ASME BPVC 2025 Section V PDF

Full title and description

ASME BPVC Section V — Nondestructive Examination (2025 Edition). Section V of the ASME Boiler & Pressure Vessel Code specifies mandatory and recommended methods, procedures, acceptance criteria, and documentation practices for nondestructive examination (NDE) used throughout the BPVC and referenced by other Code Sections.

Abstract

This Section provides the requirements and standardized methods for nondestructive examination of materials, welds, and components used in boilers and pressure vessels. It covers visual and surface examinations, volumetric methods, equipment calibration, examiner qualifications, reporting, and criteria used to demonstrate Code conformity for fabrication and in-service inspections. The 2025 edition consolidates recent technical updates and editorial changes applied across the BPVC.

Scope

Section V establishes the standardized nondestructive-examination methods and related requirements that are referenced by other BPVC Sections for qualifying materials, welds, brazed or welded joints, and components. It defines procedure preparation, equipment calibration, examiner qualification and certification, inspection frequencies and sample plans where applicable, reporting formats, and acceptance criteria to ensure consistent, repeatable NDE practices across manufacturing and inspection activities governed by the Code.

Key topics and requirements

• Detailed methods for visual examination (VT), liquid penetrant testing (PT), magnetic particle testing (MT), radiographic testing (RT), ultrasonic testing (UT), eddy current testing (ET), and other recognized NDE techniques.
• Equipment calibration, reference standards, and procedure qualification requirements.
• Acceptance criteria for discontinuities and defect evaluation tied to Code repair/acceptance rules.
• Requirements for examiner qualification, certification, and requalification or continuing assessment.
• Documentation, recordkeeping, and reporting formats required by BPVC and cross-referenced Sections.
• Sampling plans, statistical considerations and when specific NDEs are mandatory versus optional.
• Integration with other BPVC Sections (materials, fabrication, welding, and in-service inspection requirements).

Typical use and users

Used by fabricators, welding shops, NDE service providers, inspection agencies, quality managers, pressure-vessel designers and manufacturers, utilities and owners/operators, and regulatory or certification bodies. Practitioners use Section V to develop inspection procedures, qualify inspection personnel and equipment, perform acceptance inspections, and produce Code-compliant inspection reports.

FAQ

Q: What is this standard?

A: ASME BPVC Section V is the Boiler & Pressure Vessel Code Section that specifies nondestructive-examination methods, procedures, acceptance criteria, and documentation used to examine materials and welds for boilers and pressure vessels.

Q: What does it cover?

A: It covers standardized NDE methods (VT, RT, UT, PT, MT, ET, etc.), equipment and calibration requirements, procedure and personnel qualification, reporting, and acceptance criteria as required or referenced by other BPVC Sections.

Q: Who typically uses it?

A: NDE technicians and supervisors, fabricators, welding engineers, inspection authorities, owners/operators of pressure equipment, third-party inspection agencies, and regulatory bodies that rely on the BPVC for design, construction and certification.

Q: Is it current or superseded?

A: The 2025 Edition of Section V is the active/current code edition for the BPVC cycle published in 2025; users should confirm the applicable edition and any adopted Code Cases or jurisdictional requirements at the time of use.

Q: Is it part of a series?

A: Yes — Section V is one part of the ASME Boiler & Pressure Vessel Code (BPVC), which is comprised of multiple Sections addressing materials, design, fabrication, inspection, testing and certification of boilers and pressure vessels. The BPVC is published on a periodic edition cycle (current edition referenced here is 2025).
