Asme Section V Article 9 [upd] Jun 2026
Inadequate lighting is a primary cause of missed defects. Article 9 establishes strict quantitative baselines for illumination:
As the ASME Boiler and Pressure Vessel Code continues to evolve, Article 9 will adapt to incorporate emerging technologies while maintaining its essential role in safeguarding industrial safety. Whether applied to a small pressure vessel, a complex nuclear component, or a critical pipeline, the principles enshrined in Article 9 remain constant: qualified personnel, validated procedures, adequate viewing conditions, proper surface preparation, and thorough documentation.
Ensuring adequate, consistent illumination for accurate assessment. 6. Summary of Key Requirements (T-940) Requirement Specification Procedure Mandatory Written Procedure Vision Exam Annual J-1 Jaeger-type Test Distance 6" – 24" ( Angle
By 2026, technology has integrated deeper into visual testing. While Article 9 remains strict, industry practice now often uses: asme section v article 9
The written procedure must be developed by the manufacturer or fabricator and must detail every variable affecting the inspection quality. It must address: The specific type of components to be examined. The physical configuration and surface conditions required.
Used when access is restricted, or the surface is too far away. This involves using equipment like: Mirrors and magnifying glasses. (rigid or flexible). Video cameras (CCTV). Remote Operated Vehicles (ROVs) .

Your Article 9 exam is worthless without a report. The mandatory records for Visual Examination include:
Technicians must verify light intensity using a calibrated light meter prior to starting the examination, or use a verified, consistent light source. Access and Viewing Angles
While not strictly defined in Article 9 itself, it is common for the employer to certify personnel based on guidelines in ASME Section V, Article 1 or SNT-TC-1A (ASNT). 4. Written Procedure Requirements (T-921) While Article 9 remains strict, industry practice now
The surface must be illuminated with a minimum of 100 foot-candles (1000 lux). E. Remote Visual Examination
