scope:

Defines eddy current examination techniques for detection of surface breaking and near surface planar imperfections, mainly in ferritic materials (weld material, heat affected zones, parent materials). This eddy current technique can also be applied to other metallic construction materials (e.g. stainless steels) if required by the design specification. The techniques can be applied to coated and uncoated objects during fabrication and in service, onshore and offshore. The examination can be carried out on all accessible surfaces and on welds of almost any configuration. Usually, it can be applied in the as-welded condition. However, a very rough surface can prevent an efficient examination.
