Le présent document définit des techniques de contrôle par courants de Foucault utilisées pour la détection de défauts débouchants et de défauts plans sous-jacents.
<p>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).</p> <p>Eddy current testing can also be specified for use with non-ferritic materials, for example in an application standard.</p> <p>The techniques can be applied to coated and uncoated objects during fabrication and in service, both onshore and offshore.</p> <p>Eddy current testing can be carried out on all accessible surfaces and on welds of almost any configuration.</p> <p>Unless otherwise specified at specific items in this International Standard, the general principles of ISO 15549 apply.</p> <p>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.</p>
