Scope
Default European pressure vessel code (alternative to ASME VIII).
Key requirements (8)
- European unfired pressure vessel standard, harmonized with PED 2014/68/EU.
- Parts: 1 General, 2 Materials, 3 Design, 4 Fabrication, 5 Inspection, 6 Cast Iron, 8 Aluminum.
- Two design routes: Design by Formulas (DBF) and Design by Analysis (DBA).
- Testing groups 1–4 with progressively reduced NDE for Group 4 (lower duty).
- Hydrostatic test: 1.25 × max allowable pressure × (f_test/f_design).
- Joint coefficient z replaces ASME's joint efficiency E (1.0 / 0.85 / 0.7).
