22 Section VIII: Division 2—Alternative Rules
Download citation file:
Chapter 22, initially authored by Kamran Mokhtarian for the previous two editions has been revised in its entirety by David A. Osage, Clay D. Roldery, Guido G. Karcher, Thomas P. Pastor, Robert G. Brown and Philip A. Henry. This revision covers the 2007 Edition of Section VIII, Division 2. The 2007 Edition is a complete rewrite of the standard, a project that began in 1998 and took nine years to complete. The decision to completely rewrite VIII-2 was made so that the standard could be modernized with regard to the latest technical advances and pressure vessel construction, and also be structured in a way to make it more user-friendly for both users and the committees that maintain it. The 2007 Edition of Section VIII, Division 2 is the result of an extensive collaborative effort involving ASME Volunteers and Staff, the Pressure Vessel Research Council and The Equity Engineering Group.
Mr. David A. Osage was the lead author for the new standard, and he made significant contributions to the design by rule and design by analysis chapters (Parts 4 and 5). He also had responsibility for the assembly of all material that ultimately made up the 9 parts of the new standard: 1. General Requirements, 2. Responsibility and Duties, 3. Materials Requirements, 4. Design by Rule Requirements, 5. Design by Analysis Requirements, 6. Fabrication Requirements 7. Inspection and Examination Requirements, 8. Pressure Testing Requirements, 9. Pressure Vessel Overpressure Protection.
This chapter provides an overview of the development of the new standard, its organization, and a detailed description of each of the nine parts. Emphasis is given to those areas of the standard where new technology was introduced.
