The 2007 Code is available only in the loose-leaf format; accordingly, the Addenda will be issued in the loose-leaf, replacement-page format. INTERPRETATIONS ASME issues written replies to inquiries concerning interpretation of technical aspects of the Code. The Inter- pretations for each individual Section will be published separately and will be included as part of the update service to that Section. Interpretations of Section III, Divisions 1 and 2, will be included with the update service to Subsec- tion NCA. iv Interpretations of the Code are distributed annually in July with the issuance of the edition and subse- quent addenda. Interpretations posted in January at www.cstools.asme.org/interpretations are included in the July distribution. CODE CASES The Boiler and Pressure Vessel Committee meets regu- larly to consider proposed additions and revisions to the Code and to formulate Cases to clarify the intent of existing requirements or provide, when the need is urgent, rules for materials or constructions not covered by existing Code rules. Those Cases that have been adopted will appear in the appropriate 2007 Code Cases book: “Boilers and Pressure Vessels” and “Nuclear Components.” Supple- ments will be sent automatically to the purchasers of the Code Cases books up to the publication of the 2010 Code.
