BS EN ISO 15548-1:2008 Non-destructive testing. Equipment for eddy current examination. Instrument characteristics and verification
BS EN ISO 15548-1 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 BS EN ISO 15548-1.
BS EN ISO 15548-1 gives neither the extent of verification nor acceptance criteria for the characteristics. They are given in the application documents.
