ASME BPVC Section V 2025 Revisions: Key Changes NDT Engineers Must Know (Mandatory from January 2026)

The ASME Boiler & Pressure Vessel Code (BPVC) Section V, which defines nondestructive examination requirements, was substantially revised in its 2025 edition and became mandatory from January 1, 2026. The updates reflect the adoption of advanced UT techniques, digital workflow integration, and tighter personnel qualification rules. NDT engineers working in the oil, gas, and petrochemical sectors should understand what changed and how it affects day-to-day work.

Formal Adoption of TFM/FMC

Total Focusing Method (TFM) and Full Matrix Capture (FMC) have been formally incorporated into Article 4 (Ultrasonic Examination). Procedures that used to require Code Case recognition can now be implemented under Section V directly, lowering the administrative burden for clients who want to leverage advanced PAUT imaging.

Enhanced Digital Radiography Acceptance Criteria

Article 2 (Radiographic Examination) now includes updated guidance on Computed Radiography (CR) and Digital Detector Array (DDA) systems, harmonizing image quality indicators and detector resolution requirements with global standards. Users can more reliably transition from conventional film radiography to digital workflows while maintaining compliance.

Personnel Qualification Updates

• ASNT SNT-TC-1A (2020) is now referenced as an acceptable written practice template.
• CP-189 practical examination requirements have been clarified to emphasize hands-on competence.
• Digital procedure qualification records must now be stored in a format auditable during Authorized Inspector (AI) reviews.

Article 14: Examination System Qualification

Article 14 defines requirements for qualification of examination systems using demonstration testing. The 2025 edition streamlines the qualification process for PAUT-TFM systems and introduces clearer acceptance criteria for Performance Demonstration Qualification (PDQ), particularly benefiting inspection contractors who frequently cross between nuclear, fossil, and petrochemical clients.

Impact on Japanese Operators

Most Japanese refineries follow API/ASME-based inspection programs in parallel with METI-regulated Japanese codes. The 2025 Section V revisions reach Japan primarily through subcontractor qualification requirements and through imported equipment whose original certifications refer to ASME. Inspection service providers should: (1) update written practices in line with the new SNT-TC-1A reference, (2) evaluate whether TFM/FMC procedures should be formally added, and (3) ensure digital recordkeeping workflows survive audit by Authorized Inspectors.

Summary

The ASME BPVC Section V 2025 revisions accelerate the shift toward advanced UT and digital workflows. The changes are additive rather than disruptive, but compliance now requires updated procedures and clear audit trails. Urisol Inc. works with plant operators and inspection contractors to align their written practices and qualification records with the 2025 edition.
