ISO 17643:2015定义了涡流检测技术，主要用于检测铁素体材料（焊接材料、热影响区、基材）中的表面断裂和近表面平面不连续性。 涡流检测也可以指定用于非铁素体材料，例如在应用标准中。 该技术可应用于陆上和海上制造和使用期间的涂层和未涂层物体。 涡流检测可在所有可接近表面和几乎任何结构的焊缝上进行。 除非本国际标准中的特定条款另有规定，否则ISO 15549的一般原则适用。 注:涡流检测通常在焊接状态下进行。然而，非常粗糙的表面光洁度可能会影响结果的准确性。

ISO 17643:2015 defines eddy current testing techniques for detection of surface breaking and near surface planar discontinuities, mainly in ferritic materials (weld material, heat-affected zones, base material). Eddy current testing can also be specified for use with non-ferritic materials, for example in an application standard. The techniques can be applied to coated and uncoated objects during fabrication and in service, both onshore and offshore. Eddy current testing can be carried out on all accessible surfaces and on welds of almost any configuration. Unless otherwise specified at specific items in this International Standard, the general principles of ISO 15549 apply. NOTE Eddy current testing is usually performed in the as-welded condition. However, the accuracy of the results can be affected by very rough surface finishes.
