Describes the functional characteristics of a general-purpose eddy current instrument and provides methods for their measurement and verification.

This part of ISO15548 identifies the functional characteristics of a general-purpose eddy current instrument and provides methods for their measurement and verification.

The evaluation of these characteristics permits a well-defined description and comparability of 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 this part of ISO15548.

This part of ISO15548 gives neither the extent of verification nor acceptance criteria for the characteristics. They are given in the application documents.
