It is vital to understand how Article 9 interacts with .

The evaluation of radiographic results is a critical step in ASME Section V Article 9. The article provides guidelines for the evaluation of defects or discontinuities, including:

The significance of ASME Section V Article 9 can be summarized as follows:

| Requirement | Essential Variable | Nonessential Variable | |-------------|:-----------------:|:---------------------:| | Change in technique used (direct to/from translucent) | ✓ | | | Direct to remote | ✓ | | | Remote visual aids | ✓ | | | Personnel performance requirements (when required) | | ✓ | | Lighting intensity (decrease only) | ✓ | | | Configurations to be examined and base material product forms (pipe, plate, forgings, etc.) | ✓ | | | Lighting equipment | | ✓ | | Methods or tools used for surface preparation | | ✓ | | Equipment or devices used for a direct technique | | ✓ | | Sequence of examination | | ✓ | | Personnel qualifications | | ✓ |

A critical distinction to understand is that . It only provides the method for the examination. The acceptance or rejection of a weld or component is determined by the referencing construction code (e.g., ASME Section VIII, Div. 1, or ASME B31.3) or by a client specification. In other words, Section V tells you how to look, and Section VIII or B31.3 tells you what to look for and when it's a defect.

The written procedure must, as a minimum, contain the requirements listed in . These include:

Verifying correct assembly and weld contours during manufacturing. Key Requirements for Visual Examination
