It also covers the suppliers examination responsibilities, requirements of the authorized inspectors (AI) as well as the requirements for the qualification of personnel, inspection and examinations. ASME BPVC Section VIII - Rules for Construction of Pressure Vessels This section of the ASME BPVC consists of 3 divisions. ASME Section VIII Division 1 Div. 1 covers the mandatory requirements, specific prohibitions and nonmandatory guidance for materials, design, fabrication,
