Boiler and Pressure Vessel Code
2013 Edition

About the Code
The International Boiler and Pressure Vessel Code establishes rules of safety — relating only to pressure integrity — governing the design, fabrication, and inspection of boilers and pressure vessels, and nuclear power plant components during construction. The objective of the rules is to provide a margin for deterioration in service. Advancements in design and material and the evidence of experience are constantly being added.

A Century of Public Safety
Originating in 1914, the ASME Boiler and Pressure Vessel Code is now adopted in part or in its entirety, by all 50 states and numerous municipalities and territories of the United States and all the provinces of Canada. More than 100,000 copies of the BPVC are in use in 100 countries around the world, with translations into a number of languages. The boiler and pressure-vessel sections of the BPVC have long been considered essential within such industries as electric power-generation, petrochemical, and transportation, among others.

ASME has also played a vital role in supporting the nuclear industry since its inception, when ASME codes, standards and conformity assessment programs, originally developed for fossil fuel-fired plants, were applied to nuclear power-plant construction. Its widely-adopted BPVC Section III, Rules for Construction of Nuclear Facility Components, celebrates 50 years in 2013. Presently, half of the world's nuclear power plants incorporate all or portions of ASME nuclear codes and standards in their construction, operation, and/or maintenance.

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. Interpretations

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.
