Asme Section V Article 9 Jun 2026

ASME Section V, Article 9 establishes the mandatory requirements for conducting Visual Examination (VT) on pressure vessels, piping, and components, defining procedures for direct, remote, and translucent techniques. It mandates written procedures covering surface preparation, specific lighting intensities, and personnel certification including annual vision tests.

ASME Section V is titled "Nondestructive Examination" (NDE). It contains requirements and methods for all NDE techniques referenced and required by other ASME Boiler and Pressure Vessel Code (BPVC) Sections. These techniques include:

Altering the steps used to clean the component after the inspection is complete. 3. Types of Visual Examination Techniques

ASME Section V Article 9 requires a minimum light intensity of at the examination surface. For critical welds, 1,500–2,000 lux is standard practice.

Checking for slag, porosity, or undercut between passes. asme section v article 9

As of recent updates (T-940), surface preparation is mandatory. The area must be clean, dry, and free from flux, scale, or grease that might mask defects.

Personnel must be capable of reading standard Jaeger Number 1 text (or equivalent) at a distance of no less than 12 inches (300 mm).

This is the traditional method where the inspector's eye is used directly. For it to be valid, the inspector must have access to place their eye within 24 inches (600 mm) of the surface being examined. Furthermore, the line of sight to the surface must be at an angle not less than 30 degrees to the surface. This ensures that the inspector can observe the surface contour and detect flaws like undercut or lack of fusion.

Article 9 distinguishes between different types of visual examinations based on the accessibility and proximity of the inspector to the target surface: ASME Section V, Article 9 establishes the mandatory

All visual examinations must be performed according to a prepared by the manufacturer or user. This procedure must include:

Once the visual examination is completed, the results must be evaluated against the acceptance standards of the referencing code (e.g., ASME Section VIII Division 1). According to Article 9, records must be kept of: and revision. Personnel qualification records. Results (Accepted/Rejected). Final report including the date and specific areas covered. Summary Table: ASME Section V Article 9 Highlights Requirement Method Visual Inspection (VT) Written Procedure Required (T-920) Visual Acuity Test Annual J-1 Jaeger-type (T-940) Direct Distance 6" - 24" (150mm - 600mm) Direct Angle Lighting Minimum 100 foot-candles (1000 lux) Remote Capability Required when direct access is impossible Conclusion

Article 9 establishes the methodology for visual inspections used to determine the condition of a part or component. It is often the first non-destructive examination (NDE) performed, identifying obvious defects before more complex methods like radiographic or ultrasonic testing are applied. 2. Personnel Qualification Requirements

The American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (BPVC) is the standard for safety, reliability, and quality in the pressure equipment industry. Within this framework, ASME Section V governs non-destructive examination (NDE) methods. ASME Section V Article 9 Overview | PDF

Among these methods, establishes the mandatory requirements for conducting visual examinations. Visual examination (VT) is the oldest, most fundamental, and most frequently utilized NDE method in engineering. 1. Scope and Core Purpose of Article 9

The 2023 ASME BPVC includes significant changes across multiple Sections, including Section V. ASME publishes "Summary of Significant Changes" volumes that explain each change, the reason for the action, and the value to the Code user.

A written procedure is mandatory for all visual examinations under ASME Section V, Article 9. This ensures consistency. The procedure must include: What components are being inspected. References: The code sections applied. Personnel Qualification: Requirements for the inspector. Equipment: Tools needed (lighting, gauges, magnifiers). Preparation: Surface cleaning methods. Method: Specific steps for inspection (direct or remote).
