ISO 15548-2:2008确定了探头及其互连元件的功能特性，并提供了测量和验证方法。 对这些特性的评估允许对涡流设备进行明确的描述和可比性。 通过仔细选择特性，可以为特定应用设计一致且有效的涡流检测系统。 如果使用附件，应使用ISO 15548-2:2008的原则对其进行描述。 ISO 15548-2:2008未给出特性的验证范围或验收标准。 这些都在申请文件中给出。

ISO 15548-2:2008 identifies the functional characteristics of a probe and its interconnecting elements 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 should be characterised using the principles of ISO 15548-2:2008. ISO 15548-2:2008 does not give the extent of verification nor acceptance criteria for the characteristics. These are given in the application documents.
