TS EN ISO 12718

TS EN ISO 12718 is a vocabulary standard for the terms used in eddy current testing. Standards of this type help keep technical communication consistent across laboratories, production environments, inspection reports, and training material. Because eddy current testing relies on electromagnetic interaction in conductive materials, precise terminology is especially important for correct interpretation and repeatable discussion of results.

Why terminology matters in eddy current testing

Eddy current testing uses a technical language built around concepts such as probes, coils, frequency, phase, impedance, and signal interpretation. A vocabulary standard defines these terms so that operators, inspection engineers, quality personnel, and equipment manufacturers use the same language for the same concept. That improves consistency in procedures, documentation, and reporting. The scope of this standard is the definition of terms; it does not, from the supplied scope, establish a particular inspection setup, test parameter, or acceptance criterion.

Its place within non-destructive testing

Eddy current testing is a widely used non-destructive testing method for assessing near-surface discontinuities, material variations, and some geometry-related effects in conductive materials. Standardized terminology supports training and technical documentation by giving the method a common conceptual framework. In that sense, TS EN ISO 12718 supports understanding and communication of the method rather than prescribing how the inspection itself must be performed.
