Asme Section V Article 9 [extra Quality] Access

Visual examiners must be qualified according to (or employer’s written practice compliant with ASNT SNT-TC-1A or CP-189). This includes:

The surface must be lit with at least 100 foot-candles (1000 lux) to ensure adequate visibility. 3.2 Remote Visual Examination

Methods used to clean the surface (e.g., wire brushing, grinding, or solvent wiping). The surface must be free of slag, scale, dirt, or grease that could mask defects.

However, a major point of confusion: Article 9 does not mandate formal SNT-TC-1A certification for visual examination unless the referencing construction code or employer’s written practice requires it. Many auditors still expect documented training and qualification. asme section v article 9

Although modern editions of Section V have streamlined some descriptive text, the technical requirements established by Article 9 regarding viewing conditions remain essential.

The examiner must be capable of distinguishing and differentiating contrast between the colors used in the examination process (typically white, black, red, and yellow). This is usually tested via pseudo-isochromatic plates (Ishihara).

Inspectors must demonstrate the ability to distinguish between colors and differentiate shades of gray, which is critical for identifying subtle heat-tinting, corrosion products, or material changes. 7. Evaluation, Acceptance Standards, and Documentation Visual examiners must be qualified according to (or

When direct access is not possible, remote techniques are used. These must still allow for comparable results, often using cameras, borescopes, or fiber optics. The procedure must demonstrate the capability to detect the minimum required flaw size. 3. Article 9 Implementation in 2026

provides the mandatory requirements for conducting Visual Examination (VT) as a non-destructive testing (NDT) method. It outlines the "how-to" for visual inspections, while the "referencing Code Section" (e.g., Section VIII for pressure vessels or Section I for boilers) provides the actual acceptance standards. Core Requirements

VT requirements with Magnetic Particle (MT) or Penetrant Testing (PT). The surface must be free of slag, scale,

Many facilities qualify an examiner once upon hiring and never recertify them annually, leading to an ASME audit finding.

Cleaning requirements (e.g., removal of oil, rust, or weld spatter).
