Presenters: Jim Sowinski, P.E., Vice President of Codes & Standards; Principal Engineer II
Date: Thursday, October 16 | 11:00 AM EDT

The 2025 edition of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, Section VIII, Division 1 (ASME VIII-1) and Section VIII, Division 2 (ASME VIII-2) were published in July 2025. There are significant changes that will be implemented in the 2025 edition which reflect years of planning, organizing, and execution to enhance the use and reach of these standards. The intent of this presentation is not to provide an exhaustive list or synopsis of changes, but rather to focus on aspects of the changes that are shaping the direction of future updates of the standards as recommended by the ASME BPV Section VIII Reshape Project. The presentation will, however, highlight specific changes to ASME VIII-1, Appendix 47 associated with the requirements for pressure vessel designers and the removal of the two-class vessel structure of ASME VIII-2, which impacts industry.
