A: No. This standard is specifically for fusion-welded joints of metallic materials. For castings, refer to ISO 11971. For general metallic materials, refer to ISO 17636 (X-ray) or ISO 17640 (Ultrasonic). Its full title is: A typical inspection following
ISO 17637:2016 establishes international standards for the non-destructive visual testing (VT) of fusion-welded joints in metallic materials, outlining requirements for inspection before, during, and after welding. The standard specifies key conditions, including a minimum 350 lx illumination, a maximum viewing distance of 600 mm, and a minimum viewing angle of 30° to the surface, while requiring compliance with WPS specifications.
