Scope
EN ISO 17640
Ultrasonic Non-Destructive Testing
Ultrasonic testing (UT) detects internal flaws, wall thickness, and material discontinuities in metallic and composite components without damaging them. EN ISO 17640 covers manual UT of fusion-welded joints; phased-array (PAUT) and time-of-flight diffraction (TOFD) extend the technique to automated flaw sizing. UT is essential for pressure equipment, pipelines, and structural welds.
What it measures
- Internal flaw detection (cracks, inclusions, porosity)
- Flaw location, size, and orientation
- Wall thickness measurement
- Bond integrity in bonded structures
- Weld root and fusion defects
