ISO 15549 defines the general principles to be applied to non-destructive eddy current examination of products and materials in order to ensure defined and repeatable performance.
ISO 15549 includes guidelines for the preparation of application documents that describe the specific requirements for the application of the eddy current method to a particular type of product.
ISO 15549 on non-destructive testing is useful for:
The eddy current examination is based upon the induction of an alternating electric current in a conducting material. The quantity measured and analysed is related to the distribution of the induced currents and it is represented by a vector in the complex plane. The examination specified in ISO 15549 employs an eddy current instrument, one or more probes, and interconnecting cabling.
This combination, together with any mechanical equipment and peripheral units for data storage, etc., forms the examination system. The performance of the examination system shall be verified at specified intervals both on-site and in the laboratory. The verification shall be in accordance with ISO 15549.
