ISO 15548-3:2008 identifies the functional characteristics of a general-purpose eddy current system and provides methods for their measurement and verification.

The evaluation of these characteristics permits a well-defined description and comparability of an eddy current equipment.

By careful choice of the characteristics, a consistent and effective eddy current examination system can be designed for a specific application.

Where accessories are used, these are characterised using the principles of ISO 15548-3:2008.

ISO 15548-3:2008 does not give the extent of verification nor acceptance criteria for the characteristics. These are given in the application documents.
