ISO 17637
This report examines , the international standard for the non-destructive visual testing of fusion-welded joints . It outlines the procedural requirements, equipment standards, and documentation necessary for effective weld inspection. 1. Scope and Objective
- Illumination: The standard specifies the minimum light intensity required on the surface being inspected (typically $\geq$ 500 lux for general inspection and $\geq$ 1000 lux for critical inspection or small anomalies).
- Visual Acuity: It sets requirements for the inspector's eyesight, including near-vision acuity tests (often reading the J1 or J2 level on a standard chart) and color vision tests.
- Equipment: It defines the use of magnifiers, mirrors, video cameras, and gauges (such as weld profile gauges) to aid the inspection.
- Surface Condition: It dictates that the surface must be free from slag, spatter, and coating that might obscure defects.
