TS 11085 EN 1330-5

TS 11085 EN 1330-5 is a terminology standard for nondestructive testing that defines the terms used in eddy current testing. Its purpose is to establish a common technical language for the method, so that inspection personnel, reports, and related documentation refer to the same concepts in a consistent way.

Why terminology matters in eddy current testing

Eddy current testing is based on electromagnetic induction in electrically conductive materials. An alternating magnetic field from a probe or coil induces circulating currents in the test piece, and those currents are affected by surface-breaking discontinuities, geometry changes, electrical conductivity, and magnetic permeability. Because the same physical phenomenon can be described through signal behavior, probe arrangements, reference conditions, or indication interpretation, a terminology standard is valuable for keeping those ideas precise and aligned.

What this part covers

• It defines the terms used in eddy current testing.
• It belongs to the broader nondestructive testing terminology series and supports a shared vocabulary across related documents.
• It is focused on definitions rather than on test procedures, acceptance limits, or numerical performance requirements.

For practical use, this kind of vocabulary standard helps manufacturers, inspectors, trainers, and specification writers use key words in the same way across different contexts. Distinctions such as indication versus flaw, calibration versus verification, and probe behavior versus material response are central to clear communication in eddy current practice. This record also represents a withdrawn TSE edition; while it is based on EN 1330-5:1998, the listing itself identifies the subject area and document type rather than a standalone test method.
