Current and "LIVE"
The BPVC is kept current by Boiler and Pressure Committees, a volunteer group of more than 1,000 technical experts. The Committees meet regularly to consider requests for interpretations, revisions, and to develop new rules. In the formulation of its rules and in the establishment of maximum design and operating pressures, the Committees consider technological advances including materials, construction, methods of fabrication, inspection, certification, and overpressure protection.

2013 Edition — No Addenda Service
Changes to the 2013 Edition of the BPVC are incorporated into the appropriate page and each affected area is identified with a designator corresponding to the new Edition. Each Section of the 2013 Edition includes a Summary of Changes that lists the material affected by the change, plus the nature of the change.
All Sections and Code Case Supplements are issued in loose-leaf format.
ASME issues written replies to inquiries concerning interpretation of technical aspects of the BPVC. The Interpretations for each individual Section will be published separately and will be included with the update service to that Section. Interpretations of Section III, Divisions 1 and 2 will be included with the update service to Subsection NCA. Interpretations of the BPVC are posted in January and July at: cstools.asme.org/interpretations.cfm
Code Case Supplements
Code Cases clarify the intent of existing requirements or provide, when the need is urgent, rules for materials or constructions not covered by existing BPVC rules. Cases will appear in the applicable Code Cases book: "(1)" Boilers and Pressure Vessels or "(2)" Nuclear Components. Supplements will be sent automatically four times per year to the purchasers of the Code Cases books up to the publication of the 2015 BPVC.
