ISO 13664:1997 PDF

This International Standard specifies requirements for magnetic particle inspection of the end/-bevel face at the ends of seamless and welded steel tubes for pressure purposes, for the detection of laminar imperfections.

It is intended that this International Standard be used to detect, on the end/bevel face at the ends of plain- end and bevelled-end tubes, laminar imperfections which may interfere with subsequent fabrication and inspection operations (e.g. welding, ultrasonic inspection of the butt welds, etc.). This International Standard may be used as an alternative to, or in addition to, ISO 11496.

This International Standard may also be used for the detection of imperfections, other than laminar imperfections, on the end/bevel face. In this case, magnetization shall be applied in the direction essentially perpendicular to the orientation of the particular imperfections to be detected.
