This International Standard specifies techniques for detection of surface imperfections in welds in
ferromagnetic materials, including the heat affected zones, by means of magnetic particle testing. The
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.
This International Standard does not specify acceptance levels of the indications. Further information on acceptance levels for indications may be found in EN 1291 or in product or application standards.
