Non-destructive testing of welds. Magnetic particle testingWhat is ISO 17638 about? ISO 17638 specifies techniques for the detection of surface imperfections in welds in ferromagnetic materials, including the heat affected zones, by means of magnetic particle testing. These techniques are suitable for most welding processes and joint configurations. Variations in the basic techniques that will provide a higher or lower test sensitivity are described in Annex A. Note: ISO 17638 does not specify acceptance
