scope:

This section defines eddy current testing techniques (ET) for detection of surface breaking and near surface planar defects in:

- welds

- heat affected zone

- parent material.

ET can be applied on coated and uncoated objects and the testing can be carried out on all accessible surfaces on welds of almost any configuration.

For other applications than weld testing, it is recommended that eddy current testing is done according to EN ISO 15549.

Usually, it can be applied in the as-welded condition. However, a very rough surface may prevent an efficient testing.

The eddy current testing method includes also alternating current field measurement (ACFM). If this method is applied, written procedures shall be established according to recognised standards and are subjected for approval by the Society before the testing starts.
