Asme Section V Article 9 File
Here’s a draft of content about ASME Section V, Article 9, suitable for a technical blog post, training summary, or internal procedure overview.
Examination Procedure Requirements
Article 9 is unique because it does not mandate a detailed written procedure for direct visual examination (unlike RT or UT). However, for remote visual examination, a procedure is required. Practical wisdom suggests: asme section v article 9
- Direct Visual Examination: The eye is within 24 inches (610 mm) of the surface, with a viewing angle not less than 30° from the surface. Typically used with aids like mirrors or borescopes.
- Remote Visual Examination: Uses cameras, fiberscopes, or other tools when direct access is impossible. Requires a resolution chart verification.
- Illumination: Minimum 100 foot-candles (1100 lux) at the examination surface for direct visual.
- Direct Visual Examination: The examination is conducted with the eye placed within 24 inches (610 mm) of the surface, and at an angle not less than 30 degrees to the surface.
- Remote Visual Examination: Used when direct access is not possible (e.g., inside small diameter pipes or vessels). This utilizes equipment like borescopes, fiberscopes, or cameras.
- Translucent Visual Examination: Used to view the silhouette of components (typically tubing) for blockages or obstructions using a light source placed behind the object.
