the ASME Boiler and Pressure Vessel Code in Section II, Part D for requirements for requests that involve adding new materials to the Code. See the guidelines on approval of new welding and brazing ma- terials in Section II, Part C for requirements for requests that involve adding new welding and brazing materials (“con- sumables”) to the Code. Technical inquiries can include requests for revisions or additions to the Code requirements, requests for Code Cases, or requests for Code Interpretations, as described below: (1 ) Code Revisions. Code revisions are considered to accommodate technological developments, to address admin- istrative requirements, to incorporate Code Cases, or to clarify Code intent. (2) Code Cases. Code Cases represent alternatives or additions to existing Code requirements. Code Cases are writ- ten 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 of the Code. However, users are cautioned that not all regulators, j urisdictions, or Owners automatically accept Code Cases. The most common applications for Code Cases are as follows: (-a) to permit early implementation of an approved Code revision based on an urgent need (-b) to permit use of a new material for Code construction (-c) to gain experience with new materials or alternative requirements prior to incorporation directly into the ð17Þ Code (3) Code Interpretations (-a) Code Interpretations provide clarification of the meaning of existing requirements in the Code and are pre- sented in Inquiry and Reply format. Interpretations do not introduce new requirements. (-b) If existing Code text does not fully convey the meaning that was intended, or conveys conflicting require- ments, and revision of the requirements is required to support the Interpretation, an Intent Interpretation will be issued in parallel with a revision to the Code. (b) Code requirements, Code Cases, and Code Interpretations established by the Committee are not to be considered as approving, recommending, certifying, or endorsing any proprietary or specific design, or as limiting in any way the freedom of manufacturers, constructors, or Owners to choose any method of design or any form of construction that conforms to the Code requirements. (c) Inquiries that do not comply with the following guidance or that do not provide sufficient information for the Com- mittee’s full understanding may result in the request being returned to the Inquirer with no action. 2 INQUIRY FORMAT Submittals to the Committee should include the following information: (a) Purpose. Specify one of the following: (1 ) request for revision of present Code requirements (2) request for new or additional Code requirements (3) request for Code Case (4) request for Code Interpretation (b) Background. The Inquirer should provide the information needed for the Committee’s understanding of the In- quiry, being sure to include reference to the applicable Code Section, Division, Edition, Addenda (if applicable) , para- graphs, figures, and tables. Preferably, the Inquirer should provide a copy of, or relevant extracts from, the specific referenced portions of the Code.
(c) Presentations. The Inquirer may desire to attend or be asked to attend a meeting of the Committee to make a for- mal presentation or to answer questions from the Committee members with regard to the Inquiry. Attendance at a BPV Standards Committee meeting shall be at the expense of the Inquirer. The Inquirer’s attendance or lack of attendance at a meeting will not be used by the Committee as a basis for acceptance or rej ection of the Inquiry by the Committee. How- ever, if the Inquirer’s request is unclear, attendance by the Inquirer or a representative may be necessary for the Com- mittee to understand the request sufficiently to be able to provide an Interpretation. If the Inquirer desires to make a presentation at a Committee meeting, the Inquirer should provide advance notice to the Committee Secretary, to ensure time will be allotted for the presentation in the meeting agenda. The Inquirer should consider the need for additional audiovisual equipment that might not otherwise be provided by the Committee. With sufficient advance notice to the Committee Secretary, such equipment may be made available. 3 CODE REVISIONS OR ADDITIONS Requests for Code revisions or additions should include the following information: (a) Requested Revisions or Additions. For requested revisions, the Inquirer should identify those requirements of the Code that they believe should be revised, and should submit a copy of, or relevant extracts from, the appropriate require- ments as they appear in the Code, marked up with the requested revision. For requested additions to the Code, the In- quirer should provide the recommended wording and should clearly indicate where they believe the additions should be located in the Code requirements. (b) Statement of Need. The Inquirer should provide a brief explanation of the need for the revision or addition. (c) Background Information. The Inquirer should 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 ade- quately evaluate the requested revision or addition. Sketches, tables, figures, and graphs should be submitted, as appro- priate. The Inquirer should identify any pertinent portions of the Code that would be affected by the revision or addition and any portions of the Code that reference the requested revised or added paragraphs.
