Asme Section V Article 9 !link! Official

If you are looking for acceptance criteria for a pressure vessel weld, do not look in Article 9. Article 9 will tell you how bright your light must be (100 foot-candles minimum) and how long you must stare (retinal persistence), but it will not tell you if a crack is allowed. For that, you must refer to the referencing Code Section (e.g., ASME Section VIII, Div. 1, Table UW-35).

A list of gauges, micrometers, calipers, or templates used to measure linear dimensions, undercut, or weld reinforcement. Personnel Qualification and Vision Requirements

Article 9 gives interpretation rules and acceptance thresholds tied to type, size, and distribution of indications. Key points commonly applied (refer to the Code for exact values and tables):

ASME Section V tells you how to perform the examination. The acceptance or rejection criteria are governed by the referencing construction or client code (such as ASME Section VIII for pressure vessels, ASME B31.3 for process piping, or API standards).

: Personnel must undergo annual vision examinations to ensure they can read standard J-1 letters (Jaeger test) or equivalent at a distance of at least 12 inches. Training & Certification

| Discontinuity Type | Acceptance Limit (Illustrative) | |------------------|--------------------------------| | Cracks | Not allowed | | Incomplete fusion or penetration | Not allowed | | Undercut | ≤ 1/32 in. deep (except where larger is permitted by referencing code) | | Porosity | Size and distribution per code case | | Surface roughness | No sharp notches (smooth blend required) |
