: The ASME PTB‑3:2022 "Section VIII‑Division 2 Example Problem Manual" is an invaluable resource that provides example problems illustrating the use of both design‑by‑rule and design‑by‑analysis methods in both SI and US Customary units.
This is the core strength of Division 2. When vessel geometries are complex, or cyclic loading is a factor, standard rules do not apply. Designers must use numerical analysis techniques to validate the structure. Three types of analysis are widely deployed:
Like the UDS, the MDR must be certified by an RPE to verify compliance with Division 2 rules. Division 1 vs. Division 2: A Comparison

The most significant update centers on Part 5—Design‑By‑Analysis. The 2025 edition has completely overhauled this section, aligning it with modern engineering practices and other industry standards. Key improvements include a major editorial revision to improve clarity and conformance with the ASME Style Guide, the reinstatement of Bearing and Shear Stress Limits from the 2004 Edition (pre‑2007 rewrite), and updated fatigue analysis methods to harmonize with API 579‑1/ASME FFS‑1 (2021). The ratcheting assessment has been substantially updated with changed elastic analysis ratcheting limits and a new method based on Bree Diagrams. The most significant addition is a new section titled which introduces new damage modes including stress rupture from load‑controlled loads, creep buckling, creep‑fatigue screening methods, and creep ratcheting.
Division 2 work is not ideal for standard, low-pressure utility tanks due to the high cost of engineering analysis. However, it is highly economical and necessary under the following conditions:
Division 2 is titled “Alternative Rules.” It provides an alternative to the traditional "design by rule" methodology found in Division 1. The work associated with Division 2 is characterized by the following: : The ASME PTB‑3:2022 "Section VIII‑Division 2 Example
